May 17, 2024 · The Basics of Rill Erosion. Contrastingly, rill erosion is less severe and is characterized by the formation of small, shallow channels on sloping land. These channels, usually about a few inches deep, form when surface water runoff erodes the soil. Rill erosion is often the precursor to more severe gully erosion if not addressed early.

Gully erosion may also advance laterally through similar methods, including mass movement, acting on the gully walls (banks), and the development of 'branches' (a type of tributary). Gullies reduce the productivity of farmlands where they incise into the land and produce sediment that may choke downstream waterbodies and reduce water quality within the drainage system and lake or coastal system.
What factors contribute to the development of gully erosion, and how does it differ from other forms of soil erosion? 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 ...
Land management practices like contour farming and re-vegetation can help mitigate gully erosion by reducing runoff and stabilizing the soil. Unlike rill erosion, which involves smaller channels that can be easily repaired, gully erosion typically requires more extensive intervention to restore the affected area.
1. Check whether the erosion is active Gully erosion can look dramatic, but if the gully has stabilised it may be better to leave it alone. Disturbing dispersive soils may reactivate the gully and cause more erosion. To check whether the erosion is active, look at the gully head, walls and floor.

While the tillage does fill in the gully, each time the gully washes out again, the soil is lost from the gully and from along the sides of the gully as that soil was used to repair the gully. Rather than repairing the gullies every year, use terraces to intercept the runoff and grass waterways or underground tile lines to carry the runoff from the field without causing more erosion.

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 ...
