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.
Gully erosion occurs when water is channelled across unprotected land and washes away the soil along the drainage lines. Under natural conditions, runoff is moderated by vegetation, which generally holds the soil together, protecting it from excessive runoff and direct rainfall.
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.
Erosion occurs when farming practices are not compatible with the soil and land slope limitations such as non-cohesive soils and steeper land slopes that make the soil more prone to be washed away or blown away. These practices are: Overstocking and overgrazing.
Gully erosion is one of the most important types of water erosion that causes the destruction of agricultural and range lands in arid and semiarid areas.
Jan 1, 2003 · Gully erosion is defined as the erosion process whereby runoff water accumulates and often recurs in narrow channels and, over short periods, removes the soil from this narrow area to considerable depths.
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)
Sep 5, 2022 · noun. : soil erosion produced by running water. Examples of gully erosion in a Sentence. Recent Examples on the Web Schwarzmann and Berghoff call the search for visible signs of pollution such as gully erosion — as opposed to measuring water pollutants — an unscientific way to evaluate logging’s impact. Tanka Dhakal, Journal Sentinel, 5 Sep. 2022.
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.
Gully Erosion. Gully erosion occurs due to the runoff of surface water, causing the removal of soil with drainage lines. Gullies when started once, will move by headward erosion or even by slumping of side walls unless and un-till proper steps will be taken in order to stabilize the disturbance.
