Detailed Description

Big storms move sediment from the front of the barrier to the top and the back of the barrier through a process called overwash. In addition to causing a lot of overwash, Hurricane Sandy also cut through (breached) the island in two places on Island Beach near Mantoloking, NJ, resulting in deposition (shown in green shades) in the estuary.
