Sheet erosion or sheet wash is the even erosion of substrate along a wide area. [1] It occurs in a wide range of settings such as coastal plains , hill slopes, floodplains , beaches , [ 2 ] savanna plains [ 3 ] and semi-arid plains. [ 4 ]
Splash erosion is generally seen as the first and least severe stage in the soil erosion process, which is followed by sheet erosion, then rill erosion and finally gully erosion (the most severe of the four). [6] [7] In splash erosion, the impact of a falling raindrop creates a small crater in the soil, [8] ejecting soil particles. [9]

Surface runoff can cause erosion of the Earth's surface; eroded material may be deposited a considerable distance away. There are four main types of soil erosion by water: splash erosion, sheet erosion, rill erosion and gully erosion. Splash erosion is the result of mechanical collision of raindrops with the soil surface: soil particles which ...
Gully erosion may also advance laterally through similar methods, including mass movement, acting on the gully walls (banks), and the development of 'branches' (a type of tributary). Gullies reduce the productivity of farmlands where they incise into the land and produce sediment that may choke downstream waterbodies and reduce water quality ...
Sheetwash or sheet erosion, in which broad sheets of flowing water evenly remove thin layers of surface material without incising channels. [18] [19] Mountain-front retreating by weathering [20] Lateral planation or erosion by a stream [21] Rillwash or rill erosion, in which flow is concentrated in numerous closely spaced minute channels. [19]
The Marburg virus, which causes bleeding from the eyes, nose, and mouth, can be fatal in up to 90% of those infected
The Universal Soil Loss Equation (USLE) is a widely used mathematical model that describes soil erosion processes. [1]Erosion models play critical roles in soil and water resource conservation and nonpoint source pollution assessments, including: sediment load assessment and inventory, conservation planning and design for sediment control, and for the advancement of scientific understanding.
