Abstract : This report documents a desk study performed to identify factors responsible for accelerated sand shoaling at the federally maintained entrance channel to Shark River Inlet, NJ. Since the late 1990s, channel maintenance dredging requirements at the inlet have increased. The study was proceeded by review of the engineering literature, analysis of channel and nearshore bathymetry surveys, and application of general principles of coastal and inlet processes. Although Shark River Inlet possesses a small back bay, the current through the inlet is strong because of the narrow width between jetties. In the past century, this coast was sand deficient. With recent beach nourishment projects as part of an erosion-control program, the longshore sand transport potential along the coast is becoming realized, allowing an ebb-tidal shoal to form at the entrance. This shoal is expected to increase in volume over the next two decades to reach about 1.2 million cubic yards. Therefore, the dredging maintenance strategy must transition to one similar to those at other small tidal inlets along the Atlantic Ocean coasts of New Jersey and New York.
