Clark单位线法的分布式改进
Improvement of Clark Unit Hydrograph to Distributed Unit Hydrograph Model
摘要
Abstract
In view of the linear characteristic of Clark unit hydrograph,a distributed unit hydrograph representation was proposed in which the unit hydrograph for each derived isochrones of areas with Nash's linear reservoir model can be established and then are overlaid in consideration of lag-routing time. Calculus parameter in the distributed unit hydrograph model can be computed by two methods: integral or gradually arithmetic average. In association with the proposed distributed unit hydrograph model,the unit hydrograph in Yandu river watershed was calculated and the result is consistent with that computed using Clark method by others. The result suggests that the improve-ment on Clark unit hydrograph by distributed representation in this article is reasonable,hence offering a foundation for further improvement in the application to hydrological response unit in the future.关键词
