Abstract

This paper describes a mathematical model of the large but short-lived forces exerted on submerged solid bodies by a wave impacting on a plane impermeable surface nearby. We consider the forces on a hemispherical boulder situated close to a wave impact on (i) a vertical wall and (ii) a steep slope. We show that for certain positions of the body and for a sufficiently strong wave impact the impulsive force on the body can be much greater than either the flow drag or the weight of the boulder. For a body which is free to move under the wave impulse we compute the body's initial velocity.
