Abstract：The model recommended in this paper is based on the study of regulating effects and operating rules of each large-to-middle sized reservoir and a group of small reservoirs(including ponds).It has been used to forecast floods.For the Fengshuba basin，located in the southern part of China，this model yields a qualified rate that raises the previous flood forecasting accuracy from 85.1%to 91.7%.
