How do oxbows formed

Over time, continual erosion and deposition narrows the neck of the meander. Often during a flood the river will cut through the neck of the meander. The river continues on its straighter path and the meander is abandoned.

This animation shows how an oxbow lake is formed, step by step. The water flows fastest around the outside of the bend. The fast-flowing water cuts away the outer bank. This is called erosion. The river carries sediment, which contains particles of rock and sand, as it flows toward the sea.

The slow moving water drops sediment on the inner bank. This is called deposition. Over time, this action makes the curve get bigger and turns it into a meander.
