WATER WAVES FROM 10,000-LB HIGH-EXPLOSIVE CHARGES. OPERATION HYDRA II- A
1963
Van, William G. | Montgomeryb, W. S.
Water waves were recorded at three stations for eight out of thirteen 10,000 lb high-explosive charges detonated during the HYDRA IIA test pro gram at San Clemente Island in the summer of 1961. The charge submergence varied from 6.6 to 140 ft in water 300 ft deep. Since the waves traveled over sloping topography, the theory of geometric optics was employed to reconstruct equivalent wave trains as they would have devel oped over a flat horizontal bottom in water 300 ft deep. The linear theory of Kranzer and Keller for the wave system initiated by a parabolic crater in the water was forced to fit the reconstructed HYDRA wave trains by suitably adjusting the input crater dimensions until the phase and amplitude of the predicted wave train was in good agreement with the reconstructed trains.
