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.

Flow field of upstream and downstream of Xiao gushanwater power station hinge discharge sluice were practical calculated examples.

Transform the former no -sluice wide-top weir into sluice-controlled hump weir can make the dispatching more easy and increase the flood discharge capability.
