The designed flood peak flow in storm sewer is usually calculated by adopting a constant average runoff coefficient at present in China, simple as it is, it's not reasonable enough.

目前，我国采用单一地表的平均径流系数计算雨水管渠的设计洪峰流量，这虽然使计算简化，但不尽合理。

The invasion coefficient is put forward because the flash flood must invade into the residence block and buildings. In order to compute the invasion water, the side weir idea is used.

为了考虑侵入社区和楼房内的洪水水量，提出了侵入水量的概念，并借用侧堰流的思想给出了这部分水量的估算方法。
