Gully erosion is a major soil degradation problem in many parts of the world. Assessment of this process and its contributing factors are becoming increasingly important, especially in terms of climate change. Rainfall runoff is known to initiate and exacerbate gully erosion processes. In this paper, research over the past two decades focussing ...

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.
Oct 31, 2005 · The objective of this paper is to review recent studies on impacts, factors and control of gully erosion and update the review on ‘gully erosion and environmental change: importance and research needs’ [Poesen et al., 2003. Catena 50 (2–4), 91–134.]. For the farmers, the development of gullies leads to a loss of crop yields and ...

Nov 9, 2020 · In turn, these are controlled by external forcing factors that can be grouped into (i) geomorphology and topography, (ii) climate and (iii) the bio-physical environment. The impact of gully prevention and control techniques is addressed, especially regarding their effect on headcut retreat and network development, the trapping of sediment by ...

Gully erosion occurs when running water erodes soil to form channels deeper than 30cm. Gullies start when fast flowing runoff hits a ‘nick’ point such as a rabbit burrow, root hole, stock/vehicle track, or bare soil. The energy of the water scours away the soil, undermining the vegetation. Once the vegetation and topsoil are removed ...

Gully erosion is a form of soil erosion that occurs when water runoff creates deep, narrow channels in the landscape, often leading to significant loss of soil and degradation of land. This type of erosion typically arises in areas with intense rainfall or where vegetation has been removed, allowing water to concentrate and flow more forcefully, carving out channels over time.

Jan 1, 2003 · Consequently, there is a need for monitoring, experimental and modelling studies of gully erosion as a basis for predicting the effects of environmental change (climatic and land use changes) on gully erosion rates. In this respect, various research questions can be identified. The most important ones are:
