A channel bar of mud to coarse conglomerate forming on the convex side of a channel bend due to reduced flow velocity. This landform is the most common type of lateral accretion; a depositional alluvial landform on and behind the convex bank of meandering streams. It is formed and modified as the stream floods and the meander bend moves. Over a period of years point bars expand laterally as the opposite bank is continually eroded backward. The bars progressively spread across the valley bottom, usually as a thin sheet of sand or gravel containing layers that dip into the channel bottom.
