Coastal Change Along the Shore of Northeastern South Carolina: The South Carolina Coastal Erosion Study

Figure 3.9.  Perspective view of the Grand Strand region looking towards the northwest.  Arrows indicate changing locations of the Pee Dee River over time (generalized from Baldwin and others, 2006).  Progressive, southwestward deposition along ancient shorelines gradually deflected the river toward the southwest.  Older (more landward) shorelines initially trended east-west, but rotated to northeast-southwest as they were deposited progressively closer to the modern coastline.  Shaded relief of the regional surface defining the base of Quaternary sediments (also displayed in Figure 3.5a) shows that the river carved at least seven distinct courses across the region prior to its current configuration, which flows through Winyah Bay.  The background-shaded relief imagery was constructed by using the NOAA-NGDC coastal-relief model. >, higher than; <, deeper than.  [Click here for high-resolution image.]
