RUN-UP BY IMPULSIVELY GENERATED WATER WAVES,
Abstract
Theoretical and experimental studies were conducted to determine the run-up on a plane beach produced by systems of impulsive generation. The facility used for the studies consists of a wave basin which simulates the run-up of actual ocean waves on beaches. Wave trains were generated by bobbing the plunger up and down pneumatically in a single stroke or in arbitrary sequences chosen to produce wave trains simulating these produced by underwater or surface explosions. The para boloidal shape of the plunger was chosen because it resembles the crater produced by an underwater explosion. The wave trains were recorded at several distances from the center of plunger, and the corresponding run-up on test beach units of 1:15 slope was recorded. Theoretical results were derived and compared with the observed results. The extent of agreement between theory and experiment is discussed, and preliminary conclusions are that an adequate theory exists to predict wave generation due to underwater highexplosive blasts.
