Regional Sediment Management (Winyah Bay/Charleston Harbor)

The Burroughs & Chapin Center for Marine and Wetland Studies (BCCMWS) at Coastal Carolina University (CCU) conducted hydrographic surveys for the major tidal inlet features of Charleston Harbor Inlet in Charleston County and Georgetown Harbor Inlet in Georgetown County. The objective of the study was to collect bathymetric data at a sufficient density to develop accurate digital elevation models. The resulting models will be used to delineate major inlet features, evaluate sediment volumetric change, and serve as input for numerical model grids. In addition, beach profiles and surficial sediment sampling and analysis were conducted to characterize the active beach systems adjacent to the Winyah Bay entrance. The project was conducted in three phases. Phases 1 and 2 were at Georgetown Harbor Inlet and Phase 3 was at Charleston Harbor Inlet.
