Wave heights are increasing, with some latitudinal variation, everywhere along the Southeastern U.S. Atlantic coast. Shoreline shape and shelf bathymetry appear to act as first order controls for the locations of erosion and accretion. In addition to changes in wave height, changes in period and direction play a strong role in the distribution of hotspots of erosion and accretion. For a constant deep water H & D, increases in T (more well organized distant source) tend to exaggerate the coastal response, either erosional or accretional
