NAGS HEAD RENOURISHMENT - PLANNING, DESIGN, AND NUMERICAL MODELING
AbstractThe 16 kilometer (km) beach along Nags Head (North Carolina, USA) has sustained chronic erosion over the past 50 years. In 2011, 3.5 million cubic meters (m3) of beach-quality sand was dredged from offshore and placed along the oceanfront at fill densities ranging from 150 m3/m to 400 m3/m (averages 220 m3/m). It is the largest locally funded beach nourishment project completed to date in the U.S. Following successful completion of the project, the Town of Nags Head monitored performance and developed strategies for beach maintenance and preservation with the goal of improving protection to all properties and recreational beach area. The short-term plan is a renourishment anticipated to commence in the summer of 2018 or before the 2011 project reaches 50% fill remaining. The long-term plan targets a timeframe of 30 years. This abstract will focus on the short-term plan whose original purpose and goals are to supplement and enhance the initial 2011 project.
