Types of Soil Erosion by water

Rainsplash and water running over the soil surface detach and transport the detached soil particles.

This encompasses the following processes: 

Rainsplash: 

The soil particles are displaced by raindrop impact. (No changes were made to the original photo. source: unknown).

Sheet erosion: 

Water running as a shallow sheet (overland flow) and displacing a relatively uniform thickness of soil. (No changes were made to the original photo. © Jannes Stolte/NIBIO).

 Rill erosion:  

This refers to water moving as concentrated flow and removing soil by “digging out” channels, resulting in small rills formed by concentrated water flow. (No changes were made to the original photo. © Jannes Stolte/NIBIO). 

Gully erosion: 

Severe cases of rill leading to the formation of gullies that are either temporary (left) or permanent (right). (No changes were made to the original photo. © Jannes Stolte/NIBIO).
