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.
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.
