The experiments were made using a rigid rectangular model tank which was forced to roll with small amplitude. The dimensions of the tank were 100cm×92cm×40cm. The oscillation periods range from the resonance period (T_n) of water in the tank to three times of T_n. The pressure and the wave amplitude in partly-flooded tank were measured. Through a series of experiments, it is found that the impulsive pressures are generated by the water impact (1) of the wave front on the side wall, (2) of the water mass which climbs the side wall and then bounces onto the opposite side wall, and (3) of the wave crests hitting the tank top, when the water levels were 30%, 60% and 90% of the tank depth, respectively. Maximum impulsive pressures on the side wall were observed at the neighbourhood of the still water level.
