    en.wikipedia.org/wiki/Colluvium

    Erosion on Koh Tao Island. Colluvium (also colluvial material or colluvial soil) is a general name for loose, unconsolidated sediments that have been deposited at the base of hillslopes by either rainwash, sheetwash, slow continuous downslope creep, or a variable combination of these processes.

  3. Soil erosion - Wikipedia

    en.wikipedia.org/wiki/Soil_erosion

    Dobbingstone Burn, Scotland—This photo illustrates two different types of erosion affecting the same place. Valley erosion is occurring due to the flow of the stream, and the boulders and stones (and much of the soil) that are lying on the edges are glacial till that was left behind as ice age glaciers flowed over the terrain.

  4. Erodibility - Wikipedia

    en.wikipedia.org/wiki/Erodibility

    Soil erodibility is a lumped parameter that represents an integrated annual value of the soil profile reaction to the process of soil detachment and transport by raindrops and surface flow. [1] The most commonly used model for predicting soil loss from water erosion is the Universal Soil Loss Equation (USLE) (also known as the K-factor ...

    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]

    Soil color, while easily discerned, has little use in predicting soil characteristics. [109] It is of use in distinguishing boundaries of horizons within a soil profile, [ 110 ] determining the origin of a soil's parent material , [ 111 ] as an indication of wetness and waterlogged conditions, [ 112 ] and as a qualitative means of measuring ...

  7. Universal Soil Loss Equation - Wikipedia

    en.wikipedia.org/wiki/Universal_Soil_Loss_Equation

    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.

  9. Soil retrogression and degradation - Wikipedia

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

    Soil erosion is the main factor for soil degradation and is due to several mechanisms: water erosion, wind erosion, chemical degradation and physical degradation. Erosion can be influenced by human activity. For example, roads which increase impermeable surfaces lead to streaming and ground loss.
