Sediment Redistribution

     The forces responsible for erosion operate beyond the shoreline, within the broader coastal zone. In addition to actively eroding upland sediments, those forces, magnified by the storm, were directly responsible for extensive reconfiguration of the Bay margin, redistributing sediments temporarily stored on beaches and in shallow nearshore waters.

Bulldozers removed several feet of sand transported from the beach to a nearby road. Piney Pt., Potomac R., St. Mary’s Co. [10]
