Cut bank

Outside bank of a water channel, which is continually undergoing erosion

A cut bank, also known as a river cliff or river-cut cliff, is the outside bank of a curve (meander) in a water channel (stream), which is continually undergoing erosion. Cut banks occur on the outer side of meander bends, opposite the point bar or slip-off slope on the inner side. They are shaped much like a small cliff, and are formed as the stream collides with the river bank.
