a form of erosion involving the formation of deep, steep-sided channels or gullies which cannot be removed by cultivation ( see rill erosion, sheet erosion)
A complex of processes whereby the removal of soil is characterised by large incised channels in the landscape. Processes include concentration of large volumes of surface runoff and dispersion of unstable subsoils.
occurs when rills develop to greater depths. Gully erosion usually occurs within 300m of rill erosion.
a form of erosion involving the formation of deep sided channels or gullies usually due to the removal of riparian vegetation.
Forestry Operations & Water Quality] The removal of soil by water running in narrow channels, which may be eroded to depths ranging from 1 to 20 feet to as much as 75 to 100 feet. Related Links
Removal of layers of soil, creating channels or ravines too large to be removed by normal tillage operations.
They are formed when channel development has progressed to the point where the gully is too wide and too deep to be tilled across. These channels carry large amounts of water after rains and deposit eroded material at the foot of the gully. They disfigure landscape and make land unfit for growing crops.
The erosion process whereby water accumulates in narrow channels or depressions which are on an incline and, over short periods, removes the soil from this narrow area to considerable depths, ranging from 1 foot to as much as 100 feet.
Erosion resulting in a relatively deep incision of the soil surface, caused by concentrated overland runoff.
Erosion of soil or soft rock material by running water that forms distinct, narrow channels that are larger and deeper than rills and that usually carry water only during and immediately after heavy rains or following the melting of ice or snow.
A form of catastrophic erosion that forms gullies.
