Flooding is one of the causes of environmental damage worldwide. Several things that can affect flooding in urban areas, Palembang experiences periodic flooding problems, especially every rainy season. The data in this article consists of primary data obtained from location surveys in retention ponds, including: documentation, topography, depth of retention ponds and secondary data from related agencies, including: location maps, climatology, regional topography. Palembang City has varying levels of flood vulnerability: high (Jakabaring, Kertapati, Plaju, and Seberang Ulu), medium (Ilir Barat and Sukarame), and low (Alang-Alang Lebar). Lowland areas with poor drainage systems require more attention. Retention ponds play an important role in managing rainwater runoff, such as the Jakabaring Sports Hall (200,000 m²), Ogan Permai Indah (22,217 m²), and Brimob Demang Lebar Daun (30,000 m²). The city's topography, which is mostly flat and low, especially around the Musi River, further increases the risk of flooding.

The impact of beaver ponds on tree stand in a river valley The number of beavers in Poland rapidly increases which may result in conflicts between man and beavers. Despite the fact that beaver ponds play important role in increasing of biodiversity, water retention and soil moisture, they may also cause the die out of tree stands in river valleys and lead consequently to disappearance of typical riparian forest communities. Field studies demonstrated that long term flooding inhibited tree growth. Many trees died after 2 years of flooding. Long flooding caused the death of 80% of trees.

Full textAbstract:
Mediterranean temporary ponds on Doñana’s aeolian sands form an extensive system of small dynamic water bodies, dependent on precipitation and groundwater, of considerable importance for biodiversity conservation. Different areas of the aeolian sands have received different levels of environmental protection since 1969, and this has influenced the degree of conservation and the flooding dynamic of these temporary surface waters. We use the Landsat series of satellite images from 1985 to 2014 to study the temporal dynamic of small temporary water bodies on the aeolian sands in relation to the protection level and to distance to water abstraction pressures from agriculture and residential areas. The results show that even with small and ephemeral water bodies optical remote sensing time-series are an effective way to study their flooding temporal dynamics. The protected areas of the aeolian sands hold a better preserved system of temporary ponds, with a flooding dynamic that fluctuates with precipitation. The unprotected area shows an increase in mean hydroperiod duration, and surface flooded, and a decline in hydroperiod variability. This seems to be due to the creation of irrigation ponds and the artificialization of the flooding regime of the natural temporary ponds, that either receive excess irrigation water or dry-up due to the lowering of the groundwater table level. Although a decline in hydroperiod duration of temporary ponds is seen as negative to the system, an increase in hydroperiod of surface waters due to artificialization, or a decline in variability cannot be considered as positive compensatory effects.

Full textAbstract:
AbstractThe amphibian community of the Biological Reserve of Doñana (SW Spain) is composed of 10 species, their period of larval occurrence commonly taking place from autumn to early summer, although it may vary from year to year in relation to the flooding conditions of ponds. A segregation is observed according to temporal use of temporary ponds by larvae of different species. Pelobates cultripes and Discoglossus galganoi tadpoles occur in ponds during their whole persistence, from flooding to drying up. Hyla meridionalis, Triturus marmoratus and Triturus boscai larvae commonly exploit a shorter temporal range, appearing about two months later until early summer. Bufo bufo, Bufo calamita and normally also Rana perezi have the shortest larval periods, of about two months. Rana perezi is also characterized by its delay in temporal use of the ponds in comparison with the other species. The flexibility of the larval period season is considered an adaptation to the unpredictability of temporary ponds. Thus, under certain climatic conditions, the two first groups of species may occur in the same temporal range.

Full textAbstract:
A study was conducted to determine fish yields from flood depended ponds in Rufiji floodplain, Tanzania. Eight ponds were constructed during dry season in two sites besides two floodplain lakes, Ruwe and Uba. These ponds were self-stocked with different fish species from the lakes. More than eight species were trapped and<em>Oreochromis urolepis, Labeo congoro and Clarias</em> species were considered as good candidates for aquaculture. Other small fish species were harvested immediately after flood recession and the three key species were cultured for the maximum of seven months. However, other species in small quantities were remained in the ponds for the whole period of experiment. Water quality parameters were monitored throughout the study period. The relationships between water quality variables and flooding events were determined using canonical correspondence analysis (CCA). Other parameters included in the relationships were fish density, manure and number of species trapped and cultured. Dissolved oxygen and pH decreased with time in both sites. Fish yields were influenced by some water quality, flooding episode and other management variables. Chlorophyll-<em>a</em> was the only environmental variable that showed a significant correlation with fish yield (P< 0.01). Fish density and number of species trapped showed a significant effect on the fish yield (P<0.05). Re-connectivity between ponds and lakes was strongly positively correlated with yield. It can be concluded that some water quality variables, flooding and management parameters were responsible for the observed yield.

Full textAbstract:
This study used a multiscale analysis of relationships among the bitterling and mussel communities, lentic habitat structures with conditions and flooding frequency, and channel characteristics for application in ecological sediment management. From the Kizu River in Japan, 120 lentic habitats were sampled in 2007 and 2010. The floodplain vertical shape index (FVSI), which indicates the degree of convexity or concavity of the vertical shape of a floodplain, was used as channel characteristics using historical cross-section profiles obtained from 1960 to 2012. For examining the relationships between bitterlings/mussels and each habitat condition or structure, abundance values of bitterlings and mussels were transformed into habitat suitability index (HSI). Furthermore, the relationships between the number of habitat structures and FVSI were analyzed. The results indicated that bitterlings and mussels are more abundant in terrace ponds than in active ponds, especially so in terrace ponds located in the lower area of bars with a flooding frequency of 8–16 days/year (bitterlings), those located in the lower area of bars with a flooding frequency of 8 days/year, and those located in the upper area of bars with a flooding frequency of 16–22 days/year (mussels). These ponds tended to have less than 1 cm mud depth that was negatively related to abundance of mussels. These suitable habitat types tended to be located in channels with a floodplain vertical shape index between −0.35 and 0.05. We established countermeasures to prevent channel types with floodplain vertical shape index exceeding 0.05 instead of restoring the previous channel conditions.

Full textAbstract:
Increasingly severe flooding disasters have caused heavy casualties and property losses worldwide. Traditional Chinese villages that rarely experienced flooding disasters in the past have begun to frequently suffer from floods due to unreasonable reconstruction activities such as ground hardening and pond filling caused by urbanization. However, previous studies on hydrological changes and flood disasters caused by reconstruction activities in rural areas are scarce, especially lacking in quantitative analysis and research. In this study, the Storm Water Management Model (SWMM) is used to construct two hydrological models before and after the reconstruction of Hezhai Village, a traditional Chinese village. By simulating and comparing the changes in hydrological indicators of the two models, this study quantitatively analyzes how reconstruction activities caused changes in surface runoff and flooding disasters in Hezhai Village. The results show that the increase in the impervious ratio in the village has obvious effects on the total runoff, peak runoff, and runoff coefficient. And the reconstruction of ponds and canals has a notable impact on flooding. This study further delves into the logic of flooding at ponds and ordinary nodes and analyzes the specific reasons for flooding in Hezhai Village. Based on this, the paper provides recommendations for the optimization of the reconstruction of Hezhai Village.

The purpose of the study is to identify various climatic change risks encountered by fish farmers while doing freshwater aquaculture in the unmanaged ponds of district kaushambi Uttar Pradesh. The various climate change risks which were faced by rural farmers of Kaushambi are water quality, flooding of ponds, less rain, heavy mortality of fishes, planktonic collapse, long dry spells, disease outbreak, destruction of embankments etc. The study also includes the measures to encounter these risks. To maintain the quality of water the farmers have used lime, manure, alum, KMnO4, salt and exchange of water. To control the flooding of ponds the farmers raises embankments by bamboo fencing with net. They have filled their ponds with pumps from canals / rivers and tube well water to face the problem of less rain and long dry spells. To avoid the heavy mortality of the fishes they have used early harvest, liming, shading and water movement by beating of water for oxygenation. To overcome with the planktonic collapse the farmers have used cow dung, gobar gas slurry, use of khari, choker in the water and exchange of 50 percent water. To control the disease outbreak the farmers have adopted lime, KMnO4, medicines, neem leaves, banana stem etc.

Full textAbstract:
In order to reduce the flooding risk in urban and peri-urban river catchments, retention ponds or wet detention ponds are often used. However, there has been little work that uses distributed hydrological modeling to consider their optimum location and design in order to reduce the flood risk in a river catchment. This work considers two existing and two potential ponds in the 22.8 km2 Braid Burn catchment, Edinburgh, Scotland. Using the Shetran physically based distributed hydrological model, the effect of these ponds on the river discharges for eight measured rainfall events and two design rainfall events is considered. The results show the larger Blackford pond is best at reducing the peak discharge at the catchment outlet. The other three ponds are designed to be almost the same. The potential pond in the upper part of the catchment reduces the peak discharge at the outlet; the pond in the middle at Oxgangs makes little difference to the peak discharge, while the potential pond in the lower part of the catchment increases the peak discharge at the outlet. These results show that when considering flood risk, the location of a retention pond within a river catchment is important, and it can make the flooding worse at the outlet if it is located in the wrong location. This work suggests the pond should be located in the upper part of the catchment, although the ideal location will depend on the catchment’s shape and lag time.

Full textAbstract:
The abundance of polyphenolic compounds in four temporary ponds in Donana National Park (south-western Spain) was examined during three years of varying hydrology (1989-92). During flooding in 1989-90, the ponds received large amounts of allochthonous organic matter, as indicated by the relative increases in dissolved organic carbon (70-120 mg C L-1), dissolved polyphenolic compounds (7.6-12.2 mg L-1) and water colour (17-33 m-1, A440). As the ponds dried out, the concentration of dissolved polyphenols decreased rapidly in ponds with abundant submerged macrophytes, whereas the concentrations increased in unvegetated ponds. Very low concentrations of dissolved polyphenols (1.0-2.8 mg L-1) were measured in all ponds when they refilled again after drought in October 1991. A large percentage of the initial amount of polyphenols (80%) and of soil organic matter (71%) disappeared from surface sediments after four months of drought. The temporary nature of these ponds enhanced the disappearance of allochthonous organic matter. It is suggested that sunlight and aerobic conditions promote the decrease of organic matter in pond sediments during drought.

Full textAbstract:
The coastal areas of Florida, United States, are exposed to increasing risk of flooding due to sea level rise as well as severe hurricanes. Florida regulations suggest constructing stormwater retention ponds as an option to retain excess runoff generated by the increased impervious area and to protect the environment by reducing pollutants from new developments. Groundwater level rise can significantly lower the soil storage capacity and infiltration at retention ponds, in turn, reducing the pond’s capacity to capture consecutive storms due to longer pond volume recovery time. Partial groundwater inundation can affect retention ponds’ ability to decrease peak flow rates and keep the post-development outflow lower than or equal to pre-development conditions. In this paper, the reliability and performance of a retention pond near Tampa Bay, Florida, was evaluated under sea level rise conditions. An integrated surface water and groundwater model was developed, and the groundwater table was projected for future conditions as a function of sea level rise. The results showed that sea level rise could increase the seasonal high water elevation of the retention pond up to 40 cm by mid-21st century. This increase lowered the reliability of the retention pond by about 45%. The pond failed to recover the designed treatment volume within required 72 h because of the high groundwater table, increasing the risk of pollutant discharge. Furthermore, the peak flow and volume of runoff significantly increased under sea level rise and associated groundwater table rise conditions. The study results suggest that it is imperative to consider future sea level rise conditions in stormwater design in low-lying coastal areas of Florida and around the world to prevent poor pond performance and increased risk of flooding in the future.

Rain is water vapor that is condensed and falls from the atmosphere to the earth in all its forms in the hydrological cycle. Rainwater must be managed properly, if it is not managed it will cause various problems, such as flooding, soil erosion, and water pollution as well as negative impacts on people's health and welfare. Along with the influx of development investors into the city of Samarinda, the city's development continues to increase and makes this city continue to grow. However, during this growth and development, Samarinda City cannot be separated from the problem of flooding. Floods not only submerge housing and settlements, they can also damage community socio-economic service facilities and public infrastructure and can even claim lives, losses will be greater if economic and government activities are disrupted or even stopped. This research aims to analyze the management of rainwater in buildings and plots to reduce flooding in the city of Samarinda using the 95th percentile method by the mandate of Government Regulation Number 16 of 2021 Article 38 which states that every building, by its function and classification, must be equipped with a management system. Rainwater. The research was conducted in Samarinda using analysis and calculation methods. The research stages are divided into 3 stages, namely literature study, data collection, and data processing stage. The research results show that (1) by managing rainwater in buildings and plots through rainwater utilization and soil infiltration, rainwater runoff will be reduced; and (2)from the rainwater management calculation process using the 95th percentile method, the City of Samarinda is required to manage 21,185,343.9 m³ of rainwater. Rainwater management carried out by the Samarinda City Government can take the form of creating retention ponds (folders) in several areas, especially those where inundation or flooding frequently occurs, and in each building or area according to its function and classification, a retention or ground pond is provided.

Full textAbstract:
This study focuses on assessing the density of mangrove forests on the north coast of Demak Regency as an independent mitigation effort against tidal flooding. The impact of tidal flooding can be observed directly, such as damaged ponds and agricultural land, inundated road infrastructure, submerged houses, and disruption of livelihoods. This study is crucial because it provides data and spatial analysis to understand the current level of mangrove density, identify vulnerable areas and inform appropriate mitigation actions before the impact of tidal flooding. The study's novelty is that it focuses on specific density and vulnerability levels and uses significant short-term cover change analysis. Using spatial analysis methods through Geographic Information Systems (GIS) and satellite imagery from 2018-2023, several areas along the coast have mangrove densities varying from 1200-3400 trees per hectare. There was a 27.3% reduction in mangrove cover mainly due to changes in land use to ponds. Overlay analysis combining mangrove density with flood hazard maps and geographic information also maps how different mangrove areas are strongly related to tidal flooding. Areas with mangrove density <2000 trees per hectare are much more vulnerable to tidal flooding, which is worse at lower and better at higher ranges. The findings suggest that coastal engineering using soft hybrids, which integrate breakwater structures and mangrove rehabilitation, will be more effective in achieving long-term coastal resilience than using hard engineering techniques alone, support the integration of mangrove density thresholds into coastal infrastructure planning to enhance resilience against tidal flooding. As an effective policy for coastal management, a minimum standard of 3,000 mangrove trees per hectare is needed, and Demak Spatial Planning is needed to focus more on mangrove conservation within the Demak policy framework.

This research aims to investigate two main aspects in Padang Gelugur Subdistrict, Pasaman Regency: first, the change in paddy field area into fish ponds from 2017 to 2022; second, to analyze the factors influencing this land conversion. The research method used is a mixed methods approach, which integrates quantitative and qualitative data to answer research questions related to behavior, social, and health aspects. The research results indicate that during the period from 2017 to 2022, approximately 144 hectares of paddy fields were converted into fish ponds. The main factors driving the community to undertake this land conversion include the significant income difference between paddy harvests and fish ponds, with income from fish ponds tending to be higher. Additionally, educational factors and weather conditions also play a significant role, particularly as Padang Gelugur Subdistrict frequently experiences high rainfall intensity, which can lead to flooding and crop failure.

Full textAbstract:
Tidal estuaries constrained by embankments in the Sundarbans have failed to respond to a &gt;1 m sea level rise over the past 100 years since their construction. This paper shows that this has led to a disequilibrium morphology leading to channel erosion that has undermined embankments, causing mass failure, breaching and subsequent flooding during surge events. Predicted future sea level rise will exacerbate this trend and managed realignment of embankments will be needed to accommodate it. Management practices have, however, modified this underlying process of erosion. The increasing practice of severing tributary channels from the main channel using flap sluices to create freshwater storage ponds has, in many cases, reduced tidal flow in the main channels so that they are not only accreting rather than eroding, but capable of accommodating future sea level rise without erosion. In contrast, the rapid spread of salt water aquaculture in the Sundarbans, flooding previous paddy land, has led to an increase in tidal discharge and accelerated erosion of the embankments in estuary channels conveying water to the ponds. This paper concludes that existing management practices may have a more significant impact on flooding in the Sundarban than the predicted sea level rise due to global warming.

Annual flooding during the rainy season at the Bogor City Regional General Hospital since 2016 has created a significant issue, potentially triggering a domino effect impacting the hospital, its visitors, staff, and patients. This study aims to design a rainwater management system to mitigate excessive rainwater puddles, which causes flooding, using the Zero Runoff System (ZROS) concept. The ZROS concept focuses on establishing an eco-drainage system for this government-owned hospital to address the issue of inundation effectively. This study employs rainfall-runoff modeling with statistical methods such as Distribution Testing and Chi-Square Analysis to determine data fit. Hydrological analysis is conducted to calculate design discharge and runoff volumes that can be discharged to detention ponds. The results show that the required storage volume is 72.35 m³, leading to the recommendation of constructing a detention pond system. The proposed detention system consists of two ponds, each measuring 5 m x 3 m with a depth of 2.5 m, providing a total storage capacity of 75 m³ to meet the required runoff control needs. The implementation of this system is expected to provide an integrated solution related to the flood issue at the Bogor City Hospital, considering that the hospital is a public facility that is prone to piles of garbage, for example, a control tub is made before water enters the Detention Pond. The chamber includes a trash screen with a closable outlet to facilitate maintenance and ensure the detention ponds remain effective.

Full textAbstract:
Climatic scenarios for the Mediterranean predict an increase in drought and erratic precipitation, which may affect waterbirds breeding in freshwater habitats. Artificial wetlands may provide an alternative for these species when conditions in natural habitats deteriorate. We studied Little Ringed Plovers Charadrius dubius nesting in natural streams and agricultural ponds in southern Portugal. Based on 24 nests and 31 colour-ringed adults, we describe nest-site characteristics, breeding parameters and site fidelity. In streams, nests (n = 17) were in sites with more abundant and coarser gravel, while in ponds there was more vegetation around the nest (n = 7). In both habitats, nests were close and at similar distances to water, but this was unrelated to nest outcome (success of 30.8% across habitats). Nest failure in natural streams was mostly attributable to flooding after heavy rains, while in agricultural ponds cattle trampling was the main cause of failure. Based on their renesting capacity and relatively high breeding site fidelity (25%–36% return rate to same area), we suggest that Little Ringed Plovers may trade-off the overall better conditions of natural streams (i.e. higher availability of nesting substrate, food resources and lower disturbance from cattle) against the stochastic risk of floods. Nevertheless, under current predictions of climate change, agricultural ponds can provide more stable and reliable nesting conditions for this and other species, as unpredictable changes in Mediterranean streams’ flooding regimen may become more frequent. Despite the limitations of our dataset, we provide novel information on the breeding biology of this understudied species and highlight its potential for future research.

The Lampoko watershed is the biggest watershed in South Sulawesi's Barru Regency. Flooding is a common occurrence in this area, particularly tidal flooding. To get around this, this research uses a geographic information system to estimate land cover and reveal how an organization will grow in the future. This forecast is meant to help plan preventive measures in organizational regions where flooding is anticipated. The CA-Markov model was used to analyze satellite imagery data (Landsat 8 OLI TIRS Year 2015-2021). The findings revealed an increasing pattern of land cover change in several land cover classes that were hubs of communal activity including villages, fisheries (ponds) and agricultural (rice fields). Balusu, Lampoko and Ajakkang are areas that need to be prepared for since they are part of regions with a high likelihood of flooding in the future.

Full textAbstract:
Floods are the dominant color of the interaction of human activities and natural mechanisms that occur every year in the city of Jakarta. Various efforts have been made to reduce flooding in Jakarta, but flooding is still the dominant color, especially on the banks of the Ciliwung River. On the banks of the Ciliwung River, Tebet, Matraman and Jatinegara sub-districts are the three areas that experienced the most severe overflows of the Ciliwung River. Flood mitigation efforts in these three areas have been carried out in the form of increasing the drainage capacity of the Manggarai Gate and normalizing the river in the form of dredging and construction of embankments. However, this effort is not optimal because the implementation of normalization is hampered by social conflicts. This paper discusses mitigation efforts in the form of normalization and combination with retention ponds which are carried out by simulating flooded areas. Completion of the normalization of the Ciliwung River is not the best solution to deal with flooding in Jakarta. The flood volume which usually occupies the flood area flows quickly due to changes in the geometry of the river and causes changes in the hydrograph peak and causes flooding in the downstream part of the study area causing an increase in inundation area in Manggarai up to 200%. On the other hand, the use of retention/storage ponds on limited land has been able to reduce flood inundation by 10%. Therefore, staging in the planning and construction of flood mitigation infrastructure needs to be considered and planned thoroughly.

Full textAbstract:
Riverside pit-ponds are one of the hidden dangers of flood control project safety. At present, the safety evaluation of riverside pit-ponds is limited to the seepage and stable safety review of the dam, and the impact of the pit on the river flow is not considered. In this paper, a two-dimensional mathematical model of flow is established. Pressure correction method is used to solve the pressure-velocity coupling. Topographic cutting method is used to deal with the dynamic boundary problem. The model grid of the pit-ponds area is encrypted. The accuracy of the model in the analysis of river hydrodynamics is verified by an example. The model is applied to the evaluation of the impact of the pit-ponds on river flooding. Taking some riverside pit-ponds of the Yellow River as an example, the river water level, velocity, and flow in the present condition and the backfill condition are simulated by the model. The results show that the existence of these riverside pit-ponds only affects the hydrological features of regions around the pit-ponds, and the impact is too insignificant to threaten the hydrological safety. Through the hydrological safety assessment of the project, it is shown that the combination of the two-dimensional flow mathematical model with seepage, anti-sliding, and seismic safety review can comprehensively assess the hydrological safety of dike engineering.

Full textAbstract:
This paper presents the developments towards the next generation of overland flow modelling of urban pluvial flooding. Using a detailed analysis of the Digital Elevation Model (DEM) the developed GIS tools can automatically generate surface drainage networks which consist of temporary ponds (floodable areas) and flow paths and link them with the underground network through inlets. For different commercially-available Rainfall–Runoff simulation models, the tool will generate the overland flow network needed to model the surface runoff and pluvial flooding accurately. In this paper the emphasis is placed on a sensitivity analysis of ponds and preferential overland flow paths creation. Different DEMs for three areas were considered in order to compare the results obtained. The DEMs considered were generated using different acquisition techniques and hence represent terrain with varying levels of resolution and accuracy. The results show that DEMs can be used to generate surface flow networks reliably. As expected, the quality of the surface network generated is highly dependent on the quality and resolution of the DEMs and successful representation of buildings and streets.

Abstract Zooplankton community assembly after flooding in temporary ponds depends mostly on abundance and diversity of the dormant propagule bank. However, our understanding of the hatching patterns of zooplankton is imperfect. We performed an ex situ experiment to study the species composition and temporal sequence of zooplankton emergence from sediments in three ponds that were restored at different times: 1998, 2003 and 2007. The patterns of species hatching observed in our microcosms were compared with the emergent zooplankton community of their equivalent, synchronically inundated ponds. An escalation in species richness and a delay in hatching time were detected with increasing restoration age. In addition, some discrepancies between the egg bank and active populations were observed, especially in the oldest pond. This study illustrates the use of hatching experiments in comparing ponds with different characteristics. Nevertheless, egg bank hatching and water column sampling should complement each other in order to afford a full reflection of past diversity and contribute to a better understanding of the efficiency of restoration practices.

Abstract During the last 15 years, many stormwater ponds were built in Canada. These ponds were designed to control runoff flows by peak shaving and thereby prevent flooding resulting from urbanization, but they are ineffective in protection of water quality in the receiving waters. Thus, one of the emerging challenges in urban water management is the retrofitting of existing stormwater ponds to meet the current environmental concerns. The retrofitting measures proposed include changes in flow regimes, storage pool volumes and flow velocities, achievable by structural changes in inlet, storage and outlet structures; treatment of runoff by sedimentation or filtration; enhancement of biological processes contributing to pollutant removal through longer detentions and introduction of aquatic plants; and, improvement of aquatic life habitat. A case is made for an ecosystem approach where the pond is one element in the urban stormwater treatment train which controls catchment, pond and receiving waters.

In flood-driven environments the life cycles of organisms are regulated in function of the water regime. The objective of this work is to analyse the phenophases of flowering and fructification of two species of amphibious aquatic macrophytes, Polygonum hispidum Kunth and P. punctatum Elliott, with regard to the flooding cycle of the Brazilian Pantanal. We collected monthly data in 26 plots of 20 ponds during two years. The flooding phases were classified as drought, rising, flood, and receding. The periods with an abundance of water (rising, flooding, and receding) were the most important for reproduction. Both species bear fruits at flood, when the water is deepest and remains until receding, and most seeds are dispersed. The synchrony between reproductive cycles and these flood phases suggests the importance of seasonality in the reproductive patterns of these species.

Full textAbstract:
AbstractBeavers (Castor spp.) are ecosystem engineers that induce local disturbance and ecological succession, which turns terrestrial into aquatic ecosystems and creates habitat heterogeneity in a landscape. Beavers have been proposed as a tool for biodiversity conservation and ecosystem restoration. So far, most research has compared biodiversity in beaver wetlands and non-beaver wetlands, but few studies have explored how beaver-created succession affects specific taxa. In this study, we investigated how water beetles responded to different successional stages of wetlands in a beaver-disturbed landscape at Evo in southern Finland. We sampled water beetles with 1-L activity traps in 20 ponds, including: 5 new beaver ponds, 5 old beaver ponds, 5 former beaver ponds, and 5 never engineered ponds. We found that beaver wetlands had higher species richness and abundance than non-beaver wetlands, and that new beaver wetlands could support higher species richness (321%) and abundance (671%) of water beetles compared to old beaver wetlands. We think that higher water beetle diversity in new beaver ponds has resulted from habitat amelioration (available lentic water, shallow shores, aquatic vegetation, and low fish abundance) and food source enhancement (an increase of both dead and live prey) created by beaver dams and floods. We conclude that using beavers as a tool, or imitating their way of flooding, can be beneficial in wetland restoration if beaver population densities are monitored to ensure the availability of newly colonizable sites.

Zooplankton assemblages in neighboring ponds can show important spatial and temporal heterogeneity. Disentangling the influence of regional versus local factors, and of deterministic versus stochastic processes has been recently highlighted in the context of the metacommunity theory. In this study, we determined patterns of temporal and spatial variation in zooplankton diversity along one hydrological year in restored ponds of different hydroperiod and age. The following hypotheses regarding the assembling of species over time were tested: i) dispersal is not limited in our study system due to its small area and high exposure to dispersal vectors; ii) community dissimilarity among ponds increases with restoration age due to an increase in environmental heterogeneity and stronger niche-based assemblages; and iii) similarity increases with decreasing hydroperiod because hydroperiod is a strong selective force filtering out organisms with long life cycles. Our results confirmed dispersal as a homogenizing force and local factors as gaining importance with time of restoration. However, short hydroperiod ponds were highly dissimilar, maybe due to the environmental differences among these ponds, or to high stochasticity followed by priority effects under a weak selection pressure. By adding a temporal dimension to the study of zooplankton structuring, we could identify the first months after flooding as being crucial for species richness, especially in short hydroperiod ponds; and we detected differences in seasonal species richness related to hydroperiod and pond age.

Full textAbstract:
Advancements in smart sensing and control technologies enable urban drainage engineers to retrofit stormwater storage facilities with real-time control devices for mitigating stormwater in-site overflow, downstream flooding, and overloaded total suspended solids (TSS) in drainage pipes. While the smart technology can improve the performance of the static drainage systems, coordinatively controlling multiple valve and gate operations poses a significant challenge, especially at a large-scale watershed. Using a benchmark stormwater model located at Ann Arbor, Michigan, USA, we assessed the impact of different real-time control strategies (local individual downstream control and system-level multiple control) on balancing flooding mitigation at downstream outlets and TSS reduction at upstream storage units, such as detention ponds. We examined changes in peak water depth, outflow, and TSS as indicators to assess changes in water quantity and quality. The results indicate that system-level control can reduce peak water depth by up to 7.3%, reduce flood duration by up to 34%, and remove up to 67% of total suspended solids compared with a baseline uncontrolled system, with the outflow from upstream detention ponds being the most important hydraulic indicator for control strategy rule set-up. We find that system-level control does not always outperform the individual downstream controls, particularly in alleviating flooding duration at some downstream outlets. With urban growth and a changing climate, this research provides a foundation for quantifying the benefits of real-time control methods as an adaptive stormwater management solution that addresses both water quantity and quality challenges.

Many regions in Europe face increasing issues with flooding and droughts due to changing rainfall patterns caused by climate change. For example, higher rainfall intensities increase urban flooding. Nature-based solutions (NbS) are suggested as a key mitigation strategy for floods. This study aims to address and mitigate the challenges faced in Tivoli natural park in Ljubljana regarding high peak discharges and low-flow issues in the creek entering the sewer system. The study involves setting up, calibrating and validating a Hydrologic Engineering Centre–Hydrologic Modelling System (HEC-HMS) model using available data. This study analyses NbS, such as small ponds, green roofs and permeable paving, to reduce peak discharge. Runoff was reduced by an average of 32.4% with all NbS implemented and peak discharge by 20 L/s. Permeable parking performed best, with an average runoff reduction of 6.4%, compared to 4.8% for permeable streets and 5.9% for green roofs. The ponds reduced peak discharge, although their effectiveness varied between rainfall events. Rainfall events with higher volumes and durations tended to overwhelm the proposed solutions, reducing their effectiveness. The ability of HEC-HMS to model NbS is also discussed. The curve number (CN) parameter and impervious % alterations to simulate NbS provided quantitative data on changes in runoff and discharge.

Expansion of industrial areas, aquaculture, settlements, and limited knowledge of the community about the function of mangroves allegedly led to the conversion of mangrove functions in the early 1990s. This study aimed to map the condition of mangroves from 1988, 1990, 1995, 2008, to 2021 and their effect on the widespread of tidal flooding in three villages (Mangkang Kulon, Mangunharjo, Mangkang Wetan) in Tugu subdistrict, Semarang City. The research method was carried out by using spatiotemporal analysis of Landsat 5 and Landsat 8 imagery through the supervised approach (Maximum Likelihood algorithm). In order to map the correlation of mangrove damage with the widespread impact of tidal flooding, an overlay analysis of land use maps was carried out in 1988, 1990, 1995, 2008 and 2021. The results of the study showed that mangrove damage is correlated with the widespread of tidal flooding that drowns settlements, ponds, and agricultural land. Data analysis showed that the mangrove area in three villages has decreased from 1988 to 2021, covering an area of 242.66 ha. This condition is one of the triggers for the increase in tidal flooding area from 1988 to 2021, covering an area of 253.135 ha. As a natural barrier to prevent abrasion and tidal flooding, mangrove conservation is very necessary, considering the impact of tidal flooding on the coast of Semarang City is increasingly widespread.

Flooding is a globally common problem in metropolitan areas including Jakarta, Indonesia. The increased intensity and frequency of rainfall caused by climate change and rapid urbanization have raised the risk of flooding in urban areas. One solution is to implement polders to mitigate flooding in coastal metropolitan areas. Regrettably, the current polder system is inadequate for managing flooding due to rapid land-use changes and regional expansion. This study analyzes flood control in the Jakarta region using the East Sunter Polder System, which experienced flooding in both 1990 and 2020 despite the implementation of the polder system. The polder system, consisting of four catchment areas—Petukangan, KBN 1/Sukapura, KBN 2, and Kebantenan—faces drainage challenges exacerbated by rainfall. To mitigate flood risks, Nature-Based Solutions (NBSs) have been implemented, including retention ponds and long storage systems. Hydrological and hydraulic analyses were conducted using HEC-HMS and HEC-RAS, and ArcGIS was employed for floodplain integration. This study underscores the significance of incorporating NBSs in urban flood management, demonstrating how they enhance resilience and mitigate flood risks. By integrating NBSs into the urban planning framework, the findings suggest that flood risk management can be significantly improved, leading to better preparation and long-term sustainability for managing natural hazards.

Introduced species have negative effects on amphibian populations by reducing local recruitment and consuming larvae before metamorphosis. Fish can naturally colonize ponds periodically because of flooding and connectivity with river floodplains. However, many fish introductions have been intentional for commercial, recreational, and biocontrol purposes. In southeast Missouri (USA), Ambystoma maculatum will attempt to breed in ponds even if introduced fish (Lepomis spp.) are present. We predicted that fish would have negative effects on salamander oviposition, hatching success and timing, and larval survival. In order to evaluate the effects of introduced fish on A. maculatum across life stages, we conducted pond surveys and a series of mesocosm experiments. Using field surveys, A. maculatum deposited significantly fewer eggs in ponds with fish. In short-term mesocosm experiments, we found that hatching time was not significantly affected by deposition site or fish cues, however, hatching success was lower for eggs deposited in fish ponds. No A. maculatum larvae survived when fish were present, regardless of egg deposition site. Our study is important because we found that, unless a female avoids depositing eggs with fish, one fish species can have profound effects on larval amphibian persistence. Therefore, small-scale fish introductions for recreation can act as a potential source for reduced recruitment and an increased risk of local extinction.

The impact of stormwater drainage and detention ponds on flooding is assessed using statistical analysis and physically based computer simulation of a 45-year case study for a peri-urban catchment. In 1978, the 54 km2 Ouseburn catchment in Newcastle upon Tyne was impacted by the connection of a new 2.1 km2 residential development, directly to the Ouseburn River, via a stormwater drain, which reduced the time to peak and increased flood risk. Further residential developments of 1.6 km2 have been built since 2004, again with separated sewer systems, but this time linked to stormwater detention ponds before draining into the Ouseburn River. Detailed analysis of the data, confirmed with computer simulation, shows that in contrast with the 1978 intervention, these new developments had only a minimal effect on the flows in the Ouseburn River, in fact achieving a small reduction in peak flows for large events. This study assesses the post-construction efficiency of such systems, and we show that the stormwater detention ponds are working as designed.

Abstract. Floods are among the most destructive natural hazards in the world, posing numerous risks to societies and economies globally. Accurately understanding and modeling floods driven by extreme rainfall events has long been a challenging task in the domains of hydrologic science and engineering. Unusual catchment responses to flooding cause great difficulty in predicting the variability and magnitude of floods, as well as proposing solutions to manage large volumes of overland flow. The usage of nature-based solutions (NBSs) has proved to be effective in the mitigation of flood peak rate and volume in urban or coastal areas, yet it is still not widely implemented due to limited knowledge and testing compared to traditional engineering solutions. This research examined an integrated hydrological and hydraulic modeling system to understand the response of an at-risk watershed system to flooding and evaluate the efficacy of NBS measures. Using the Hydrologic Engineering Center Hydrologic Modeling System and River Analysis System (HEC-HMS and HEC-RAS) software, an integrated hydrologic–hydraulic model was developed for Hurricane Matthew- (2016) and Florence-driven (2018) floods across the Little Pee Dee–Lumber River watershed, North and South Carolina (the Carolinas), US. The focus was on Nichols, a small town that has disproportionately been impacted by flooding during these two hurricane events. The present article proposes a methodology for selecting, modeling, and evaluating the performance of NBS measures within a catchment, which can be extended to other case studies. Different NBS measures, including flood storage ponds, riparian reforestation, and afforestation in croplands, were designed, modeled, and evaluated. Hurricane Matthew's flooding event was used for evaluating the NBS scenarios given its high simulation accuracy in flood inundation compared to the less accurate results obtained for Hurricane Florence. The scenario comparison evidenced that large-scale natural interventions, such as afforestation in croplands, can reduce the inundated area in Nichols by 8 % to 18 %. On the contrary, the smaller-scale interventions such as riparian reforestation and flood storage ponds showed a negligible effect of only 1 % on flood mitigation.

Flooding is more common than earthquakes and hurricanes, leaving casualties, infrastructure damage, and economic losses in its wake. The October 2018 floods in Trinidad heightened public concern about the ability of public authorities to manage floods. This study investigates the impact of five combinations of detention basins and embankments on the cost of physical damage to residential buildings in the Caroni River Basin. Further comparison of the maximum flood depth before and after the implementation of structural mitigation combinations was conducted for typical design return periods of 5, 25, 50, and 100 years. The results showed that strategically introducing detention ponds along the Aripo and Guanapo Rivers caused the greatest reduction in flood damage cost (12.86%). Evidence also suggests that attenuation of flood waters by detention ponds is a better alternative to flood protection by embankment-only options

Yogyakarta International Airport (YIA) is a new airport that operates in the Special Region of Yogyakarta, located in Temon District, Kulon Progo Regency. The presence of the airport will undoubtedly bring various benefits, such as increasing economic activities in the area around the airport. However, the location has a problem, namely the risk of flooding. Flooding can affect activities around the airport, such as freight forwarding activities and access to or from the airport. Based on this problem, efforts are needed to prevent the flood that occurs does not have an impact on the activities of YIA airport and the surrounding area. In this case, the researcher used the EPA SWMM program in modeling the drainage system at the site under study. Modeling the point of occurrence of flooding will make it easier to normalize and add embankments to the channel. Modeling with EPA SWMM 5.1 requires input data such as rain distribution data, watershed characteristics, and the transverse appearance of the drainage channel. The results showed an overflow in the 15 drainage channels studied. The causes of overflow are high surface runoff and sedimentation based on channels and backwaters. Efforts to overcome by normalizing and adding embankments are sufficient to overcome flooding in several channels. Meanwhile, for channels that are still experiencing flooding, other countermeasures, such as retention ponds, are needed.

Using geotechnologies has become fundamental for planning the sustainable expansion of agricultural activities, especially fish farming. The objective of this work was to map and carry out the morphological characterization of the hydrographic micro-basins and their physical aspects, such as slope, altimetry, and land use and occupation, and also to quantify and locate the existing excavated ponds in the municipality of Pato Bragado, in Paraná State. Geotechnology tools and images generated by the free software QGIS and Google Earth were used to create maps of the excavated ponds' physical aspects, quantification, classification, and location. The predominant slope in the municipality is gently undulating, and soy plantation uses 42.99% of the municipality's entire area. The mapping located 190 excavated ponds. Depth measurement was not carried out, but rather mapping concerning water depths representing a total area of 47.86 ha of water blade and nine micro-basins within the municipality of Pato Bragado, with only the Arroio Fundo micro-basin covering 47.37% of all existing excavated ponds. The morphometric indicators concluded that the micro-basins present a minimum risk of flooding, which is ideal for use in fish farming. Making the results of this work available to public managers and fish farmers aims to demonstrate the importance of using geotechnologies for sustainable planning to expand aquaculture activities, which, in this case, are focused on fish farming.

The Bula Flood events began in 2016 and continue until the present. Every year, the city of Bula experiences frequent floods, with the peak occurrence usually happening between February and July. Since 2016, the local government has undertaken several structural interventions to address the issue, but the problem of flooding in Bula remains unresolved. The flooding in the Bula area is primarily caused by the overflow of the Kabur-Kabur River. An existing analysis using a 25-year return period discharge (Q25) with HEC-RAS and EPA SWMM models reveals that the flooding primarily occurs along certain sections of the Kabur-Kabur River. The flood management strategies implemented in Bula include the construction of retention ponds, river normalization, and the implementation of an early warning system for floods. The validation analysis of flood control measures using the HEC-RAS and EPA SWMM programs indicates that the flood management strategies implemented for the Kabur-Kabur River are effective in mitigating flood problems in the city of Bula. As a result, the flood control measures being applied can be considered successful and should be continued.

<p>Making cities resilient to natural disasters has become a priority for many policy makers. However, few studies of global cities analyze environmental vulnerability, disaster resilience, or urban flood resilience. This article analyzes global cities’ disaster resilience to flooding: New York City, London, Randstad, Tokyo, Shanghai, and Taipei. Case studies of those global cities will assist cities world-wide to prepare for the future. Results indicate that a hurricane could leave approximately 25% of New York City with severe economic losses by 2050. In London, 15% of the land is located in flood-prone areas. The Thames Barrier began to operate to protect London from flooding in 1982. However, this also encouraged housing development closer to the river, and resulted in higher exposure and vulnerability of flooding. Randstad has approximately 40% of its land areas in flood-prone areas, but Randstad is well prepared for flood risk reduction by land-use and environmental planning. In Tokyo, extensive urbanization suffers from severe damages once flooding occurs. In Shanghai, approximately 50% of its land is in flood-prone areas. Shanghai is the most vulnerable to floods of the coastal cities. Shanghai is still not well prepared in land-use and environment planning for urban flood resilience. In Taipei, flood-prone areas account for approximately 41% of its total land area in an extreme weather scenario. Among these six global cities, Asian cities should focus more on urban flood resilience since most of flooding hotspots by 2025 will be located in Asian nations with having weak policies and actions, inadequate risk information, insufficient budgets and poor implementation capacities (UNISDR 2013). This research suggests that global cities, particularly Asian cities, should promote policies of urban flood resilience, focusing on land-use and environmental planning for resilience as well as strengthening their organizations and funding to reduce disaster risk, maintain up-to-date risk and vulnerability assessment. Urban policies should include environmentally responsible development in the face of continued population and economic growth, and being resilient regarding natural disasters. Cities can also adopt a growth management policy to direct development away from flooding hotspots. Urban regeneration policy should require developers to improve storm sewers, water retention ponds, and permeable surfaces. Planning more space for rivers, more constructed wetlands, and more ecological ponds to accommodate water is important. Cities can promote an actuarially fair flood insurance program which can reflect actual flood risks. A bottom-up community resilience plan would assist achieving urban resilience.</p>

Problem statement. Large accumulators of liquid waste (e.g., mine water ponds, tailing ponds, etc.) are long-term sources that change the hydrological regime. A negative consequence of this process is flooding of the territory. In addition, the infiltration of contaminated water from such hazardous sources changes the quality of groundwater. Therefore, it is important to analyze the impact of such anthropogenic sources on the process of flooding and deterioration of groundwater quality. To solve this problem, it is very important to use the method of mathematical modeling as an effective mean of researching problems of this class, since the use of physical modeling is practically impossible within the scope of problems of this class. The purpose of the article. Development of numerical models for predicting changes in the hydrological regime (flooding of the territory) and groundwater quality under the influence of anthropogenic pollution sources. Methodology. To assess the dynamics of changes in the hydrological regime, a two-dimensional equation of filtration of a non-pressure groundwater flow is used. A two-dimensional geomigration equation (planned model) is used to analyze changes in groundwater quality during infiltration of contaminated water from the settling pond. This equation takes into account the convective transfer of contaminants in the filtration flow, dispersion, and the intensity of contaminant infiltration into the groundwater flow. The method of total approximation is used for numerical integration of the filtration equation. For the numerical integration of the geomigration equation, an implicit splitting scheme is used. Scientific novelty. Effective numerical models for rapid assessment of changes in groundwater dynamics and quality under the influence of anthropogenic sources that change the hydrological regime are proposed. The constructed numerical models take into account a set of important physical factors that affect the process of geomigration and flooding of the territory, namely: filtration coefficient, variable depth of free-flowing groundwater, dispersion, intensity of the source of impurity emission into the groundwater flow. This makes it possible to obtain a comprehensive assessment of the process of flooding and groundwater pollution.. Practical significance. A computer code has been created that allows practical usage of the developed numerical models. This code is an effective tool for theoretical study of non-stationary processes of territory flooding and anthropogenic groundwater pollution. Conclusions. A numerical model for calculating groundwater dynamics has been developed. The model allows to predict the level of groundwater rise under the influence of a man-made source of wastewater infiltration from a settling pond. A numerical model for calculating the process of geomigration from an anthropogenic source of emissions has been developed. The model makes it possible to predict the dynamics of contamination zone formation in a non-pressure groundwater flow. The developed numerical models take into account the most important parameters that affect the formation of flooding zones and groundwater contamination.

Malaysia, being a tropical country located near the equatorial doldrums, experiences the annual occurrence of flood hazards due to monsoon rainfalls and urban development. In recent years, environmental policies in the country have shifted towards sustainable flood risk management. As part of the development of flood forecasting and warning systems, this study presented the urban flood simulation using InfoWorks ICM hydrological−hydraulic modeling of the Damansara catchment as a case study. The response of catchments to the rainfall was modeled using the probability distributed moisture (PDM) model due to its capability for large catchments with long-term runoff prediction. The interferometric synthetic aperture radar (IFSAR) technique was used to obtain high-resolution digital terrain model (DTM) data. The calibrated and validated model was first applied to investigate the effectiveness of the existing regional ponds on flood mitigation. For a 100-year flood, the extent of flooded areas decreased from 12.41 km2 to 3.61 km2 as a result of 64-ha ponds in the catchment, which is equivalent to a 71% reduction. The flood hazard maps were then generated based on several average recurrence intervals (ARIs) and uniform rainfall depths, and the results showed that both parameters had significant influences on the magnitude of flooding in terms of flood depth and extent. These findings are important for understanding urban flood vulnerability and resilience, which could help in sustainable management planning to deal with urban flooding issues.

Kampung Rawa Bamban, Benda District, Tangerang City, is highly prone to flooding due to its flat topography, inadequate drainage systems, and uncontrolled water flow. High rainfall intensifies the issue, leading to prolonged inundation. Flooding results in significant material losses, disrupts daily activities, and degrades environmental quality. Therefore, an effective and sustainable solution is essential. This study aims to evaluate the effectiveness of detention ponds and pump systems as an integrated flood control strategy. The research employs topographic analysis, flood volume calculations, and hydrologic-hydraulic simulations to assess the performance of retention ponds and pumps. The detention pond functions as a temporary reservoir for stormwater runoff, while the pump discharge excess water into drainage channels once the pond reaches its capacity. The results show that the retention pond can store up to 1,208 m³ of stormwater. Based on land availability, the pond is designed with a surface area of 300 m² and a depth of 4 m, supported by a pump with a capacity of 300-liters-per-second. Model simulations indicate that the pond reaches near-maximum elevation at 05:36, prompting triggering pump activation at 05:37. After operating for approximately two hours, the pond is fully drained before 07:00. The combination of detention pond and pump is effective in reducing the flood extent and shortening the inundation duration. This study offers valuable insights for local governments in developing sustainable flood mitigation strategies.

Mangrove ecosystems provide important functions for ecosystem service. However, the degradation of mangrove forests, especially conversion to aquaculture ponds is a driver for deforestation. Therefore, this study aimed to analyze the mangrove vegetation and duration of inundation in ponds before and after rehabilitation activities were conducted on abandoned ponds. In this analysis, we used the census method to collect structural data, the Important Value Index (IVI), composition and structure, and the diversity index. To determine the duration of inundation at the observation sites in a pond in Tanjung Rejo, Percut Sei Tuan village, we deployed one water logger and two Mini Buoys at ponds. At the observation site, eight pure mangrove species have been founded, namely Avicennia alba, A. marina, Bruguiera gymnorrhiza, Excoecaria agallocha, Rhizophora apiculata, R. mucronata, R. stylosa, and Nypa fruticans. The main species was A. marina which is a total of 756 idv/ha at the seedling stage 52.81 idv/ha at the sapling stage, and 268.09 idv/ha at the tree level. The highest IVI has founded in seedlings, saplings, and trees at A. marina, which was 99.30%. 80.41% and 94.49%, respectively. Rehabilitated Avicennia spp that grew only 2.4% from 2000 seedlings. The low growth of seedlings was influenced by the pond condition which was always in a state of flooding. The current study provides important information that in carrying out planting or rehabilitation activities it is necessary to determine which inundation rotation should be a priority considered.

Water runoff is temporarily stored in retention ponds as part of a flood control scheme to avoid major floods. There are currently a number of retention ponds in Palembang City that work to reduce flooding during rainy seasons. Land use is expanding, and water catchment areas are getting smaller as a result. The feasibility of constructing a retention pond in Palembang City's Sukarami District is discussed in this study. The usability, hydrology, and physical environmental aspects of data analysis are the main areas of study. The study of hydrological aspects indicates that the planned retention pond has an area of 6.55 Ha and is capable of accommodating a large water discharge of 0.294 - 0.466 m3/sec for a return period of 50 years. The research also demonstrates the benefits of collecting rainwater runoff and improving environmental aesthetics. The construction process and the presence of this retention pond will have an impact on environmental quality, according to the findings of the study of physical environmental elements.

AbstractMales of the South American treefrog Aplastodiscus perviridis construct concealed subterranean nests. Using a complex courtship behavior that involves tactile stimuli and vocalizations, males guide the females to the subterranean nests where eggs are laid. Embryos and facultatively oophagous tadpoles (at least in stage 25) stay in subterranean nests until flooding transports them to ponds or streams. This is a rare reproductive mode previously known for few species in the Hyla albosignata and H. albofrenata complexes. Based on similarities of reproductive mode we suggest a monophyletic origin for Aplastodiscus and these complexes of Hyla.

The melting of polar ice caps due to climate change has resulted in sea level rise that threatens coastal areas, such as the Demak Regency. The impact of tidal flooding is, exacerbated by land subsidence. This study aimed to map and predict the distribution of tidal flooding in coastal Demak and its impact on land use. The methods used included Differential Interferometry Synthetic Aperture Radar (DInSAR) for Land Subsidence (LS), supervised classification for land use, admiralty for tides, data visualization for elevation, linear regression analysis for SLR, meteorological data analysis for wind and rainfall, and spatial analysis for tidal flood inundation mapping. The results showed an LS rate of 2,74 cm/year, highest tide height of 61,93 cm, average elevation of 1,893 m above sea level, SLR rate of 0,435 cm/year, wind speed of 0,5-5,7 m/s blowing from the northwest, and average daily rainfall of 7,476 mm. The tidal flood inundation area in 2023 reached 8.954,6 hectares and is predicted to reach 11.394,5 hectares in 2031. Tidal flooding affects mangroves (523,6 hectares), ponds (3.857,9 hectares), settlements (1.095,4 hectares), industries (3.453,00 hectares), and rice fields (24,7 hectares).

<p>This article interprets the perception and aspirations of the city community, as a cornerstone of drafting the design criteria of a community-based city park landscape, which is effective and sustainable. Flooding and drought problems in Jakarta and surrounding areas should be resolved in a comprehensive, integrated and sustainable manner. Referring to the Water Sensitive Urban Design (WSUD) which is an innovation in integrated water management, it is recommended to develop the function of detention and retention ponds as part of storm drainage system, replacing conventional system. Development of the city park landscape criteria as the synergies of the RTH function and the detention/retention ponds should be approached in a very careful, avoiding fatal malfunction and harsh rejection of the user community. The best approach should be done through tracing the needs, desires and expectations of the city community as the ‘end user' as well as 'super client' of the city park. Research on the perception and aspirations of the city community on the idea of the development of City Park with the role of retention/retention ponds has been conducted between February to May 2020 in Jabodetabek. <strong></strong></p>
