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).Land degradation and gully development in arid environments deduced by mezzo- and micro-scale 3-D quantification - The Negev Highlands as a case study ...
