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 pe

An investigation was carried out during the rainy period in six semi-intensive production fish ponds in which water flowed from one pond to another without undergoing any treatment. Eight sampling sites were assigned at pond outlets during the rainy period (December-February). Lowest and highest physical and chemical parameters of water occurred in pond P1 (a site near the springs) and in pond P4 (a critical site that received allochthonous material from the other ponds and also from frog culture ponds), respectively. Pond sequential layout caused concentration of nutrients, chlorophyll-a and

Although some methods for determining lime requirement of pond soils are available and commonly used, there is still no consensus on whether it is more effective to apply liming materials to the bottoms of empty ponds or to wait and apply them over the water surface after ponds are filled. There is also little information on how deep lime reacts in pond sediment over time, and whether the depth of reaction is different when liming materials are applied to the water or to the soil. Therefore, three techniques for treating fish ponds with agricultural limestone were evaluated in ponds with claye

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 utiliz

Ponds are small reservoirs located in irrigated areas that allow farmers to capture rainfall, store surplus water from irrigation canals and conserve water from other sources. These ponds allow the users to obtain water on-demand providing built-in flexibility by storing water close to water users. Though ponds have been used widely in irrigated areas for many years, a recent increase in the construction of ponds because of growing water shortages and government policies are placing greater need on understanding their role in sustaining crop production.

The study measures the relationship between physico-chemical variables with the cell density of phytoplankton in nursery, growout and broodstock ponds of fish. This study was conducted at Natore Government Fish Farm in Bangladesh from January to June, 2012. The observed physico-chemical variables like water temperature, transparency, dissolved oxygen, pH, ammonia-nitrogen, total alkalinity and total hardness were found within the standard ranges. Phytoplankton belonging to bacillariophyceae, chlorophyceae, cyanophyceae and euglenophyceae were found among the ponds but euglenophyceae with highe

ABSTRACT: Aquaculture also known as fish farming is one of the methods for breeding rearing and harvesting of freshwater and marine species of fish and shellfish, in ponds, rivers, lakes and oceans. In this article an attempt has been put forth to study and apply techniques that could help in improving the water quality in aquaculture ponds and to further understand the role played by enzymes and probiotics by means of bio remedial procedures and protocols. Aquaculture productivity needs to be improved to cater the ever-increasing demand, no doubt, but simultaneously a proactive role for envir

Based on the data collected in January, March,July and October in 2013, the characteristics of water quality in temporally and spatially in the ponds of Lv-Tang-River national urban wetland park were investigated. The results show that the main pollutants of Lv-Tang-River wetland are chemical oxygen demand, total nitrogen and ammonia nitrogen. Their average concentrations are worse than the national quality standards for Class V. The characteristics of water quality in spatially are significantly correlated with the plant configuration in the wetland. The water quality in reed pond is the best

Introduction: Shrimp has great potential to be used as a business field in Indonesia. Especially in Parigi Regency itself, there are now many shrimp ponds that can be found because of the benefits obtained, so people are interested in making shrimp farming a livelihood. One of the main problems of shrimp ponds is pond water quality. There are several factors that affect pond water quality, namely water temperature, water pH, and water salinity, good pond water quality management can maintain quality standards and can increase shrimp yield and productivity Method: To facilitate the shrimp farme

Abstract. In the Ferlo Region in Senegal, livestock depend on temporary ponds for water but are exposed to the Rift Valley Fever (RVF), a disease transmitted to herds by mosquitoes which develop in these ponds. Mosquito abundance is related to the emptying and filling phases of the ponds, and in order to study the epidemiology of RVF, pond modelling is required. In the context of a data scarce region, a simple hydrologic model which makes use of remote sensing data was developed to simulate pond water dynamics from daily rainfall. Two sets of ponds were considered: those located in the main st

Reservoirs and ponds belong to specific objects of water resources. Most reservoirs and ponds are of anthropogenic origin. They are of special importance for the Lviv region due to its terrestrial properties. In modern conditions, the importance of reservoirs and ponds is growing significantly. This is due to the fact that in many areas they form nuclei around which recreational complexes are formed. Reservoirs and ponds play an important role in the health and recreation of people.

Freshwater fish farming is currently booming in Indonesia, and many use small ponds for efficiency or due to limited location, this can be a problem due to Indonesia's hot climate. Small ponds with not much water volume will cause the water temperature to rise more easily on hot days, of course this is not good for the fish colonies in it. To prevent temperature rise, farmers generally irrigate ponds with fresh water to stabilize the water temperature. Due to the unpredictable weather in Indonesia lately, it will be difficult for farmers to monitor their ponds manually, so a tool is needed tha

Here, we first describe the communities of water beetles and water boatmen in Faroese ponds and, secondly, assess whether community compositions are driven by habitat characteristics or dispersal abilities of species.
