ANALYTICAL STUDY OF CERTAIN ASPECTS OF UNDERWATER SHOCKWAVE PROPAGATION: SLOPING BOTTOM, ICECAP, SEDIMENTARY BOTTOM
Abstract
Various problems concerning the effects of the boundaries of the ocean on the propagation of pressure waves in the ocean are considered. The propagation of a transient pressure wave in a wedge shaped region of fluid is treated. This is the model chosen to describe the situation in which an underwater explosion takes place in a coastal region which is characterized by a strongly sloping bottom. In an attempt to study the effects of the polar ice cap on the propagation of a pressure wave, the reflection of a plane wave onto a rough boundary separating a fluid half space and a thick fluid layer of differing sound speed and density is considered. These results are currently being used to construct the response to a transient pressure pulse and to generate numerical results for conditions representative of underwater explosions. The final section presents numerical values of the reflection coefficient as a function of grazing angle for the case of a plane wave incident on a porous elastic bottom.
