This paper reviews the environmental impacts of hydroelectric development on fish in China. It describes the hydrological changes and the primary, secondary and tertiary impacts on fish. 4 large hydroelectric projects in central and eastern China
into the overall cumulative effect on fish resources of China's massive hydroelectric development plans.

This article asserts that Bhutan's future economic development depends on selling hydroelectricity to India and Bangladesh. The country's four major river systems have a total potential of generating 16.6. billion KWh of energy per year. However

CBP has resulted in an intertwined system of water diversion, capture, storage, movement, and use for hydroelectric production and irrigation. It transformed the arid environment of central Washington. The CBP morphed over time as values
considerably altered by hydroelectric dams, flow diversions, gravel mining, and construction of streambank protection structures. To document these changes, a historical analysis was performed using maps and aerial photographs. In several reaches the planform
The aim of this research is to assess the impacts of both natural and anthropogenic factors, ranging from climatic variability and change to the influence of river flow regulation resulting from hydroelectric power generation at the headwaters
This article examines the energy requirements of a subsistence economy population in Kigoma Region in North-west Tanzania. There is an urgent need to find alternatives to firewood and the author suggests to develop hydroelectric power.
The brown trout (Salmo trutta L.) in the Mislinja River is endangered because of small hydroelectric power plants. The AA. conducted a sampling of the brown trout, measured the length and weight of caught specimens and analysed the obtained data
, e.g., biomass, abundance, average weight, average length and number of captured brown trout. They discovered that the population of the brown trout has decreased in all the sections where water has been taken away for small hydroelectric power plants
Changes of geometry of Austerdalsisen between 1982 and 1987 illustrate the importance of the calving boundary condition in driving glacier flow. Understanding calving is important for management of hydroelectricity power generation schemes
The Columbia River Basin is the site of a conflict over two resources : hydroelectricity and Pacific salmon. Since 1982, the Pacific Northwest Power Planning Council has endeavored to mediate the conflict by implementing a water budget measure
aim of this work is to achieve a better understanding of the role of hydrology in the Mackenzie Delta ecosystem, in order to predict the impact of environmmental change such as rising sea level, climate change, hydroelectric development, or contaminant
