This study presents a semi-empirical evaluation procedure for determining the hydrodynamic push-and-draw pressure induced by an inclined circular-arc skinplate undergoing streamwise rotational vibration while positioned above a curved dam crest. First, model experiments were conducted to measure the hydrodynamic pressure acting on the rotationally vibrating inclined circular-arc skinplate above the curved dam crest. Then, the resulting experimental values were carefully compared with the calculated hydrodynamic pressure for a vertical flat weir plate above a flat channel floor. It is then shown that the hydrodynamlc pressure on a circular-arc skiplate above a curved dam crest can be evaluated by empiricaily adjusting the pressure correction factor 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.
