Gully in arid climate.

A drier climate in the semi-arid zone is thus expected to foster rill and gully development (e.g., Valentin, 2004). Under cold conditions, global warming is expected to increase the frequency of freeze–thaw cycles exacerbating the risk of gullying as shown in southern Saskatchewan, Canada, ( Archibold et al., 2003 ) and in southern Norway ...Water is a precious resource in an arid climate.

Introduction. Gullies and gully erosion are major problems worldwide, particularly in arid and semi-arid environments where vegetation can be relatively scarce and therefore ineffective for protecting the soil surface from high-intensity rainfall and overland flow of water (Kompani-Zare et al., 2011; Sankey and Draut, 2014).This work used three state-of-the-art machine learning techniques to produce a multi-hazard (MHR) map illustrating areas susceptible to flooding, gully erosion, forest fires, and earthquakes in Kohgiluyeh and Boyer-Ahmad Province, Iran.
