A cut bank, also known as a river cliff or river-cut cliff, is the outside bank of a water channel (), which is continually undergoing erosion. These may be convex, straight, or concave; the shape of a slope is an expression of the predominant processes acting on it.Convex slope elements are usually gentle, generally at the top of a slope, and formed by soil creep and rainsplash.
