Question

Coastal Change after 1933 Hurricane After the 1933 hurricane carved out Ocean City Inlet, the Army Corps of Engineers constructed a pair of jetties on each side of the inlet to keep it open. The southern jetty is labeled "seawall" on the map. Sand filled in behind the northern jetty, so it is now a seawall forming the straight southern limit of Fenwick Island (a straight black line on the map). After reading the information above and observing the maps, would you say that the longshore current is traveling north to south, or south to north along the shore?

Answer 1

Longshore Current is travelling from north to south.

1. Because sands are deposited behind the northern jetty as shown in the map, if it goes south to north then it is deposited behind the southern jetty.
