Modeling regional sediment transport and barrier elongation on Long Island coast, United States

• A new numerical model of regional sediment transport and barrier elongation, supplied by sediment coming from longshore sediment transport (LST), was developed. The spit growth and barrier elongation model was based on the model proposed by Kraus (1999). The LST rate used as input for the spit growth and barrier elongation model was simulated by the one-line model of shoreline change (Hanson, 1987) combined with the inlet reservoir model (Kraus, 2000; Larson et al., 2006). The model was applied to field data from the south coast of Long Island, United States. The simulation results were compared with measurements of the annual net LST rate and the barrier elongation. Overall, the model simulations were in good agreement with the measured data. © 2011 ASCE.
