Erosion enlarges the channel, while lateral erosion becomes increasingly important. This sideways erosion helps widen the valley and develop meanders, or bends, in the channel. Valley sides become gentler and floodplains develop beside the river.
Erosion of a river’s banks that widens the channel and valley.
Specification 3.2a · Paper 1, Paper 3
The wearing away of a river's banks, widening its channel and helping bends move sideways.
Revise: River Landforms: Erosional and Depositional FeaturesLateral erosion wears away the banks, allowing the river to widen its channel and move sideways across its valley. This becomes more important in lowland areas. Deposition occurs when the flow slows and can no longer carry as much sediment.
