  2. Soil erosion - Wikipedia

    en.wikipedia.org/wiki/Soil_erosion

    Soil erosion is the denudation or wearing away of the upper layer of soil. It is a form of soil degradation . This natural process is caused by the dynamic activity of erosive agents, that is, water , ice (glaciers), snow , air (wind), plants , and animals (including humans ).

  3. Erosion - Wikipedia

    en.wikipedia.org/wiki/Erosion

    It shelters the soil from winds, which results in decreased wind erosion, as well as advantageous changes in microclimate. The roots of the plants bind the soil together, and interweave with other roots, forming a more solid mass that is less susceptible to both water [64] and wind erosion. The removal of vegetation increases the rate of ...

  4. Tillage erosion - Wikipedia

    en.wikipedia.org/wiki/Tillage_Erosion

    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 ...

  5. Coastal erosion - Wikipedia

    en.wikipedia.org/wiki/Coastal_erosion

    Over time the coast generally evens out. The softer areas fill up with sediment eroded from hard areas, and rock formations are eroded away. [4] Also erosion commonly happens in areas where there are strong winds, loose sand, and soft rocks. The blowing of millions of sharp sand grains creates a sandblasting effect. This effect helps to erode ...

  6. Soil retrogression and degradation - Wikipedia

    en.wikipedia.org/wiki/Soil_retrogression_and...

    Soil regeneration is the reformation of degraded soil through biological, chemical, and or physical processes. [ 2 ] When productivity declined in the low-clay soils of northern Thailand, farmers initially responded by adding organic matter from termite mounds , but this was unsustainable in the long-term.

  7. Bank erosion - Wikipedia

    en.wikipedia.org/wiki/Bank_erosion

    There are two primary mechanisms of stream bank erosion: fluvial erosion and mass failure. Fluvial erosion is the direct removal of soil particles by flowing water. The rate of fluvial erosion is determined both by the force of the flowing water (e.g. faster flow equals more force) and the resistance of the bank material to erosion (e.g. clay is generally more resistant to erosion than sand).

  8. Rill - Wikipedia

    en.wikipedia.org/wiki/Rill

    Rills are created when fire erodes the soil topsoil on hillsides and so are significantly affected by seasonal weather patterns. They tend to appear more often in rainier months. [ 1 ] Rills begin to form when the runoff shear stress , the ability of surface runoff to detach soil particles, overcomes the soil's shear strength, the ability of ...

  9. River bank failure - Wikipedia

    en.wikipedia.org/wiki/River_bank_failure

    Three main types of vegetation exist to prevent bank failure: Trees, shrubs, and grasses. Trees will provide for deep and dense root systems, increasing the stresses a river bank will accommodate. Shrubs are staked into the river bank in order to provide a protective covering against erosion, creating good plant coverage and soil stability. [3]
