Notice in the December 1992 map that two inlets were eroded through the barrier island during the storm, but by March, the western inlet had closed with newly deposited sediment while the eastern inlet became larger
Explain why one inlet closed while the other enlarged.
What will be an ideal response?
The longshore current flows from northeast to southwest. Waves eroding sediment along the edge of the eastern inlet provided sediment that moved to the southwest where it was deposited too close in the western inlet. The eastern inlet was closer to the groins than the western inlet, so the eastern inlet was not receiving sediment from currents moving along the shoreline from the northeast.
