Interactive visualization of channel shape and velocity.
Upper Course
- Gradient: Steep
- Main Process: Vertical Erosion
- Landforms: V-shaped valleys, waterfalls, gorges, interlocking spurs
- Channel: Narrow, shallow, high friction
Types of River Erosion
Hydraulic Action
The force of the water breaks rock particles away from the river channel.
Abrasion (Corrasion)
Rocks carried along by the river wear down the river bed and banks like sandpaper.
Attrition
Rocks being carried by the river smash together and break into smaller, smoother, rounder particles.
Solution (Corrosion)
Soluble particles are dissolved into the river water (e.g., limestone or chalk).
