A meander scar, occasionally meander scarp,[1] is a geological feature formed by the remnants of a meandering water channel. They are characterized by "a crescentic cut in a bluff or valley wall, produced by...a meandering stream."[2][3][4] They are often formed during the creation of oxbow lakes.[5][6][7]

The term itself may refer alternatively to the actual cuts into the bank of a bluff,[1] or to the general feature of a drying or dried meander.[5] Both uses, however, describe features of the same process.

Meander scars are caused by the varying velocities of current within the river channel. Due to higher velocity current on the outer banks of the river through the bend, more

wetlands.[8]
