New High Head Leaf Gate Form with Smooth Upstream Face

This paper presents new smooth upstream face high head gate form that heavily reduces hydrodynamic forces in conjunction to a total absence of uplift (negative downpull) forces. The research work at the Institute of Hydraulic Engineering investigated techniques to reduce the hydrodynamic load on high head gates. Task was achieved with the new smooth upstream high head leaf gate; improved safety for the hydro-machinery equipment and also for concerned parts of the whole project, while minimizing costs.
