This study presents a semi-empirical evaluation procedure for determining the hydrodynamic flow-rate-variation pressure induced by an inclined circular-arc skinplate undergoing rotational vibration around the trunnion pin while positioned above a curved dam crest. First, the hydrodynamic flow-rate-variation pressures acting on the inclined circular-arc skinplate above the curved dam crest due to the rotational vibration around the trunnion pin were measured in detail. Then, the resulting experimental values were carefully compared with the calculated hydrodynamic pressure for a vertical flat weir plate above a flat channel floor. Then, the measured hydrodynamic flow-rate-variation pressure on a circular-arc skinplate above a curved dam crest can be evaluated by empirically adjusting the flow-rate variation coefficient and the gate submergence to reservoir depth ratio in the previously developed calculation procedure for the hydrodynamic pressure induced by a vertical flat weir plate above a flat channel floor.
