Gully in arid climate.

Gully erosion, which is a destructive form of soil erosion in arid and semiarid regions (Arabameri et al., 2018d), threatens land sustainability. This phenomenon is due to the high erosion rates triggered by gullies, and it results in damage to agricultural land, infrastructure and urban areas.Download this page – Gully erosion (WORD - 111.7 KB) Gully erosion is the removal of soil along drainage lines by surface water runoff.

Water scarcity concerns the quantity and the quality of the resource available, because degraded water resources are considered unusable for more stringent water uses.1. Introduction. Gully erosion causes in-site and downstream environmental degradation. Human activities in arid and semi-arid areas accelerate gully occurrence that alters Earth's landscapes and affects human-environmental sustainability (Lesschen et al., 2007, Garosi et al., 2018).Usually gully erosion is known as anthropogenic alteration of landscapes, resulting in a serious threat to ...

It is termed the three-section method (TSM). It includes eight different types of gullies with different ...

In spite of many research efforts on gully erosion, there is an argument about causes of gully erosion among researchers. Causes of gully erosion can be classified into three categories: human impact (Bork et al., 2001, Starr, 1989), climate change (Gregory and Moore, 1931) and intrinsic changes (Schumm and Hadley, 1957).
