【 摘 要 】

Mountain flood in small watershed comes unexpectedly, and the determination ofwater index is hard. Combined with the actual situation of Miaoxia Watershed, this paper proposes a design of flood calculation method based on HEC-HMS distributed model, and determines mountain flood warning index by using the method of water level backstepping discharge. The result calculated by this paper's method has little difference compared with those using rational formula or instantaneous unit hydrograph, and the determination of the warning index is basically reasonable. The applied results shows that the determination of mountain flood warning index based on distributed hydrological model is simple and feasible, which is consultative for mountain flood warning index selection.
