Answer:
Fluvial Erosional Landforms are landforms created by the erosional activity of rivers.
Various aspects of fluvial erosive action include:
Hydration: the force of running water wearing down rocks.
Corrosion: chemical action that leads to weathering.
Attrition: river load particles striking, colliding against each other and breaking down in the process.
Corrasion or abrasion: solid river load striking against rocks and wearing them down.
Downcutting (vertical erosion): the erosion of the base of a stream (downcutting leads to valley deepening).
Lateral erosion: the erosion of the walls of a stream (leads to valley widening).
Headward erosion: erosion at the origin of a stream channel, which causes the origin to move back away from the direction of the stream flow, and so causes the stream channel to lengthen.

Braiding: the main water channel splitting into multiple, narrower channel. A braided river, or braided channel, consists of a network of river channels separated by small, and often temporary, islands called braid bars. Braided streams occur in rivers with low slope and/or large sediment load.
