Risk assessment of cascade reservoir dams is not only the key to ensure safety basin, but also objective requirement dam risk management. Based on development status reservoirs in China, complexity management compared with a single was analyzed. By reviewing advances studies reservoirs, this paper summarized their limitations terms scientificity and practicability. Moreover, some concepts metho...

Four aquatic ecosystems (two rivers and two dams) situated in the western part of Bulgaria were investigated over a three years' period. The River Egulya and Petrohan dam are situated in mountainous regions at about 1000 m altitude, and are not influenced by any anthropogenic sources. Petrohan dam is a site for long-term ecosystem research as a part of Bulgarian long-term ecological research ne...

In developing countries, large dam projects continue to be launched, primarily to secure a time-stable fresh-water supply and to generate hydropower. Meanwhile, calls for environmentally sustainable development put pressure on the dam-building industry to integrate ecological concerns in project planning and decision-making. Such integration requires environmental impact statements (EISs) that ...

River scientists strive to understand how streamflow regimes vary across space and time because it is fundamental predicting the impacts of climate change human activities on riverine ecosystems. Here we tested whether flow periodicity differs between rivers that are regulated or unregulated by large dams, dominant periodicities over in response dam regulation. These questions were addressed ca...

Reservoirs are principal water resources that supply irrigation water to paddy fields and play an important role in water resources management in South Korea. For optimal irrigation reservoir operation and management, it is necessary to determine the duration of irrigation water shortages. Management of reservoir operation and irrigation scheduling should take into consideration essential varia...

Reservoir sedimentation is a worldwide problem affecting sustainable storage use as well as sediment transport downstream of dams. Various techniques are applied for sediment mitigation, among which, venting of turbidity currents. This paper reviews, discusses and evaluates venting of turbidity currents based on an experimental approach. Data acquisition during the tests is accomplished using f...
