  2. Gully - Wikipedia

    en.wikipedia.org/wiki/Gully

    Gully erosion can progress through a variety and combination of processes. The erosion processes include incision and bank erosion by water flow, mass movement of saturated or unsaturated bank or wall material, groundwater seepage - sapping the overlying material, collapse of soil pipes or tunnels in dispersive soils, or a combination of these ...

  3. Soil erosion - Wikipedia

    en.wikipedia.org/wiki/Soil_erosion

    Gully erosion occurs when runoff water accumulates and rapidly flows in narrow channels during or immediately after heavy rains or melting snow, removing soil to a considerable depth. [12] [13] [14] Another cause of gully erosion is grazing, which often results in ground compaction. Because the soil is exposed, it loses the ability to absorb ...

  4. 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]

    en.wikipedia.org/wiki/Glossary_of_landforms

    Gulch – Deep V-shaped valley formed by erosion; Gully – Landform created by running water and/or mass movement eroding sharply into soil; Hogback – Long, narrow ridge; Hoodoo – Tall, thin spire of relatively soft rock usually topped by harder rock; Homoclinal ridge – Ridge with a moderate sloping backslope and steeper frontslope

  6. Ravine - Wikipedia

    en.wikipedia.org/wiki/Ravine

    A ravine is the final step in gully erosion, formed when a stream has eroded so severely it forms a deep cut in the earth. [3] A gully can be classified as a ravine after it reaches a large depth, typically in excess of 5 metres (16 ft). [4]

  7. 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 ...

  9. Rill - Wikipedia

    en.wikipedia.org/wiki/Rill

    The erosion created by these forces increases the size of the rill while also swelling its output volume. [ 6 ] Less commonly, dissolution of limestone and other soluble rocks by slightly acidic rainfall and runoff also results in the formation of rill-like features on the surface of the rock.
