- Erosional and Depositional
- Meanders are large bends in a river.
- The current is faster on the outside of the bend as the water is deeper.
- This means that more erosion in those area, this forms river cliffs.
- The current is slower on this inside of the bends as the water is more shallow; this means there's more friction to slow down the water.
- Eroded material is deposited on the inside of the bend, this form slip-off slopes
- Ox-Bow lakes are formed from meanders; meanders get larger over time.
- Erosion causes the outside bends to become closer untill there is only a small gap between the bends (the neck).
- Eventually, the river breaks through the land, usually during a flood, and the rive flows along the shortest course.
- Deposition eventually cuts off the meander forming an ox-bow lake.
