Abstract

A cross-shore shoreline change model has been applied to the New Jersey coastline to provide predictions of regional shoreline position on timescales ranging from short-duration storm events to longer term seasonal fluctuations. The model relies on environmental input from readily available sources such as wave buoys and water level gauges, and is based on conservation of volume arguments and equilibrium beach profile theory. The model responds exponentially with time to variances in the equilibrium shoreline position, and the rate at which the shoreline approaches equilibrium is determined by a coefficient that is modified based on whether the profile is accreting or eroding. Eight parameterizations of the rate coefficient were investigated, as well as various methods for predicting erosion vs. accretion. The coefficients were calibrated to shoreline position data collected in Mantoloking, NJ. The study results show that the model can be used to predict shoreline position with a minimum mean absolute error of 3.53 m and a maximum correlation coefficient of 0.8104.
