摘要
HEC-HMS系统集大量降雨径流计算模型于一体,包括净雨计算模型、直接径流过程计算模型、基流计算模型和河道洪水演算模型。将其用于篓子沟流域进行了实例应用,根据自然分水线将流域划分成43个子流域,所用产汇流计算模型为:初损后损法模型、单位线、指数消退模型和Muskingum河道演算模型。根据对12场降雨径流过程的模拟可以看出,结果是比较理想的。
HEC-HMS includes a lot of models which can be used to compute the rainfall runoff, including models of the runoff volume, the direct runoff, the baseflow, and the channel flow. This paper is an attempt to describe the construction of HEC-HMS. Use is made of HEC-HMS in the Louzigou River basin, which is divided into forty-three sub-basins by natural division. Methods used are initial and constant-rate loss models, UH hydrograph models, exponential recession models and Muskingum models. Simulations of twelve runoff events are conducted, and good results are obtained. HEC-
