A point bar is a depositional feature made of alluvium that accumulates on the inside bend of streams and rivers below the slip-off slope. Point bars are found in abundance in mature or meandering streams. They are crescent-shaped and located on the inside of a stream bend, being very similar to, though often smaller than, towheads, or river islands.

These levees are recognizable as elongate, narrow ridges adjacent to a channel. Occasionally, river flow breaches a levee, forming a gap in the levee called a crevasse.
