摘要

通过室内模拟降雨试验分析了不同坡形坡面径流流速的时空分异特征

研究结果表明:同雨强、同坡度条件下

直线形坡的坡面流速最大

凸形坡的其次

凹形坡的最小

并且在同坡形条件下

坡面流速随雨强、坡度的增加而增加。另外

不同坡形坡面径流流速在空间上也存在一定的差异

坡面径流流速基本上沿着坡面向下逐渐增大

并且坡面上各段流速随坡度、雨强的增大而逐渐增大。

Abstract

This literary grace uses the on trial method that the indoor artificial simulated rainfall

analysis the velocity spatial distribution of the thin layer flow with the time on different form slopes.Main research result is as follows: The velocity of flow

on the condition of the same rainfall intensity and slope gradient

the linear form slope is the biggest

the convex form slope the next

and the concave form slope the least.Under the condition of the same slope form

the slope surface current velocity is increases with the rain intensity and the slope gradient.And then

slope surface current velocity is different in different form slopes.But the general rule is that the slope surface current velocity is increases with the increase of the rainfall intensity and the slope gradient.
