Abstract: 

Occurrence of gully erosion on an area causes major impacts. Large area of the Sorkh-abad watershed in the Savadkooh district dissected by gullies. In this research several effective environmental factors on gully volume growth of 14 gullies have been evaluated in two six-month intervals (1year). At first rule of some gully's morphometric characteristics on volume growth have been estimated, then effects of environmental variables on gully volume growth have been calculated by multivariate regression analysis. The results of this research demonstrated that gully volume growth has been increased with increasing of gully length and height of headcut at all cases. Also according to introduced equations of multivariate regression analysis in this study, has been illustrated variables such as precipitation over 10mm per 24h, area of gully drainage basin, soluble salts and clay in soil have more effective rules on gully volume growth.
