CAPE HATTERAS BEACH NOURISHMENT

John S. Fisher, Wilson N. Felder

Abstract


The 1973 beach nourishment at Cape Hatteras placed approximately 465,000 m on the subaerial beach. Eighteen months later, about 51 percent of this material remained on the beach. During this period there were relatively few major storms, and this mild wave climate is largely responsible for this high retention. At the end of this monitoring period the beach was stable and fully capable of providing shoreline protection and recreation. A correlation is presented relating storm erosion with the complete storm wave climate, including a post-storm period. A new parameter is defined which includes a measure of wave steepness and longshore current velocity.
