The text introduces the calculation of overfalling quantity should be based on broadcrestedweir or short canal when renovating overtopping flooding.
提出整治工程漫顶溢流时溢流量按宽顶堰或短渠计算；
2
The method was adapt broadcrestedweir theory derivation to calculation flood rate of discharge and conjecture design rate of discharge through field investigate information of bridge.
该计算方法是通过实地调查桥前水深等资料，采用严密的宽顶堰理论推导，求得洪水流量，进而推求设计流量。

The results of flood carrying capacity curve and discharge coefficient for camel hump weir and broadcrestedweir have been obtained by sectional hydraulic model test of Miaozitou sluice.
