Abstract:

Studied were made in a laboratory test basin to determine the feasibility of modeling run-up effects of explosively generated water waves on beach and waterfront structures. Results were compared with i analytically derived predictions, and ii wave measurements but not run-up made in the ocean with high-energy HE explosives as the generating source. The test basin is 92 feet by 94 feet in size with 15, 113.6 and 15 sand beaches on three sides and on the fourth a 14-foot-diameter semi-paraboloidal plunger which by sudden plunge or retraction generates dispersive waves with dominant period of 2 seconds, height of 0.2 feet, and length of 20 feet in water 2-12 feet deep. It was found that wave motions are i predicted well by Greens Law, as modified for dispersive waves and ii related to waves generated in the ocean by HE by the Froude scaling law.
