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”.
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.
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)
Gully erosion is localized in the Coastal Plain Sands, Nanka Sands, and Nsukka Sandstone of the Anambra-Imo basin region. The most affected deposits are unconsolidated or poorly consolidated and have short dispersion times.
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.
Jan 1, 2003 · Recent studies indicate that (1) gully erosion represents an important sediment source in a range of environments and (2) gullies are effective links for transferring runoff and sediment from uplands to valley bottoms and permanent channels where they aggravate off site effects of water erosion.
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.
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...
Gully erosion is a formidable land degradation process globally. It is omnipresent. across India, wherein two of the largest badlands regions in the world also exist. However, despite being affected by widespread gullying, gully erosion research in. India has been rather limited, with key aspects of gully formation, morphologies and.
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.
