A river may erode by the processes of corrosion, attrition, corrasion or hydraulic power. For hydraulic power describe how it works

•It forms where a river channel erodes through the neck of two meander bends that are eroding towards each other. The river then flows more directly and is diverted away form the meander bend. The neck is then sealed off from the rest of the river channel through deposition, leaving a arc shaped lake isolated from the rest of the river.
