Current knowledge of the physical effects of underwater explosions on the environment is summarized, with particular attention to the heating of water, the mixing of explosion products with water, and cratering. Theory and data indicate that thermal effects on the environment are negligible because rapid turbulent mixing reduces any temperature excess to a negligible amount within minutes. Virtually no data are available on the mixing of explosion products with water and air. However, information on the bubble and surface phenomena of underwater explosions has been utilized to provide qualitative guidance concerning the distributions immediately after a test. Existing theories of turbulent diffusion can be applied to calculate the subsequent history of the products. Knowledge of the physical effects of bottom explosions on the environment is limited to crater measurements in shallow water and some data on the behavior of explosion bubbles in deep water. Suggested programs to fill gaps in current knowledge are outlined. (Author).

Underground facilities are used extensively by many nations to conceal and protect strategic military functions and weapons' stockpiles. Because of their depth and hardened status, however, many of these strategic hard and deeply buried targets could only be put at risk by conventional or nuclear earth penetrating weapons (EPW). Recently, an engineering feasibility study, the robust nuclear earth penetrator program, was started by DOE and DOD to determine if a more effective EPW could be designed using major components of existing nuclear weapons. This activity has created some controversy about, among other things, the level of collateral damage that would ensue if such a weapon were used. To help clarify this issue, the Congress, in P.L. 107-314, directed the Secretary of Defense to request from the NRC a study of the anticipated health and environmental effects of nuclear earth-penetrators and other weapons and the effect of both conventional and nuclear weapons against the storage of biological and chemical weapons. This report provides the results of those analyses. Based on detailed numerical calculations, the report presents a series of findings comparing the effectiveness and expected collateral damage of nuclear EPW and surface nuclear weapons under a variety of conditions.

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.

Explosion Blast Response of Composites contains key information on the effects of explosions, shock waves, and detonation products (e.g. fragments, shrapnel) on the deformation and damage to composites. The book considers the blast response of laminates and sandwich composites, along with blast mitigation of composites (including coating systems and energy absorbing materials). Broken down under the following key themes: Introduction to explosive blast response of composites, Air explosion blast response of composites, Underwater explosion blast response of composites, and High strain rate and dynamic properties of composites, the book deals with an important and contemporary topic due to the extensive use of composites in applications where explosive blasts are an ever-present threat, such as military aircraft, armoured vehicles, naval ships and submarines, body armour, and other defense applications. In addition, the growing use of IEDs and other types of bombs used by terrorists to attack civilian and military targets highlights the need for this book. Many terrorist attacks occur in subways, trains, buses, aircraft, buildings, and other civil infrastructure made of composite materials. Designers, engineers and terrorist experts need the essential information to protect civilians, military personnel, and assets from explosive blasts. - Focuses on key aspects, including both modeling, analysis, and experimental work - Written by leading international experts from academia, defense agencies, and other organizations - Timely book due to the extensive use of composites in areas where explosive blasts are an ever-present threat in military applications

Plans for the Long Term Upper Ocean Study evolved over several years. As the plans became more definite a two year period was devoted to engineering tests at the LOTUS site (34°N, 70°W). Many aspects of the proposed plans were implemented during this period in order to evaluate the performance of the equipment and instrumentation. This report presents a summary of the planning and testing periods up to but not including the first science deployments in May 1982. Historical data collected at the LOTUS site prior to the engineering tests and the data collected as part of the engineering tests are presented.
