A sediment budget analysis was performed for the vicinity of Masonboro Inlet and adjacent beaches, by the U.S. Army Engineer District, Wilmington, for understanding response of the inlet complex and associated beaches to dredging of Masonboro Inlet and to dredged material placement operations along the beaches of Masonboro Island south side of inlet and Wrightsville Beach north side of inlet. The analysis provides valuable information to assess the most effective beneficial use of dredged material from the Masonboro Inlet complex. The analysis of longshore sediment transport calculations showed a net transport towards Masonboro Inlet from both sides of the inlet. The calculated transport rate from Masonboro Island onto the offshore ebb shoal of the inlet complex was 78,530 cubic yards per year cyyr while the transport rate from Wrightsville Beach into the inlet and offshore ebb shoal of the inlet complex was 147,232 cyyr.The sediment transport calculated at the western end of Masonboro Island near Carolina Beach Inlet was 361,493 cyyr to the west, within 2 of the previously estimated rate of 354,000 cyyr USACE 2000 for the area. The sediment transport rate calculated on the eastern end of Wrightsville Beach was 43,427 cyyr toward the east.
