Violent Motion as Near Breaking Waves Meet a Vertical Wall
Very steep unsteady water waves are modelled by an accurate numerical computer program. Recent work is discussed with particular emphasis on waves that are nearly breaking as they approach a vertical wall. Extremely violent water motion is calculated in full detail, with water accelerations exceeding 1000 g, and transient pressures exceeding 30 times the hydrostatic pressure.
