Littoral transport rates and inlet bypassing quantities were estimated for a 19-mile 30.6 km segment of the North Carolina coast extending from Wrightsville Beach southward to Kure Beach, by adopting a sediment budget approach. The steps involved in the sediment budget analysis were a an estimate of volumetric changes along the shorelines and in the inlets, b wave refraction analysis to determine the distribution of longshore wave energy flux along the shoreline and, c a correlation of the volume changes with the computed longshore energy flux distribution. The base period used for this analysis was from 1966 to 1974. After the material transport rates were determined for this base period, an evaluation was made of the changes in shore processes resulting from man-induced alterations in the shoreline configuration. The major manmade alterations along this segment of the coast include the artificial opening of Carolina Beach Inlet in 1952 and the construction of the north jetty at Masonboro Inlet in 1966.
