What processes give the Gulf coast its distinctive characteristic that is different from the Atlantic and Pacific coasts of the United States?
The Gulf coast experiences a smaller tidal range and a smaller average wave size than either the Pacific or Atlantic coasts. Reduced longshore drift and an absence of interrupting submarine canyons allow the great volume of accumulated sediments from the Mississippi and other rivers to form large deltas, barrier islands, and a long raised "super berm" that prevents the ocean from inundating much of this sinking coast.?
