河道沿岸土体崩塌阻塞水流的影响研究

Study on the Influence of the Collapse and Blocking of Water on the Soil along the River Channel

本文利用CCHE-2D数值模型软件仿真探讨A溪遭到崩塌土石阻塞后,在不同重现期的来水及来砂量下,对河道左岸生态环境的影响。经模型软件检定及验证后,进行崩塌土石阻塞河道程度的情境模拟。

This paper uses CCHE-2D numerical simulation software to simulate the impact of the collapsed earth and stone in Lasai Creek on the left bank of the river bank in different return periods and the amount of incoming sand. After the verification and verification by the model software, a simulation of the situation of the degree of river blockage by collapsed earth and rock was performed.
