Types of Water Erosion
- Splash Erosion: Small soil particles are detached and sent airborne through the impact of raindrops on soil.
- Sheet Erosion: Raindrops break apart the soil structure and it's moved downslope by water that flows overland as a sheet rather than definitive channels. This occurs frequently during cloud bursts.
- Rill Erosion: This process develops small, short-lived, concentrated flow paths. These paths creates a sediment source and delivery system for hillslope erosion. Areas where precipitation rates exceed soil infiltration rates are more prone to this type of erosion.
- Gully Erosion: Water flows in narrow channels during or directly following heavy rains or melting snow. The gullies can erode to considerable depths.
- Valley or Stream Erosion: Continual water flow alongside land (along a linear feature) creates this type of erosion. It extends downward, deepening a valley, and headward, extending the valley into the hillside. This occurs most frequently in times of flooding.
- Bank Erosion: Over time, banks of rivers and streams are naturally worn down.
