Gully erosion is the removal of soil along drainage lines by surface water runoff. When rills (small channels formed by water flow) increase in size, they become gullies.
- When a gully bed is eroded further due to headward erosion, it gradually deepens and flattens out, forming a ravine. Ravines can be quite deep, extending to 30 meters or more.
- Over a large area, gully formation can lead to badland topography, characterized by irregular and deeply eroded landscapes.
Rajasthan : Chambal and its tributaries have considerably eroded the Hadauti plateau. Kota, Sawai Madhopur, and Dholpur districts have suffered from gully erosion.
