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.
Gully erosion is the removal of soil along drainage lines by surface water runoff. Learn how to prevent and control gully erosion with good land management practices, catchment works and gully stabilisation measures.
Soil erosion is the process of soil degradation due to the action of water, wind, or human activities. Gully erosion is one of the types of soil erosion caused by the runoff of surface water, leading to the removal of soil with drainage lines.
Gully erosion is a form of soil erosion caused by flowing surface water that cuts unstable channels into the ground. It can reduce land, increase flooding, pollute waterways and damage underground utilities. Learn how to prevent and treat gully erosion in New South Wales.
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 (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.
