Investigating the Effect of Diapers on Salinization of Water and Soil Resources Case : Shoor Drainage Basin, Kakan, Yasuj

Salt hills in Zagros Mountains are one of the most important areas that have Diaper phenomenon in Iran and the world. Kakan region is of  Hormuz diaper series that have devastating effects on water and soil quality and from the view point of natural resources has not been introduced. Therefore, in order to determine the obvious impact of diapers on water and soil resources, water and soil sampling was made. The sampling of water samples were taken during different times and places, and randomly. So that density of the samples was more in the adjacent of diaper. Also in each sampling point, water flow rate was measured. Analysis results and the chemical properties of soil and water samples showed that although the studied diapers are not extensive  and  a small part  of the river passes through it, but it is the only factor for Stalinization of the water of Shor river , and according to hydrological and hydro geological conditions, its  effects  can be different. In fact, the diapers studied in this area were active that depending on the weather conditions can have severe damages in the area. Also results of statistical analysis showed a significant difference between water quality characteristics of the river before and after the rainfall. Also the results of correlation matrix showed a significant relationship between water quality characteristics with the flow rate  after the rainfall and no significant difference was observed before the rainfall . Due to the small  effective area on water quality and its soil degradation, it can be said that by controlling the  water of saline springs and also by creating plant  coverages  in waterways in the diapered area, the amount of water and soil degradation in this region and in the downstream regions will decrease.
