摘　　要：SIMHYD模型结构简单,参数较少,被广泛应用于流域月尺度和日尺度的径流模拟,由于模型结构中缺少流域汇流部分,尚无法满足小时尺度的洪水预报与模拟的需要。为此本文开展SIMHYD模型研究,针对模型结构存在不足,在SIMHYD模型基础上,设计对比4种不同汇流方案:①不考虑汇流(原始SIMHYD模型);②仅增加河道汇流;③仅增加坡面汇流;④同时增加河道汇流和坡面汇流。并在淮河王家坝区间流域开展小时尺度的洪水模拟应用研究。研究结果表明,相较于原始SIMHYD模型,增加汇流之后的SIMHYD模型模拟精度均有所提高,其中,同时增加河道汇流和坡面汇流的SIMHYD模型模拟精度提升最大。本研究通过改进SIMHYD模型的汇流部分,使该模型可以应用于小时尺度的洪水预报与模拟,且模拟精度较高。SIMHYD model has simple structure and few parameters,so it is widely used in monthly and daily scale watershed runoff simulation.Due to the lack of watershed confluence part in the model structure,SIMHYD model cannot meet the needs of hour-scale flood prediction and simulation.For this reason,SIMHYD model was studied in this paper.In view of the shortcomings of the model structure,four different confluence scenarios were designed and compared on the basis of SIMHYD model:(1)No confluence was considered(original SIMHYD model);(2)Only increase channel confluence;(3)Only increase the overland confluence;(4)At the same time increase the channel and overland confluence.And carry out the hour-scale flood simulation application research in Wangjiaba sub basin of Huaihe River.The research results show that compared with the original SIMHYD model,the simulation accuracy of SIMHYD model with addition of confluence is improved,and the simulation accuracy of SIMHYD model with addition of channel confluence and overland confluence is improved the most.In this study,the SIMHYD model can be applied to hour-scale flood prediction and simulation by improving the confluence part of the model,and the simulation effect is better.
