WAVE PRESSURES ON SLIT-TYPE BREAKWATERS

For severe storm waves with periods of 7.0 sec to 14.0 sec and heights of 6.3 m to 9.0 m, it was proved that the resultants of the maximum simultaneous pressures exerted by breaking waves on the slit-type breakwaters with the optimum relative chamber width of 1/L = 0.05 to 0.07 were in most cases less than 70 per cent of those exerted on the conventional composite-type breakwaters.
