摘要
南四湖流域是一个复杂的大流域，是东线南水北调的重要调节湖泊之一，也是干旱和洪水频繁流域．本文首先采 用分布式的新安江模型，对有实测流量资料的支流流域进行了模型参数率定，洪量预报达到了一定的精度，建立了南四湖 流域的洪水预报模型．采用一维、二维水力学模型并与水文学模型耦合进行上级湖的流量演进以及二级坝水利枢纽的 调度．
Lake Nansihu is a complicated watershed. It is one of important regulation lakes for east route of Water Diversion Project from South to North. It is also the watershed of frequently occurrence of flooding and draught. At first, the distributed Xinanjiang model is calibrated for tributaries with the observed discharge data and the whole flood forecasting model is set up. The one and two dimension hydraulic models are coupled with hydrological model and used for the flood routing and flood regulation for upper lake of Lake Nansihu.
