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 one of the most important types of water erosion that causes the destruction of agricultural and range lands in arid and semiarid areas.
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.

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)
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.
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.
affected by gully erosion include the foothills of the Lesser Himalayas (Siwaliks) in the northwest and the Chhotanagpur Plateau and sur-roundings in Eastern India (Ahmad, 1973, p. 44; Haigh, 1984) (Figure 1). Gullies and badlands occur in a multitude of soilscapes in India (Figure 1 insets).
a process in which soil, stone, etc. is gradually damaged and removed from the surface of the ground by the running water of a river, stream, etc., or the result of this action: Stretches of the valley have been carved up by gully erosion. We stopped at the top of the mountain, noting on the way the gully erosion typical of the area. Compare.
