Hurricane-Generated Waves and Coastal Boulder Rampart Formation.
Abstract
Coral boulder ramparts along the south coast of Grand Cayman Island have no source area near the shoreline. Coral communities acting as a source of rampart rubble are found 0.3 km from shore and at a depth of 10-12 m. Theoretical calculations of wave-induced forces from wave refraction analyses of hurricane-generated waves indicate that the probable hurricane dynamic force spectrum is sufficient to break and transport coral rubble from depths of up to 12 m. In situ breaking force tests accomplished in Puerto Rico on Acropora palmata coral colonies support the theoretical calculations.
