Depending upon whether a meander is part of an entrenched river or part of a freely meandering river within a floodplain, the term slip-off slope can refer to two different fluvial landforms that comprise the inner, convex, bank of a meander loop. In case of a freely meandering river on a floodplain, a slip-off slope is the inside, gently ...
A river constantly evolves and as it does, meanders that were once a part of the river are abandoned in favor of a route that is more efficient for a river to take. As these old meanders are cutoff from the rest of the river, a new channel, or cutoff channel, is formed. Neck cutoff: a river bend intersects itself.
Point bars are typically found in the slowest moving, shallowest parts of rivers and streams, [5] and are often parallel to the shore and occupy the area farthest from the thalweg, [6] on the outside curve of the river bend in a meandering river. Here, at the deepest and fastest part of the stream is the cut bank, the area of a meandering river ...
Point bar at a river meander: the Cirque de la Madeleine in the Gorges de l'Ardèche, France. Any fluid, including water in a stream, can only flow around a bend in vortex flow. [ 1 ] In vortex flow the speed of the fluid is fastest where the radius of the flow is smallest, and slowest where the radius is greatest.
River Ashes Hollow, UK. Schematic cross section of a meandering river channel showing slip-off slope formation. A slip-off slope is a depositional landform that occurs on the inside convex bank of a meandering river. The term can refer to two different features: one in a freely meandering river with a floodplain and the other in an entrenched ...
A cut bank, also known as a river cliff or river-cut cliff, is the outside bank of a curve in a water channel , which is continually undergoing erosion. [1] Cut banks are found in abundance along mature or meandering streams, they are located opposite the slip-off slope on the inside of the stream meander.

An entrenched river, or entrenched stream is a river or stream that flows in a narrow trench or valley cut into a plain or relatively level upland. Because of lateral erosion streams flowing over gentle slopes over a time develops meandering (snake like pattern) course. Meanders form where gradient is very gentle, for example in floodplain and ...
