Vertical lift tunnel type gates are subjected to hydrostatic and hydrodynamics forces created as a result of operation conditions over a wide range of partial openings, discharge and heads. Among these forces is the downward hydrodynamic force resulting from the effects of flow issuing over the top gate surface. The evaluation of this force needs the determination of top pressure coefficients which based mainly upon the measurements of the jet flow velocity across the vena-contracta , pressure head variation on the top gate surface and pressure head of flow just downstream the gate shaft.In the present research, a random hydraulic model was created to specify the effect of twelve gate lip shapes on the behavior of flow and consequently on the top pressure coefficients. The results reveal that no significant of gate geometry on the top pressure coefficient.
