This book was released on 1969 with total page 82 pages. Available in PDF, EPUB and Kindle. Book excerpt: Laboratory data are presented for the runup on plane-faced seawalls of the leading waves from impulsive disturbances simulating underwater explosions. The tests covered walls with faces vertical and sloping 4:1 and 2:1 from horizontal, with foreshore slopes of 1:14 and 1:20. The tests covered two general classes of wave trains--specifically, trains with a leading trough (as produced by explosions in relatively deep water) and trains with a leading crest (as produced by explosions in relatively shallow water). The more important data pertain to the latter class, since significantly large explosions not far from shore are of the shallow-water type. A noteworthy aspect of the tests was the limited dispersion of the wave trains, resulting from the relatively short propagation distance and the large radius of the area covered by the disturbance, relative to the depth.

Book excerpt: Laboratory data are presented for the runup on a uniform slope of the leading waves of an axially symmetric, dispersive train of surface gravity waves. The waves emanated from an impulsive disturbance, simulating an underwater explosion. A significant aspect of the test conditions was the limited dispersion of the wave train, resulting from the relatively short propagation distance and the relatively large area covered by the wave-generating disturbance. Two general classes of wave trains were studied, distinguished by an initial rise of the water surface (a crest at the front of the wave train) in one case and an initial fall (trough) in the other. In both cases, the first wave in the wave train produced the greatest runup. The dominance of the first wave was more marked in the larger disturbances (higher waves). The more important leading-crest case simulated an explosion of the shallow-water type. This type is expected from explosions of large but not unrealistic magnitude in relatively shallow coastal waters. On a 1:14 slope, the leading crest did not break and the ratio of runup to wave height was constant (3.3) for ratios of wave height to water depth at the toe of the slope (H/d sub o) varying from 0.003 to 0.073. On a 1:20 slope, the leading crest broke with H/d sub o greater than 0.035; the runup of nonbreaking leading crests was 5% to 25% less than on the 1:14 slope, and breaking decreased the runup still further.

Available in PDF, EPUB and Kindle. Book excerpt: 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.
