PERFORMANCE CHARACTERISTICS OF SUBMERGED BREAKWATERS

Coastal Engineering Proceedings, 1978
Submerged breakwater is a barrier with its crest at or slightly below the still water level. In situations where complete protection from waves is not required, submerged breakwaters offer a potentially economic solution. Submerged breakwaters have been effectively used to protect harbour entrances, to reduce siltation in entrance channels, against ...
