  2. Erosion - Wikipedia

    en.wikipedia.org/wiki/Erosion

    Erosion and changes in the form of river banks may be measured by inserting metal rods into the bank and marking the position of the bank surface along the rods at different times. [23] Thermal erosion is the result of melting and weakening permafrost due to moving water. [24] It can occur both along rivers and at the coast.

  3. Soil erosion - Wikipedia

    en.wikipedia.org/wiki/Soil_erosion

    Erosion and changes in the form of river banks may be measured by inserting metal rods into the bank and marking the position of the bank surface along the rods at different times. [17] Thermal erosion is the result of melting and weakening permafrost due to moving water. [18] It can occur both along rivers and at the coast.

  4. Coastal erosion - Wikipedia

    en.wikipedia.org/wiki/Coastal_erosion

    Coastal erosion is the loss or displacement of land, or the long-term removal of sediment and rocks along the coastline due to the action of waves, currents, ...

  5. Bank erosion - Wikipedia

    en.wikipedia.org/wiki/Bank_erosion

    Bank erosion is natural, but can be accelerated by humans. Bank erosion is the wearing away of the banks of a stream or river. This is distinguished from erosion of the bed of the watercourse, which is referred to as scour. The roots of trees growing by a stream are undercut by such erosion. As the roots bind the soil tightly, they form ...

  6. Denudation - Wikipedia

    en.wikipedia.org/wiki/Denudation

    Denudation is the geological process in which moving water, ice, wind, and waves erode the Earth's surface, leading to a reduction in elevation and in relief of landforms and landscapes.

  7. Surface runoff - Wikipedia

    en.wikipedia.org/wiki/Surface_runoff

    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 ...

  8. Erodibility - Wikipedia

    en.wikipedia.org/wiki/Erodibility

    Erodability (or erodibility) is the inherent yielding or nonresistance of soils and rocks to erosion. A high erodibility implies that the same amount of work exerted by the erosion processes leads to a larger removal of material. Because the mechanics behind erosion depend upon the competence and coherence of the material, erodibility is ...

  9. Downcutting - Wikipedia

    en.wikipedia.org/wiki/Downcutting

    Downcutting, also called erosional downcutting, downward erosion or vertical erosion, is a geological process by hydraulic action that deepens the channel of a stream or valley by removing material from the stream's bed or the valley's floor. The speed of downcutting depends on the stream's base level, the lowest point to which the stream can ...
