The article describes the definition of filtration flow gradients in dam's body on example Kattakurgan reservoir, analysis reasons for their change cross-section. Evaluation aggressiveness plays an important role ensuring stability reservoir dam and its parts. To assess body, it is necessary to know action pattern water effect elements dam. In addition, chemical composition piezometers was anal...

INTRODUCTION Bioecological aspects of anophelines (Diptera: Culicidae) near areas under the direct influence of the hydroelectric plant reservoir of Serra da Mesa in Goiás, Brazil, were analyzed. METHODS Samples were collected at the surrounding dam area during the phases before and after reservoir impoundment. The influence of climatic and environmental factors on the occurrence of Anopheles...

The paper presents a study on developing an optimum reservoir release policy by using ABC algorithm. The decision maker of a reservoir system always needs a guideline to operate the reservoir in an optimal way. Release curves have developed for high, medium and low inflow category that can answer how much water need to be release for a month by observing the reservoir level (storage condition)....

Environmental restoration is not simply a practical matter. The topic carries with it immense of metaphysical and aesthetic interest. In the same way that the science of ecology and cultural phenomenon of environmental politics are inseparable, restoration of the environment is inextricably tied to and informed by several areas of discourse: ecology, cultural ecology, human ecology, environment...

The variation of water velocity in an artificial dam reservoir is influenced not only by the inflow discharge, but also bathymetry and level at dam. depiction spatially complex variations flow through a would be possible without use hydrodynamic models. A reliable model effective tool for predicting analyzing changes geoecosystem age changing climate risk stress. depth-averaged two-dimensional ...

Eroded sediments from catchment areas transport by streams and deposit in downstream less steep areas. Despite reducing the useful life of various hydraulic structures including reservoir dams, flood walls, and bridges, this phenomenon changes the main river hydraulic conditions and increases the flood prone farms in the riverbank area. Check dams are among the structures that can prevent form ...

the present study was carried out to determine the possible origins of sediments entering taleghan dam in northern part of iran, in order to avoid further sedimentation and helping in extension of the useful life of the proposed dam. this was performed by xrd analysis. to do so, first of all, sediment sampling points were positioned along the taleghan river. the collected samples, after coding,...

Leakage is a major safety issue that, if left unchecked, may result in dam failure by various mechanisms. There is enormous pressure on dam operators to repair leaks without significant delays. Frequently, the need to reduce the risk of failure or control water loss has led to costly remedial repairs that are planned and executed without a complete understanding of the problem. A lack of approp...
