Abstract

Analysis of shoreline changes at four unjettied inlets on the developed New Jersey shoreline reveals that shorelines have been less mobile under conditions of development than they were prior to development. Bulkheads reduce the amount of shoreline change by preventing breaches in the barrier islands updrift of inlets and by restricting the amount of shoreline retreat that occurs during natural cycles of erosion and accretion. Groins reduce the rate of transport into downdrift shorelines which dampens the accretion phase of the cycles. Maintenance dredging can suppress the cycles by keeping the ebb channel position from fluctuating as widely as it would under natural conditions. The projection of future shoreline change at these four tidal inlets reflects either unidirectional change or stability at locations that formerly were characterized by cyclic change.
