“…Among several models, Erosion Potential Method -EPM, originally developed for Yugoslavia by Gavrilovic (1972), was repeatedly applied in Iran (Draganic et al, 2015;Leandro Naves Silva et al, 2015;Behzadfar et al, 2015Behzadfar et al, , 2014aBehzadfar et al, , 2014bMoradi et al, 2015;Amini et al, 2014;Zia Abadi and Ahmadi, 2011;Sadeghi, 2005Sadeghi, , 1993Khaleghi, 2005;Maleki, 2003;Nadjafi, 2003) the watersheds of Apennine and in the Balkan Peninsula (Blinkov and Kostadinov, 2010;Kostadinov et al, 2014Kostadinov et al, , 2006Lenaerts, 2014;Milevski et al, 2008;Ristic et al, 2012;Sekularac, 2013;Spalevic et al 2014aSpalevic et al , 2014bSpalevic et al , 2013aSpalevic et al , 2013bSpalevic et al , 2013cSpalevic et al , 2012aSpalevic et al , 2012bStefanovic, 2004;Tazioli, 2009, Zorn andKomac, 2008), but also in the other regions in the world, for example in arid and semi-arid areas of the south-western USA (Gavrilovic, 1988), Saudi Arabia (Al-Turki et al, 2015;Aburas Al-Ghamdi, 2010)... The method is based on the factors affecting erosion in a catchment; its parameters dependent on the temperature, the mean annual rainfall, the soil use, the geological properties and some other features of the catchment.…”
