IMPULSIVE PRESSURE DUE TO WAVE IMPACT ON AN INCLINED PLANE WALL

We obtain the expression of the pressure impulse distribution analytically on an inclined plane wall in an integral form by using Cooker and Peregrine's (22nd Int. Conf. on Coastal Eng., pp. 1473-1486) model. We can evaluate the integral analytically when the impacting wave has a special form - that is, the normal component of fluid velocity on a wall just before impact has a particular distribution. The relation between the maximum pressure impulse and the inclination angle of a wall is investigated. Although, of course, the relation depends on an incident wave, we find theoretically that the maximum pressure impulse on a wall becomes the largest in the case of a near-vertical wall.
