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.
In a digital weir, open loop digital control is applied, and the method is simple and reliable. And it can give accurate flow according to the given process curve.
