| 摘 要： | 以长江上游寸滩-宜昌河段为研究对象,建立了考虑区间降雨的河道洪水预报BP神经网络模型,论证了应用人工神经网络模型进行洪水预报的可行性。以1982年至1986年的洪水预报作为仿真,表明该模型能较好地反映区间降雨的影响,对大中小各种洪水过程都能进行准确预报。

| Abstract: | With BP artificial neural network, a model is developed to forecast flood propagation in Cuntan-Yichang reach of Yangtze River. In the model, local inflow from the rainfall in the catchment between Cuntan-Yichang was considered. Comparison between computed result and measured data from 1982 to 1986 show that the model can simulate the flood process at Yichang correctly, especially, to some representative discharge, which proved the feasibility of this model. |
