汇流宽度随集水面积变化的分布式水文模型
A Distributed Hydrologic Model of Varying Flow Path Widths with Contributing Areas
摘要
Abstract
Grid width is generally treated as the width of flow path for flow convergence in many traditional distributed hydrologic models.The flow velocity obtained from these models differs substantially from the reality,which may undermine immensely the accuracy of the results in hydrologic modeling,soil erosion simulation and other related studies.A distributed hydrologic model was developed based on Horton infiltration curve and simplified Saint Venant equation in this study.A curve called as flow path width curve was developed to describe the varying of flow path width with upstream contributing area as flow gathering.Some observed data of Dongwan watershed was applied to test the model,and the results proved its superiority in distributed outputs.关键词
