城镇雨排水与农田排涝流量计算方法对比分析

The comparative analysis of the computing methods between urban rain drainage flow and agricultural drainage flow

从暴雨统计、径流系数、汇流3个环节入手,对城镇雨排水及农田排涝流量的计算方法进行对比分析,得出径流系数和汇流环节是导致流量成果相差较大主要因素的结论。

This article starts from three aspects consisting of storm statistics, runoff coefficients and confluence, contrastively analyzes the computing methods of both urban rain drainage and agricultural drainage flow, and concludes that runoff coefficients and confluence are the primary factors leading relative large difference among flow outcomes.
