Engineering protection of reservoirs of hydropower developments from flooding and subirrigation

Abstract

1. Flooding and subirrigation of lands is the determining factor of all ecological changes in the zones of hydrostation reservoirs. 2. An analysis of the specific land-use intensity of different power stations shows that at present there is a tendency toward a reduction of the difference of this index for hydroelectric stations, on the one hand, and thermal power stations (nuclear power stations), on the other. 3. For protection and conservation of lands and improvement of the ecological state of streams, reservoirs, and the lower pools of hydro developments calculation methods (algorithms and programs) have been developed for substantiating the optimal parameters of the embankment systems taking into account the effect of the latter on the functioning of hydroelectric stations, other participants of the water-management complex, and the environment.
