Abstract/Summary This paper investigates the impacts of coral reef morphology and surface roughness on the islands protected by them under difference Sea Level Rise (SLR) scenarios. To address this, a simplified coral reef profile was considered. A one dimensional SWAN wave model was setup and run for a large number of different cases of top reef width and depth, lagoon width and depth and surface roughness for a representative mean climate of the Great Barrier Reef (GBR) islands and different SLR scenarios. It is concluded that any change of surface roughness, and reef flat depth and width because of climate change leads to significant changes of water orbital motion and nearshore wave height which are important for ecological processes and longshore sediment transport.
