The results of flood carrying capacity curve and discharge coefficient for camel hump weir and broad crested weir have been obtained by sectional hydraulic model test of Miaozitou sluice.
The method was adapt broad crested weir 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。

Experiment and analysis of movable weir for flow measurement indicate that the modular limit of movable weir is relatively high. And the accuracy of theoretical discharge calculated is satisfied.
