| Nowadays, many researches focus on the distributed hydrologic process, for it is regarded as more physically and much closer to reality. Based on the digital elevation model, the flow direction and contributing area can be generated for the Lingkou Basin in the upper area of Luo River located in the Yellow River. The basin is divided into two blocks, BTOPMC Model has been performed on each block based on grids. The hydrometeorological data in special file format are taken as the input, the flow routing is done by Muskingham-Cunge method based on grids. The grid-by-grid spatial variability in soil and land cover properties is considered in calibrating parameters. The results show that the spatial properties can be described distinctly, which lays foundation for the further researches on distributed hydrologic process. |
