meanders



The migration of two adjacent, concave bands may narrow the floodplain between them, and the restriction is a ‘meander neck’. This widens out to form a bulbous feature, the ‘meander core’, around which the river swings. The surface of a core may show ‘meander scrolls’, which are low, curved ridges of relatively coarse material lying parallel to the main channel and deposited by the stream.
