| 摘 要： | 选择位于黄河支流洛河中游的长水—宜阳区间流域作为研究对象,基于数字高程模型,计算栅格水流方向、集水面积和栅格演算次序,为产汇流计算打下基础。把1个栅格单元作为1个小子流域,基于栅格采用新安江模型进行产流计算,采用Muskingum-Cunge算法进行河道洪水演算。结果表明,基于DEM的分布式水文模型在洪峰误差控制和过程拟合等方面表现较好,洪水模拟具有较高的精度。

| Abstract: | Based on the digital elevation data,the grid flow vector,accumulation area and calculation order were generated for the middle basin between Changshui and Yiyang on the middle Luo River,which laid foundation for calculation of runoff and confluence.The author regarded a grid cell as a small catchment,based on which runoff calculation was performed by using Xin'anjiang model,and then channel routing was performed by using the Muskingum-Cunge method,thus,a distributed hydrological model with high precision was derived.The results show that it performed well in controlling flood peak error etc. |
