|Abstract:||Laboratory tests were conducted to determine transient wave train characteristics (wave height and time series) generated as a result of steel discs falling into shallow water. Steel plates ranging from 2.8 to 6.0 feet in diameter were dropped from various heights into test basins with water depths ranging from 0.2 to 1. 2 feet. Capacitance-type wave gages were used to obtain wave height data at various distances from the edge of the steel discs. Water current magnitudes also were obtained at selected locations, and photographic coverage was llsed to document vessel. movements of small-scaled submarines. Instrumentation was installed on the steel discs to measure acceleration, and an automated data acquisition and control system was used to obtain and analyze wave data. Plots are included that present results of these tests.|
