| Abstract: | In this paper,two kinds of weirs,airfoir weir and hump weir,are studied by two dimensional mathematic model.Discharge coefficient curves and dynamic pressure distributions on the crest,especially the results of hydraulic characteristics of the airfoil weir,are obtained.The results show that the airfoil weir has a larger discharge capacity and there is no dangerous negative pressure along the weir profile. |

| Keywords: | control weir airfoil weir hump weir discharge capacity pressure distribution |
