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...

abstract: water quality of dam storage is highly affected by upstream environment and basin. regarding other conducted studies, there exist various reasons such as some studies and general monitoring of dams which cause some main problems including salinity, chemical and microbial pollution eutrophication, and sedimentation. chame-gardalan storage dam in ilam province is one of the storages whi...

The present work has been carried out because nobody has done the hydrological properties assessment of the water of this Sawangi Nullah Dam, and to create the knowledge about the quality and potability of the water in the village people. This dam is situated near Hingna M.I.D.C. about 34 Kms from Nagpur city. The water samples were collected for a period of 12 months from June 2009 to May 2010...

The future Surface Water and Ocean Topography (SWOT) satellite mission will provide twodimensional maps of water elevation for rivers with width greater than 100 m globally. We describe a modeling framework and an automatic control algorithm that prescribe optimal releases from the Selingue dam in the Upper Niger River Basin, with the objective of understanding how SWOT data might be used to th...

The temporal migration patterns of European glass eel Anguilla anguilla at the Couesnon estuarine dam (Mont-Saint-Michel Bay, France) were examined in winter and spring 2004 and 2005. The dam which is located close to the river mouth constitutes a major obstacle for upstreammigrating glass eels. The migration was observed at different temporal scales, from within individual tides to complete ti...

Riverine dams alter both the physical environment and water chemistry, thus affecting species assemblages within these environments. In the United States, dam construction is on the decline and there is a growing trend for dam removal. The Choctawhatchee, Pea, and Yellow Rivers Watershed Management Authority had initiated the permitting process for placing a reservoir dam on the Little Choctawh...

SYNOPSIS. The leakage of water from a dam suggests a number of possible scenarios, and none of them are good. At best, the reservoir owner is losing the power-generating potential of the escaping water. At worst, the leakage may be the precursor of dam failure. Among the technological advances that will enhance the safety and efficiency of hydropower in the future, is a remarkable breakthrough ...

Dam outflow elements, with hybrid behavior characterized by: • Continuous variables with time dependency: water level, water released, etc. • Discrete variables: opening degree of the outflow elements. Developing a Decision Support Tool for Dam Management with SPIN María-del-Mar Gallardo1, Pedro Merino1, Laura Panizo1 and Antonio Linares2 1Dept. Lenguajes y Ciencias de la Computación. Universit...

Planning for supply water demands (drinkable and irrigation water demands) is a necessary problem. For this purpose, three subjects must be considered (optimization of water supply systems such as volume of reservoir dams, optimization of released water from reservoir and prediction of next droughts). For optimization of volume of reservoir dams, yield model is applied. Reliability of yield mod...
