概念性汇沙模型初探

A Tentative Study of Conceptual Sedimentation Routing Model

本文从概念性角度探讨泥沙基本规律.把水文学中的线性水库、马斯京枢法的水流汇集概念应用到流域坡面和河道的泥沙汇集中,考虑泥沙汇集与水流汇集的共性和泥沙冲淤的个性,提出简单的概念性坡面汇沙、河道汇沙模式;结合时段地面经流与时段产沙量的关系,构成一个产流和产沙、汇沙藕合模型;并应用于黄河流域产沙、汇沙规律的分析和断面泥沙过程的模拟,获得了较合理的结果.

This paper approaches sediment concentration from the conceptual angle.The concepts of linear reservoir and Muskingum method,which are used in hydrology,are intooduced into the sedimentation model to route the sedlimentation from the hill-slope area to the river channel and from the upper river channel to the outlet section.The conceptual model is applied to simulate the sedimentation graph of the Yellow river catchment and the results are satisfactory.
