Available in PDF, EPUB and Kindle. Book excerpt: The kinematics of surface gravity waves produced in water 2.5 feet deep in a basin 90 feet square by a sudden, localized disturbance was studied through measurements of height and period. The waves were generated by the quick withdrawal or immersion, or combinations of these actions, of a 14-foot-diameter half-paraboloid plunger located near the mid-point of one wall of the basin. Smaller plungers of diverse shapes were also used. Measurements were made both in the constant-depth portion of the basin and over a beach with a uniform slope of 1:13.6, which was directly opposite the plunger. At the shoreline about 80 feet from the plunger, waves produced by a sudden withdrawal, for example, were 3 inches high, with a maximum period of 3 seconds. The waves compare adequately with those predicted by the theory of Kranzer and Keller, although they were 40% smaller and 20% shorter. By extrapolation, it was found that waves were produced which adequately simulated those from the actual underwater detonation of a high-energy explosive (5 tons TNT) and a nuclear device (20 kt equivalent). It is concluded that with proper scaling the plunger can be used to simulate waves from such causes. (Author).

Available in PDF, EPUB and Kindle. Book excerpt: This is the first book on explosion-generated water waves. It presents the theoretical foundations and experimental results of the generation and propagation of impulsively generated waves resulting from underwater explosions. Many of the theories and concepts presented herein are applicable to other types of water waves, in particular, tsunamis and waves generated by the fall of a meteorite. Linear and nonlinear theories, as well as experimental calibrations, are presented for cases of deep and shallow water explosions. Propagation of transient waves on dissipative, nonuniform bathymetries together with laboratory simulations are analyzed and discussed.

Available in PDF, EPUB and Kindle. Book excerpt: In the course of developing the capability of predicting the characteristics of water waves generated by explosions detonated in shallow water beneath the ocean floor, the pertinent data from past experiments were analysed using dimensional analysis as a framework. Data were examined from one series of high explosive cratering experiments detonated beneath the floor in shallow water, and from two series of high explosive experiments and one nuclear explosive experiment detonated above the floor in shallow water. The data indicate that the maximum radius of the water column produced by the explosion is proportional to the cube root of the ratio of explosive yield to ambient pressure at the point of detonation. Further, the data show that the maximum radius of the column of water is proportional to the square root of the product of wave height and distance from the source. The conclusions of this scheme of analysis are being tested with hydrodynamic computer code calculations.

Book excerpt: The present treatise assembles the theoretical foundations and experimental results on the generation and propagation of water waves generated by underwater explosions. After a brief overview of the physical processes and a presentation of order of magnitude of explosion generated water waves (EGWW) as function of explosion parameters, linear theories and experimental calibration are presented. Nonlinear wave theories and their calibration are necessary in shallow water when the water crater caused by the explosion is not small compared to water depth. The importance of dissipation processes due to wave-sea floor interactions is emphasized, particularly when an EGWW travels on long continental shelf. Methodologies for the propagation of transient waves over 3D bathymetries are developed. The simulation of EGWW in the laboratory is reviewed. Finally, a numerical method based on Boundary Integral Method is applied to investigate the dynamic of bubble formation and wave generation near the explosion. (MM).

This book was released on 1981 with total page 45 pages. Available in PDF, EPUB and Kindle. Book excerpt: This report considers an array of simultaneous underwater nuclear explosions generating plane tidal waves on the continental shelf. Computer simulations are used to study this wave generation process. They are based on non-linear shallow water theory with an initial condition of a stationary raised cone of water. The sensitivity of the wave height to different yields, combination of different yields, spacing, alignment, timing, and bottom slope is determined. The reference values used for this study are a yield of five kilotons TNT, one kilometer spacing, water depth of 100 meters, and no bottom slope. In addition to the sensitivities, the amount of non-linear effect is illustrated by comparison of wave contour printer-plots generated by linear and non-linear shallow water theory. The computer results indicate the wave generation is relatively insensitive to realistic variations in the parameters. (Author).

This book was released on 1968 with total page 68 pages. Available in PDF, EPUB and Kindle. 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.

Book excerpt: Advances in Hydroscience, Volume 8, provides an overview of the state of knowledge in hydroscience. The book contains six chapters and opens with a study on seiches—a phenomenon that frequently occurs in large enclosed bodies of water and that can result in serious destruction of shore structures and bring sudden death to innocent swimmers. This phenomenon bears certain resemblances to the tsunamis and storm surges over the open sea. Subsequent chapters deal with the basic principles underlying the techniques in isotope hydrology; statistical models for ocean waves and wave forces; fluvial sediment transport; impulsive waves; and channel networks. This contribution will prove particularly useful to hydrologists, since most work in this field has been done by physicists or other non-hydrologists.
