shoaling
Depth gradually decreasing
Shoaling describes water becoming shallower, or the process by which waves change as they approach shallow water.
A shoaling area warns boaters of decreasing depth.
Shoals are shallow places in bodies of water—sandbars, reefs, or other submerged hazards: The ship ran aground on a shoal.
Fish that shoal gather in loose groups, distinguished from the tighter coordination of schooling.
