Abstract : Theoretical predictions of the water waves generated by explosions in shallow water--wave propagation at constant depth and wave amplification in shoaling water--are presented based on the pulsation of a gas-filled right circular cylinder. At constant depth, the waves are asymmetric with respect to the still water level and have a primary orbital oscillatory motion which is dispersive in nature and a secondary rectilinearly oscillatory seiche-like motion with a much longer period. In shoaling water, specific waves in the incident wave train are found to have specific amplification factors. (Author)
