Abstract: The reservoirs created by low-head river dams are seldom large enough to store entire ice-carrying flood waves arriving from the upstream river sections. For this reason, provisions must be made for passing the ice through the reservoir. Normally an open strip is cut by means of icebreakers in the ice cover of the reservoir and the broken ice, together with the running ice arriving from the upstream river sections is released through the weir. In such cases the unbroken ice cover is required to remain stable. The related problems have been investigated in the hydraulic model of the Dunakiliti Dam and the conclusions derived therefrom are presented.
