Abstract: A method of calculation of ice jam backwater is put forward by reference of bed-load transport theory and the calculation result of ice jam in the reach between Yanguoxia to Liujiaxia of Yellow River. The characteristics of experiential parameters with boundary condition are presented via calibration the ice jam water surface profile of Wanjiazhai reach, based on mesaured data. The ice jam water surface profiles of Haibowan reservoir forecast.

Key words: ice jam forecasting, Haibowan Reservoir, the Yollow River
