Gully erosion (Fig. 6) occurs where concentrated surface water scour out the regolith and underlying rock with the debris being either deposited downslope or transported into river systems creating major downstream problems. The gully form and severity is very dependent on the rock type.

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. Excessive clearing, inappropriate land use and compaction of the soil ...
In most cases gullies can be prevented by good land management practices aimed at maintaining even infiltration rates and a good plant cover. Strategies for preventing gully erosion include: 1. maintaining remnant vegetation along drainage lines and eliminating grazing from these areas 2. increasing water usage by planting deep-rooted perennial pas...
To be effective, gully control needs to be tackled in two ways: 1. fixing the problems in the catchment 2. stabilising the gully itself.
Don't fill eroded gullies with solid objects such as old drums, car bodies or concrete. This only creates further erosion by directing water around such objects and removing more soil.
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]
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.

Oct 16, 2023 · Gully erosion is a highly visible form of soil erosion which can indicate an imbalance in regular watercourse flow. Larger (and faster) than normal water flows cause steep-sided watercourses which then widen further during periods of heavy rainfall.
Gully erosion develops primarily due to concentrated water runoff during heavy rainfall or rapid snowmelt, especially in areas lacking vegetation. It differs from other forms of soil erosion, like rill erosion, which involves smaller channels that may be less damaging.
Oct 31, 2005 · Gully erosion has been long neglected because it is difficult to study and to predict. Gully processes have a three-dimensional nature affected by a wide array of factors and processes.
