Coastal Sediment Budget Analysis Techniques

by James T. Jarrett, U.S. Army Corps of Engineers, Wilmington, United States,



Document Type: Proceeding Paper

Part of: Coastal Sediments

Abstract:

Sediment budget analysis techniques developed by the U.S. Army Corps of Engineers Wilmington District are described. The basic procedure combines information on shoreline and tidal inlet volume changes with computed estimates of the longshore wave energy flux to arrive at longshore sediment transport rates that balance the sediment volume transported into and out of littoral cells. The procedure has been used for most segments of the North Carolina coast which has shoreline orientations ranging from north-south to eastwest. The longshore transport rates computed by this procedure are realistic and have been used in the planning and design of various types of coastal projects ranging from storm damage reduction to navigation improvements through tidal inlets.
