Ebb-Tidal Delta Development Where Before There was None, Shark River Inlet, New Jersey
Abstract
The navigation channel at Shark River Inlet, NJ, is the responsibility of the U.S. Army Corps of Engineers, New York District. Until about the year 2000, the ocean entrance to Shark River Inlet required minor, infrequent maintenance dredging (every 7 to 10 years). Following large-scale beach nourishment to this stretch of coast in the late 1990s, the hydraulically efficient inlet began to experience rapid shoaling at the entrance. Subsequent to year 2000, surveys by the New York District indicated increased shoaling at the inlet entrance, first from the south and then from the north necessitating unplanned dredging to maintain the navigation channel. To maintain the authorized entrance channel navigable depth of 5.5 m below MLW, dredging must now be done semi-annually in addition to the planned operational 2-3 year dredging cycle. A study was performed to understand and quantify the reasons for change in the inlet morphology and increased channel shoaling, and to predict the consequences of future engineering actions for reducing or controlling the shoaling. Formation and growth of an ebb-tidal delta at the entrance subsequent to the beach nourishment is documented before which there was none.
