1. Introduction. Gullies represent an important form of land degradation on a global scale (Vanmaercke et al., 2016, Zegeye et al., 2017, Selkimäki and González-Olabarria, 2017).Vegetation can result in the reinforcement of steep gully sidewalls and the interception of sediment transport processes on gully beds (Dong et al., 2014).Consequently, vegetation restoration has been proposed as an ...Abstract. This study was aimed at assessing the causes of the gully erosion and its effects on the agricultural lands in the arid region of southeastern Iran. In this study, we have used geologic maps in scales of 1:50,000 and 1:250,000, aerial photographs on a scale of 1:20,000, field observation, and GPS (global positioning system).In arid and semi-arid climates, such as the Semnan province, Iran, gullies cause very extensive damage and are considered a major environmental problem [26,46]. Therefore, the identification of the causes of gully erosion development and its zoning for comprehensive management planning by executive agencies remain essential.
