摘要
WATFLOOD模型是基于物理基础的分布式流域水文模型。为了研究其在国内湿润流域的合理性和适用性,结合数字高程、土地利用等资料,将WATFLOOD模型应用于呈村流域,对该流域1990—1999年间的18场洪水进行径流模拟。另将新安江模型也应用于该流域对这18场洪水进行径流模拟,并对两种模型的原理结构和洪水特征值进行比较分析。两种模型模拟精度差异不大,结果比较满意。表明WATFLOOD模型在湿润流域具有一定的适用性。
WATFLOOD is a physically based distributed hydrologic model In order to study the applicability and rationality of WATFLOOD model in humid basin in China, the model is applied to simulate eighteen floods in Chengcun Watershed from 1990 to 1999 by using the data of DEM and land use type. The Xinanjiang model is also applied to the flood simulation in Chengcun watershed, and two kinds of model structure and flood characteristic values are compared. The simulation results of two models are satisfactory and only have little difference. It shows that WATFLOOD model can be applied in humid basin as well.
