BPPR网络模型在寸滩站洪水预报中的应用

Application of BPPR Network Model to Flood Forecasting of Cuntan Station

以寸滩站为例，针对建立复杂区间入流河段洪水预报系统是水文预报领域的难点、峰值预报精度是洪水预报过程的关键，采用BPPR网络模型，构建了寸滩站BPPR洪水预报模型，并预报了寸滩站2008～2010年的洪水过程。结果表明，该模型对洪峰的映射及洪水过程的模拟精度较高，预报效果理想。

It is difficult to establish flood forecasting system of complicated regional inflows river reach in hydrological forecasting domain. At the same time, the flood peak forecast precision is the key problems of flood forecasting process. Taking Cuntan hydrologic station for an example, BPPR network model is applied to establish flood forecasting model and the flood process from 2008 to 2010 are forecasted. The results show that the flood peak mapping and flood process simu-lation precisions are both higher, and the forecasting effect is satisfactory.
