Abstract

Two detached breakwater projects in Louisiana were investigated. At Grand Isle, Louisiana, breakwaters do not seem to have caused any sediment deposition. Airphoto analysis indicated that the breakwater field has caused changes in morphology, though. At Holly Beach, Louisiana, breakwaters have caused sediment deposition, specifically low tide tombolos. Analysis of survey data and tracer data indicated that the beach/breakwater system is in a state of dynamic equilibrium at high tide, and static equilibrium at low tide. In addition, wave heights measurements were made in the vicinity of one breakwater segment and compared to incident wave height. Examination of the data indicated that the incident wave characteristics had little correlation with wave heights in the immediate area of and landward of the structure.
