P. 283-285Abstract: The first 2D computer model of the currents (including circulation currents) inside the glacial dammed Kurai Lake under its release caused by the dam break is simulated in the RMA2 program of the SMS 9.2 modeling system. The hydraulic parameters are calculated for several given water discharges in the transit flow (from 10 to 0.3 million m3/s) of the basin. A consecutive change in the circulation currents during the release of the lake is identified. A comparison of the character of circulation and the calculated fields of the depths and the current velocities in the lake with the orientation of the gravel ranges on the bottom of the Kurai basin allows reconstruction of the hydraulic conditions of possible formation of the giant ripple fields.
