Introduction and Background: Gully erosion is one of the most advanced kind of water erosion that carries a lot of sediment and causes various environmental challenges. Therefore, identifying and investigating of effective factors is necessary on forming and promoting of erosion in study area.
Aims: The aim of this study is to evaluate the factors influencing on dynamic of area Gullies in a one year time period.
Methodology: In this study, electrical conductivity, sodium absorption ratio, PH, soil type and WS index has been used for analyzing of gully erosion potential.
Conclusion: Results indicate that according to WS index the study basin has much potential for gully erosion as of gullies morphometry indicates much speed of promotion of gullies, laboratory results of sample soils of soluble minerals, SAR, electrical conductivity, the amount of sodium in soil are effective on piping erosion are the most important effective factors on formation and promotion of gully erosion and morphometric characteristics of gullies. It is thought from the results of study that physical and chemical conditions of soil and rainfall have been effective on soil erosion and gullies development from length and width
