In arid regions, the construction of hydraulic structures is relevant due to shortage water resources. Using example Pskov hydroelectric power station, results calculation end structure energy spillway, made in form a well unique design, are presented. A culvert wall, with an initial expanding part and sloping spillway forming oblique forms well. The depths speeds each parameters jump calculate...

Close to the border with Sudan, Ethiopia is currently building the largest hydroelectric power plant in Africa with a storage volume corresponding to approximately 1.5 years of the mean discharges of the Blue Nile. This endeavor is controversially debated in the public and the scientific literature. Contributing to this discussion, by shading some light on climate change issues, an eco-hydrolog...

We investigate of a special dam optimal location at the Volga river in area of the Akhtuba left sleeve beginning (7 km to the south of the Volga Hydroelectric Power Station dam). We claim that a new water-retaining dam can resolve the key problem of the VolgaAkhtuba floodplain related to insufficient water amount during the spring flooding due to the overregulation of the Lower Volga. By using ...

A comparison analysis based method for computing the water consumption volume needed for electric energy production of optimal scheduling in hydro-thermal power systems is presented in this paper. The electric energy produced by hydroelectric plants and coal-fired plants is divided into 4 components: potential energy, kinetic energy, water-deep pressure energy and reservoir energy. A new and im...
