Abstract

The hydrodynamic pressures for a vertical flood gate situated in a discharge sluice are investigated. Exact analytical solutions are presented for the hydrodynamic pressures acting on the gate. This solution is first employed to investigate the hydrodynamic pressures for a horizontally vibrating rigid gate. For this case, regimes of frequencies and water depths are identified for which fluid compressibility and surface waves play a significant role in the hydrodynamic response. Subsequently, the hydrodynamic pressure is analysed for the case of a flexible gate of various boundary conditions. It is concluded that the derived regimes are applicable to flexibles gates as well. Values for the added mass coefficient are presented for various types of gate supports.
