Abstract

The influence of nearshore hardbottom on longshore and cross-shore sand movement along a 21.2 km long southeast Florida coastline is evaluated. This study correlates a variation of longshore sediment transport rate within the region with the extent of nearshore hardbottom. The nearshore sand movement within this region was determined based on analysis of the hydrographic survey data over a 15-year period. The study area includes three major beach renourishment sites, which were renourished a combined total of seven (7) times with 5.5 million cubic meters of sand. The objectives of this study are to obtain a greater understanding of the causes of severe beach erosion and a more accurate estimate of nearshore sand movement in the region, thus providing a better design tool for future beach nourishment projects and inlet sand bypassing practices.
