A meandering stream migrates laterally by sediment erosion on the outside of the meander (that is part of the friction work), and deposition on the inside (helicoidal flow, deceleration, channel lag, point bar sequence, fining upwards). A lake forms as the river finds a different, shorter, course. Meanders change position by eroding sideways and slightly downstream. New deposition seals off the ends and the cut-off becomes an oxbow lake that will eventually dry up. This process reinforces the riffle-pool structure of a stream.

Just after the cutoff meander is formed, the river flows into its end from the river and builds a small delta which eventually results in the formation of oxbow lakes. One method of lateral erosion is hydraulic action, where the sheer force of the water smashes against the river bank causing it to erode.However, the river changes over time also due to deposition. Oxbow lakes form when one meander erodes into another, cutting off water to part of the stream channel. Find out more about meanders and oxbow lakes.
