- Gully erosion – when water runoff removes soil along drainage lines.
- Ephemeral erosion that occurs in natural depressions.
What is soil erosion What are its causes and effects?
Soil erosion is a
gradual process of movement and transport of
the upper layer of soil (topsoil) by different agents – particularly water, wind, and mass movement – causing its deterioration in the long term.
