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...

The Three Gorges Dam, located in the largest endemic area of schistosomiasis in China, is one of the world's largest hydroelectric projects to date. Some large-scale hydro projects have resulted in schistosomiasis emergence or re-emergence. Therefore, the dam's potential impact on the transmission of Schistosoma japonicum has raised concerns from medical researchers worldwide. A systematic lite...

safety of a dam depends upon not only design and construction but also on the monitoring at the early years after impoundment. shahr- chai dam is located on the shahr- chai river and 12 km away from urmia city in the south- west. the construction of dam was ended in winter 2004, and then both of the dam impoundment and monitoring instrument readings were started, immediately. after ending dam c...
