| 摘 要： | 以分布式水文物理模型BTOPMC为平台,选取四川省东南地区湔江、石亭江、明江流域为研究区域,探讨降雨时间尺度对该模型参数的影响,以提高模型洪水模拟结果的精度,并为建立流域物理特性与模型参数之间的定量关系提供参考。结果表明,不同时间尺度下三个流域不同洪水过程模拟结果均较好,1h时间尺度下的模拟结果纳希效率明显高于2h、3h时间尺度。

| Abstract: | BTOPMC(Block-wise use of TOPMODEL with Muskingum-Cunge method),a physically-based distributed hydrological model,is applied in Jianjiang,Shitingjiang and Mingjiang River basin in southeast of Sichuan Province to study the time scale effect of precipitation on model parameters.Thus,it provides a reference for establishing quantitative relationships between model parameters and physical basin features.It results show that the simulation results in three basins are preferable to describe the flood process at the different time scales;Nash efficiency coefficient E in 1h time scale is obvious higher than that of 2h and 3h time scale. |
