Abstract: The cold region river forms a large quantity of frazil slush during winter period. In early March, the solid ice cover partially melts and remains along both sides of the river. Authors detect new phenomena, the discharge shows a daily oscillation in early March through field survey during 1992-1994 in the Penke-niupu River. This paper aims at analyzing physical mechanisms of such a daily oscillation and building its prediction model. Simulation results of the step-pool model considering anchor ice showed good agreement with the observed discharge.
