Abstract: River ice is natural phenomena in the northern of China under specific conditions of meteorology, geomorphology and hydraulics. The ice-related problems often makes the function and management of structures or channels very difficult. In this paper a twodimensional river-ice numerical model under boundary-fitted coordinate is developed to accurately simulate complicated boundary condition. The numerical model consists of hydraulics model, flow temperature model, frazil-ice distribution model, and ice transportation under ice cover. MacCormack scheme is used to solve the equations. The model is validated with field data on the Hequ Section of Yellow River.
