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 said weir has great overturn-resisting and slip-resisting safety coefficient in blood or swift rivers, and it is beneficial to water-channeling irrigation.
The invasion coefficient is put forward because the flash flood must invade into the residence block and buildings. In order to compute the invasion water, the side weir idea is used.
