The Soil Conservation Society of America defines a gully as “a channel or miniature valley cut by concentrated runoff but through which water commonly flows only during and immediately after heavy rains. It may be dendritic or branching or it may be linear, rather long, narrow and of uniform width”.
Oct 31, 2005 · Gully erosion is not a process limited to badlands, mountainous and hilly regions but a global and serious cause of land degradation affecting a wide variety of soils prone to crusting and/or piping. (2) Gully erosion results not only from surface flow but also often from sub-surface flow. (3)
Jul 1, 2021 · In this review we discuss the relevance and need of assessing gully erosion at regional to continental scales (Section 1); current methods to monitor gully erosion as well as pitfalls and opportunities to apply them at larger scales (section 2); field-based gully erosion research conducted in Europe and European Russia (section 3); model ...
Sep 1, 2016 · Gully erosion has been recognised throughout history as a major land degradation process (Dotterweich et al., 2012), and in many cases has been directly linked to unsustainable land management.
Gully erosion is a widespread and often dramatic form of soil erosion caused by flowing surface water. It consists of open, unstable channels that have been cut more than 30 centimetres deep into the ground. Gully erosion is a result of the interaction of land use, climate and slope.
Gully, trench cut into land by the erosion of an accelerated stream of water. Various conditions make such erosion possible: the natural vegetation securing the soil may have been destroyed by human action, by fire, or by a climatic change; or an exceptional storm may send in torrents of water down.
Gullies are caused by concentrated flows, either from field runoff and small rills combining together into larger flows or from runoff coming onto the field from a concentrated source.
Sep 30, 2021 · This chapter presents the classification and geomorphic features of gullies, spatial variability of soil shear strength within the gullies, major erosion processes and controlling factors of gully development, gully erosion susceptibility, and sediment production by...
Nov 9, 2020 · Gully erosion is a major environmental problem, posing significant threats to sustainable development. However, insights on techniques to prevent and control gullying are scattered and incomplete, especially regarding failure rates and effectiveness.
A gully is a landform created by running water, mass movement, or commonly a combination of both eroding sharply into soil or other relatively erodible material, typically on a hillside or in river floodplains or terraces. [1] .
