The runoff coefficient and the erosion modulus are related to the rainfall.

其径流系数与侵蚀模数与次降雨量、降雨强度有一定的相关性；

The runoff coefficient of 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。

In the mountainous watershed of the Heihe River, the runoff coefficient is much larger than that of the whole arid area, but it is still less than the average value over the whole country.

黑河山区流域径流系数远比干旱内流区的平均值大，但要小于全国的平均径流系数。

youdao

From every rain simulations the runoff coefficient was estimated with a average of 0, 19 (min 0, 01 and max 0, 46).
