Erosion and deposition occur constantly along the sides of a meander, thereby causing the ends of its loop to come closer and closer. In due course of time, the meander loop cuts off from the river and forms a cut-off, crescent-shaped ox-bow lake. WebDetailed explanation of how waterfalls are formed.

River cliffs are features of meanders. In a meander the outside bank is where the Thalweg flows (fastest flowing part of the river), this means the velocity is greatest here so there is more available energy for erosion.

WebWhen a river creates a meander, an oxbow lake is the form it takes after a long period of time. The river creates the meander by erosion of the water.
