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]
Erosion of mountains massifs can create a pattern of equally high summits called summit accordance. [73] It has been argued that extension during post-orogenic collapse is a more effective mechanism of lowering the height of orogenic mountains than erosion. [74] Examples of heavily eroded mountain ranges include the Timanides of
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.
The erosion associated with overland flow may occur through different methods depending on meteorological and flow conditions. If the initial impact of rain droplets dislodges soil, the phenomenon is called rainsplash erosion. If overland flow is directly responsible for sediment entrainment but does not form gullies, it is called "sheet erosion".
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 ...
This talus accumulation is an example of colluvium. Colluviation refers to the buildup of colluvium at the base of a hillslope. [1] [2] Colluvium is typically loosely consolidated angular material located at the base of a steep hill slope or cliff. Colluvium accumulates as gently sloping aprons or fans, either at the base of or within gullies ...
Erosion control is the practice of preventing or controlling wind or water erosion in agriculture, land development, coastal areas, river banks and construction. Effective erosion controls handle surface runoff and are important techniques in preventing water pollution , soil loss , wildlife habitat loss and human property loss.
