Rainwater may infiltrate more easily with a higher initial soil water content and a deeper surface pond.
初始含水量越高和地表积水越深越利于雨水的入渗。
There was a decreasing trend in each pollutant concentration with rainfall duration and finally tends to flat. So we collect the rainwater after abandoning part of the initial flow of rainwater.
并且各污染物浓度均随降雨历时呈减少趋势，后趋于平缓，可采用弃流部分初期雨水后进行收集。
