What is a coastal cell? Where does sand in a coastal cell come from? Where does it go?

Expert Solution
To determine

A coastal cell and the place from which the sand reaches coastal cell and the place where it goes.

Explanation of Solution

Rivers bring most of the new sand to the coast. The longshore drift moves the sand parallel to the beach, and as the season’s changes. The sand moves onshore and offshore at right angles to the beach. If the size of the beach is stable, which means it neither grows nor shrinks, the quantity of new sand that enters the coast should balance the quantity of old sand that is removed from the coast.

Sand that glides beneath the reach of the waves are lost from the coast and moves further out on the continental shelf. Longshore current moves some sand into the nearshore heads of submarine canyons. The sand that moves away from the coast in the canyons sometimes makes sand fall...
