Soil erosion is the denudation or wearing away of the upper layer of soil. It is a form of soil degradation. ... as well as sediment-related damage to roads and houses.
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). [10]: 60–61 [13] In splash erosion, the impact of a falling raindrop creates a small crater in the soil, [14] ejecting soil particles. [4]
Eroded hilltops due to tillage erosion. Tillage erosion is a form of soil erosion occurring in cultivated fields due to the movement of soil by tillage. [1] [2] There is growing evidence that tillage erosion is a major soil erosion process in agricultural lands, surpassing water and wind erosion in many fields all around the world, especially on sloping and hilly lands [3] [4] [5] A signature ...
The best management approach to these soils is simply to avoid their disturbance. Maintaining vegetation cover of the soil is also important to minimize soil dispersion. [5] In agricultural systems, this may mean making an effort to prevent surface soil loss and/or damage, as the surface soil and ground cover form a protective barrier.
Environmental impact of mining can occur at local, regional, and global scales through direct and indirect mining practices. Mining can cause erosion, sinkholes, loss of biodiversity, or the contamination of soil, groundwater, and surface water by chemicals emitted from mining processes.
Overgrazing typically increases soil erosion. [7]With continued overutilization of land for grazing, there is an increase in degradation. This leads to poor soil conditions that only xeric and early successional species can tolerate. [8]
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.
Internal erosion is the formation of voids within a soil caused by the removal of material by seepage. [1] It is the second most common cause of failure in levees and one of the leading causes of failures in earth dams , [ 2 ] responsible for about half of embankment dam failures.
