Abstract Drainage ponds are a useful measure to manage water resources. However, these small water bodies are characterized by highly dynamic internal processes. This article discusses a simple process-oriented model developed to simulate temporal dynamics of internal processes within drainage ponds. The PondR model is able to simulate the relevant hydrological processes of the pond by using commonly available input data. For model development, data from a 3-year monitoring campaign of the investigated drainage pond served to validate the newly developed model for the autumn and winter time periods. A temporal parameter sensitivity analysis (TEDPAS) revealed that groundwater parameters are predominant during the whole year. The model performed well in simulating outflow together with simulated pond volume and improved the understanding of the hydrological regime for drainage ponds. Regarding the practical benefit, the developed PondR model could be useful in future studies for more precise planning of pond dimensions and water resource management in the field of research and engineering services.

Abstract One of regency in West Sulawesi Province that has vast area of brackishwater ponds is Mamuju Regency. However, there is not yet information on pond management that conducted by farmers in Mamuju Regency. Hence, it was carried out a research that aim to know pond management factors that effect on the pond productivity in Mamuju Regency. Survey method that applied to find primary data and ponds production also pond management by means of questionnaires. The dependent variable in this research was total production, while the independent variables were pond management factors that consists of 30 variables. Multiple regressions with dummy variable were used to analyze the data in predicting total production. The results show that total production of brackishwater ponds in Mamuju Regency is 349.5 kg/ha/season in average. There are seven pond management variables that effect on total production in Mamuju Regency i.e. stocking density of milkfish, stocking density of tiger prawn, out-break disease, initial liming, duration of milkfish culture, initial pest control with teaseed and size of tiger prawn that stocked in the brackihswater pond. The total productivity of brackishwater pond can be increase through increasing dosage of initial liming, increasing duration of milkfish culture, increasing dosage of teaseed as initial pest control as well as increasing size of tiger prawn that stocked in the brackishwater ponds.

Receiving water quality concerns associated with increased construction activities in recent years in the Greater Toronto Area has prompted the Toronto and Region Conservation Authority (TRCA) to evaluate design criteria for sediment control ponds employed during the construction period. Stormwater management ponds located in the towns of Richmond Hill and Markham were monitored to obtain stormwater runoff quantity and influent-effluent quality data during site development. The ponds were designed and constructed in accordance with the Ontario Ministry of the Environment Stormwater management planning and design manual 2003 for an enhanced level of protection (i.e., 80% total suspended solids removal). A hydrodynamic and sediment-transport model was used to examine the effect of pond geometry on sediment removal efficiency under varying storm events. The monitoring data and the modelling results clearly demonstrate the importance of proper pond size and geometry design. This paper focuses on the effect of the ratio of pond length to pond width in minimizing the short-circuiting effect and improvement of the sediment removal efficiency of stormwater management ponds. The results of this study will be useful in updating the design criteria for stormwater management ponds.Key words: stormwater, management, pond, design, sediment.

Abstract An investigation into phytoplankton and periphyton algal communities of two recently constructed Stormwater management ponds suggests that Stormwater impacts on biological communities are reduced during passage through the ponds, providing a degree of protection for biological communities in their receiving waters. In both ponds, disturbance effects from the incoming Stormwater on algal community richness and evenness appear to be greatest in the sediment forebay and are reduced in the main pond. However, the nature of the disturbance in the two systems can be seen to be fundamentally different from a biological perspective, with Rouge Pond functioning primarily to reduce toxins harmful to algal communities (e.g., heavy metals), and Harding Pond acting to reduce nutrients. The taxonomic composition of the two sites provides an indication of the quality of the incoming Stormwater. Rouge Pond, which contains many marine and brackish water species, receives Stormwater runoff from a major highway, while Harding Pond, containing more nutrient rich species, receives Stormwater primarily from residential properties. Despite the nutrient-rich conditions present in both ponds, nuisance blue-green algae (cyanobacte-ria) are conspicuously absent, and the ponds appear to have little potential for developing harmful algal blooms. The lack of blue-green algae can be linked to the hydraulic functioning of the ponds, suggesting that Stormwater facilities may be engineered to inhibit undesirable algal communities.

Full textAbstract:
Simpang Polda retention pond is an alternative flood control construction which is designed to temporarily hold exceeding water flow during rainfall in the vicinity of Simpang Polda, in order to avoid or reduce flood in the area. Retention ponds are prone to sedimentation due to garbage and other materials settling down in the bottom of the pond, which in turn causing reduction of total volume of water it can contain. To ensure that the pond has enough volume, depth measurements were done so that the pond can function as intended. Boat robots from previous research in 2019 and 2020 were utilized as the method to measure the depth of the retention pond. The boat robots mapped the depth of the whole pond area with the help of remote control and single beam sensor. Measurement result shows that the Simpang Polda retention pond has an average depth of 2.245 m. Based on this finding it is suggested that the local government water resource management agency (Dinas PUPR Dept. PSDA) to follow up with the appropriate sediment removal procedures to return the pond’s depth back to the original value when it was constructed

The objective of this work was to evaluate the effect of pond management on fish feed, growth, yield, survival, and water and effluent quality, during tambaqui (Colossoma macropomum) juvenile production. Fish were distributed in nine 600 m² earthen ponds, at a density of 8 fish per m²; the rearing period was 60 days. Three different pond management were applied: limed and fertilized (LimFer), limed (Lim), and natural (Nat). Fish were fed with a commercial ration containing 34% crude protein three times daily. There were no significant differences in fish growth or yield. Three main items found in tambaqui stomach were insect, zooplankton and ration, without a significant difference among treatments in proportion. Alkalinity, hardness, and CO2 were greater in LimFer and Lim ponds. Chlorophyll a, transparency, ammonia, nitrite, temperature, and dissolved oxygen of pond water were not significantly different among treatments. Biochemical oxygen demand, total phosphorus, orthophosphate, ammonia, and nitrite were significantly greater in effluents from LimFer ponds. Pond fertilization should be avoided, because growth and yield were similar among the three pond management systems tested; besides, it produces a more impacting effluent.

Universitas Indonesia (UI) has a campus in Depok with six ponds, five of which are artificial ponds and one of the catchment area that operates in the central Ciliwung Sub-watershed. The ponds (Kenanga, Agathis, Mahoni, Puspa, Ulin and Salam "KAMPUS") are designed as one of the catchment area, referring to Presidential Decree No. 32/1990 about the management of protected areas, ponds as catchment areas, flood controllers, and groundwater runoff. However, due to uncontrolled development in the catchment area of the UI pond system, KAMPUS cascade ponds transformed into a "toilet" which accommodates the liquid and solid waste of its catchment area. The mechanism designed for management in the KAMPUS cascade pond system is to utilize the cascade pond as a stabilization pond (improving water quality). One of them is utilizing Agathis cascade pond as a constructed stormwater wetland system, which is a pretreatment for the inflow to the KAMPUS pond system. This constructed wetland design is planned with several mechanisms: precipitation, filtering, chemical process by utilizing plants for absorption, nutrient transformation and eliminating pathogens. The result shows that this constructed wetland gives the water quality improvement percentage up to 87%. Water quality on effluent conforms with the water quality standards for irrigation and planting (grade 4) referring to Government Regulation No. 82/2001 about Water Quality Management and Pollution Control.

Marginal and small farmers of the state of West Bengal suffer from frequent droughts due to erratic rainfall patterns, high evaporation rates, and recurrent water scarcity. The majority of farmers in West Bengal have farm ponds that are grossly underutilized due to several social and technical constraints. In this study, the roles of various socio-economic factors on management of existing farm ponds were examined using a binary logit model to understand their contributions to sustainability of the livelihoods of marginal and small farmers of the region. A field survey of 155 farm ponds, owned by farmers with different socio-economic backgrounds, was undertaken in Kharagpur Blocks (I, II) of West Medinipur district in West Bengal. The study also included water budget, water quality, and economic analyses of three farm ponds having different management practices, viz. managed bentonite lined pond, managed unlined pond, and unmanaged unlined pond. Water budget analysis revealed that about 610 mm of extra water depth could be saved in bentonite-lined ponds compared to unlined ponds. Also, the water quality (as per the threshold values recommended for aquaculture life) was not deteriorated due to bentonite lining. The study suggested that the best way of utilizing pond water includes simultaneous water use for irrigation and fish cultivation, which is possible with lined ponds. Therefore, lined farm ponds with locally available cheap lining material might be a suitable intervention in the context of the socioeconomic development of small and marginal farmers of the Kharagpur region. The pond management was significantly influenced by household economic factors and pond related factors.

The open mining method has the potential for the formation of mine water. Mine water is characterized by a high degree of acidity which affects the life of organisms and the quality of the environment indirectly or directly, therefore it needs to be managed. This study examines mine water management at PT Adaro Indonesia. The methods used in the research were field studies and laboratory experiments. Grab sampling is used to take water samples, with the test parameters being pH, Fe and Mn metals and total suspended solid (TSS). Data analysis was carried out quantitatively and descriptively. The mine water management used is in the form of a settling pond. The settling pond consists of several compartments, namely sedimentation pond, safety pond, treatment pond and mud pond. The quality of mine water management through a series of settling ponds obtained changes in pH to 6.07, Fe metal 0.0465 mg/l, Mn metal 1.3513, and TSS 35 mg/l with an efficiency of more than 50%. The quality of mine water produced after going through management has met the established regulations, namely Decree of the Minister of Environment and Forestry No. 1347/MENLHK/SETJEN/PLA.4/12/2022.

The increase in aquaculture businesses in the coastal areas of Seruway District, Aceh Tamiang Regency, has resulted in high conversion of mangrove forests into ponds. If management is not carried out, it will have an impact on coastal environmental degradation. Therefore, it is necessary to look for a sustainable pond management model. One model is silvofishery. In developing this silvofishery model, biophysical environmental data, social and economic conditions of pond cultivation are needed. The aim of this research is to determine the biophysical, social performance, income level and feasibility of a silvofishery system pond business. The research was conducted using descriptive methods with survey techniques. The research results show that the silvofishery ponds at the research location use a partite pond model. From the analysis of biophysical properties, overall results were obtained, the conditions were suitable for the development of milkfish and tiger prawn cultivation. From social performance, the results showed that silvofishery system pond farmers are still of productive age and have an average pond area of 5 ha. The income obtained from silvofishery system ponds is IDR 19,560,000/ha/year/farmer. Silvofishery pond system If the R/C value is greater than 1, then silvofishery pond farming is worth pursuing.
