The increase of rainwater runoff, runoffcoefficient increases, the formation of the ground.
汇流的雨水增加，径流系数增大，形成了地面的雨水径流。

The runoffcoefficientof every underlying surface was forecasted in different rainfall conditions by ANN models and compared with conventional method as well.
用该方法对不同降雨条件下每种下垫面的径流系数进行了预测，并与传统方法进行了比较。
3
Landscape features of the basin mean little difference between the standard deviation of the value of landscape features smaller basins, inter-month changes in runoffcoefficient is more gentle.
