基于地貌学和水文学的流域汇流模型

流域汇流是一个三维水文学问题，主要依赖于流域的河网地貌和河槽动力特征。本文在地貌学和水文学研究基顾上建立了概念性的流域模型，模型参数可由地貌参数和河槽动力特征值推求，该模型是非线性模型，概念清楚，求解地较简便，且可用于缺乏水文资料地区的流域汇流计算。

A Watershed4 Flow Concentration Model Based on Geomorphology and Hydrology

Watershed flow concentration is a three dimension hydrological phenomenon, mainly concerning with thelandforms in river network and dynamic characteristics in river channels. Based on the geomorphology andhydrology, this paper gives out a concept model, in which parameters are compulated with the geomorphologicparameters and dynamic characteristic values of river channel. As a nonlinear model with clear concept, it is notonly simple for computation, but also can be used for the computation of watershed flow concentration inungaged basins.
