Forecast of rock streams impact on storage reservoir volume

Abstract

Water storage filling/ activities rock streams and rock fields development. The latter's influence on the reservoirs volume depends on two opposite processes. A basin volume decreases due -to its filling with rock debris brought by mass movement process, with thin particles washed from under the rock fields and with ice rafted blocks. At the same time the volume increases as a result of ice melting from submerged rock fields and subsequent blocks collapse. From the author's calculations follows that the water storage reservoir of the Kolyma Hydroelectric Power Station will somewhat increase its volume due to its interaction with the rock streams.
