In this research, after distinguished of main and branches river in the plain, we took some water samples from river and relation between EC with river length was distinguished. Also, with use of water quality and statistical on hydrometry stations like; mamloo on Jajrood river, pol-e-siman on shemiran river, kahrizak on kan river, sharifabad on karaj-jajrood river, relation between EC and SAR months changes with Debbie were determined. Also Water quality of each station in each month from Vilkoks diagram was determined. With use of geological studies on plain, influence of geplogical formation on water quality was studied, and also salt weights that moved from station to the plain was studied. The results showed that from north to south water quality was degrading.
