Abstract: The Yimin River, situated from 119°10' to 121°01 east longitude and from 47°40 to 49°05 north latitude, is a branch of Eerguna Water system. The ice in the river is broken by the action of hydraulic and mechanic forces. So that the ice broken process begin by the action of the thermal force and by the action of hydraulic force. A linear relation between the absorbed heat action and the stage of the river or the discharge rise coefficient is gotten by calculating the absorbed heat amount, there is anorth lineal relation between rise coefficient and the days which is from the date on which the river discharge is larger than the frozen discharge to the date on which the river thaws. The maximum discharge and the highest stage in the river can be calculated by using the rise coefficient and the days.
