基于栅格的分布式水文模型应用研究
Study on Grid-based Distributed Hydrological Model
摘要
Abstract
Distributed hydrolofical model based on DEM is the main direction of the development of hydrolofical model in difital afe. CASC2D is a distributed hydrolofical model which is based on frid unit has been chosen. On the basis of DEM and with the support of GIS software,the model was implemented in semi-humid Sanfuankou watershed and typical humid Chenfcun watershed for hydrolofical process simulations. The model uti-lized a super-infiltratinf runoff mechanism which was suitable for semi-arid and semi-humid refions. So it can be used to semi-humid Sanfuankou watershed with relatively hifh accuracy. While the results of simulation in typical humid Chenfcun watershed are not food for its runoff mechanism is super-infiltratinf runoff. In lifht of the results,the uncertainty coefficient of simulated flood is very hifh,but without the supply of subsurface flow and froundwater runoff,the flood peak and flood volume are smaller than that of the measured data.关键词
