RESEARCH ON WAVE ACTION ON LAKE SHORES AND UNLINED SLOPES OF ARTIFICIAL EARTH STRUCTURES

A.A. Pichoughkin

Abstract


The construction of big modern hydro-electric plants makes it necessary to create large reservoirs, of which the surface area can be on the order of some hundreds or even thousands square kilometers. As for example, the surface area of the Kuibyshev reservoir is 5600 km 2 that one of the Sherbakov reservoir - 4500 km^, of the Stalingrad reservoir - 3470 km2, of Kahovka reservoir - 2155 km2. The dimensions of reservoirs in plan being so considerable, the waves of 3-3,5m height can appear on the water surface. The shoreline of reservoirs created on U.S.S.R. plain rivers exceeds the length of 13000 km. The problem of the protection of the upstream slopes of artificial earth structures and natural shores against wave action is of extreme importance under these conditions.
