Methods: Sampling in winter and summer season In two turns and three replications from7stations including Taleghan, Alamut, Rajai Dashte, Razmian, Loshan,Lowshan1andLoshan2hasbeenusedandthequalitativeparametersinclude:TDS,pH,sodium,DO,temperature,chloride,sulfate,calcium,Mg,Bicarbonate, hardness based on calcium carbonate, Cu, Cr,Zn and obtained data using Shooler indexes, Wilcox and the water quality test were determined for each section of the grocer. Results: for agricultural purposes according to the Wilcox index in The range of usable and for drinking using Shooler's score is reasonable and also for industrial use according to According to the results of this study, the waters of the Shahrood River are based on Different parameters in Schuler's index showed that in terms of a very good and acceptable water standard that is suitable for drinking and In terms of health, the quality is appropriate. According to Wilcox results, all stations studied in two-part intervals are limited alittle salty to salty that is suitable for use in agriculture and also based on the method of piper method and river water in two seasons,Ca-Na-HCO3 is bicarbonate and industrial use,16% of the samples are balanced,33%in the sediment group and44%in the corrosive group.
