Gully erosion is one of the most destructive types of hydraulic erosion and an important process insoil destruction that in some cases creates long, vast, deep canals. Study area was located in thenortheastern Alborz, Mazandaran province and Nowshar County (Firozkola subbasin a portion ofKojur watershed). This paper examines gully morphometery in relation with physical and chemicalcharacteristics of soil. The morphometery of gullies such as width, depth and slope were determinedin field. Physical and chemical properties of soil such as exchange cation (EC), organic andinorganic carbon, soil acidity and soil texture were determined in the laboratory. Data analyses wereperformed by Detrended correspondence analysis (DCA). The DCA analysis indicated that thewidth and slope are correlated with OC and clay negatively but they have positive correlation withpH. Hence, it's expected that following reduction of OC and clay and an increase in PH, gully widthboosts. Besides, if EC increases and CaCO3 decreases, depth and w/d ratio of gully will increase.
