Beach Nourishment Episodes at the Sandy Hook Unit, Gateway National Recreation Area, New Jersey, USA: A Preliminary Comparison

Abstract:

A chronic erosion problem at Sandy Hook resulted in two major beach nourishment operations during the 1980's, employing material dredged from nearby navigation channels. Grain size analyses indicate that the emplaced material was similar in both cases. Volumetric estimates based on profile data show that erosion losses following the two projects were comparable, and exceeded historic rates reported for the site. A trend toward increasing rates of erosion was noted. Because beach nourishment does not treat the underlying causes of erosion at this site, it should be viewed as a maintenance action rather than a solution to the problem.
