  2. Erosion - Wikipedia

    en.wikipedia.org/wiki/Erosion

    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]

    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]

  4. Cycle of erosion - Wikipedia

    en.wikipedia.org/wiki/Cycle_of_erosion

    The geographic cycle, or cycle of erosion, is an idealized model that explains the development of relief in landscapes. [1] The model starts with the erosion that follows uplift of land above a base level and ends, if conditions allow, in the formation of a peneplain . [ 1 ]

  5. Denudation - Wikipedia

    en.wikipedia.org/wiki/Denudation

    Denudation incorporates the mechanical, biological, and chemical processes of erosion, weathering, and mass wasting. Denudation can involve the removal of both solid particles and dissolved material. These include sub-processes of cryofracture, insolation weathering, slaking, salt weathering, bioturbation, and anthropogenic impacts. [4]

  6. Headward erosion - Wikipedia

    en.wikipedia.org/wiki/Headward_erosion

    Headward erosion is a fluvial process of erosion that lengthens a stream, a valley or a gully at its head and also enlarges its drainage basin. The stream erodes away at the rock and soil at its headwaters in the opposite direction that it flows. Once a stream has begun to cut back, the erosion is sped up by the steep gradient the water is ...

  7. Hjulström curve - Wikipedia

    en.wikipedia.org/wiki/Hjulström_curve

    The upper curve shows the critical erosion velocity in cm/s as a function of particle size in mm, while the lower curve shows the deposition velocity as a function of particle size. Note that the axes are logarithmic. The plot shows several key concepts about the relationships between erosion, transportation, and deposition.

  8. Surface and bulk erosion - Wikipedia

    en.wikipedia.org/wiki/Surface_and_bulk_erosion

    A diagram showing surface erosion (left) and bulk erosion (right). In surface erosion, the material only degrades on the surface which causes the material to “shed off” its surface over time. In bulk erosion, the material loses volume throughout equally, which is represented by the fading colors.

  9. 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 ...
