Definition
- Fluvial landforms are those generated by running water, mainly rivers.
Process Involved
- Hydration: The force of running water wearing down rocks.
- Corrosion/Solution: Chemical action that leads to weathering.
- Attrition: It involves wear & tear of transported material among them when they roll and collide with one another.
- Corrosion 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.
- Hydraulic Action: It involves Mechanical loosening & sweeping away of materials by river water. It occurs mainly by surging into the crevices & cracks of rocks & disintegrating them.
- Braiding: The main water channel splits into multiple, narrower channels.
