北江洪水预报模型

Flood Forecasting Model of North River Watershed

将北江流域按区域下垫面特征进行分区，建立起各单元区产汇流模型，并与北江干流非恒定流水力学演算模型耦合，形成适合北江流域洪水特点的实时洪水预报模型．用北江“９４６”洪水验证的结果表明，模型预报精度较高．最后，还指出了模型存在的问题和进一步研究的方向．

Based on the characteristics of the land of North River watershed,the watershed is divided into several sub areas.Correspondly,the rainfall runoff models of each sub area and the coupled unsteady flow numerical computation model form the flood forecasting model of North River watershed.The application results show that the models are quite satisfactory. Finally,some problems which needed to be addressed on study further were pointed out.
