Abstract

Seymareh Dam site is located in 40 km northwest of Darreh Shahr City and in Ilam Province. In this study, the origin of the downstream brines of Seymareh Dam with the results of chemical and using two computational methods of Schoeller's Index Base Exchange and weight ratio (Na/Cl)-Cl and two graphical methods of Hounslow and Sulin graph were studied. The results of these methods show a lot of conformity. In this study, part of the aquifer has been contaminated with oil brines, and the polluted water is drained through springs into the Seymareh River, which has reduced the quality of the river's water for agricultural purposes. Based on the equivalence maps of the Index Basic Exchange and the water type, a hydraulic connection has been established between the oil brines and the aquifer through the observation wells. Based on the interpretation of the results, the study area has been affected by the oil spills in the Seymareh Dam area, and the Gachsaran Formation in the area has also increased the salinity of water resources, including sulfate. Based on this, until 1396, the area of polluted aquifer was 1.8 km2. Examining the quality of irrigation water of Seymareh River in the period of 2011 to 2017 shows that since 2013, the quality of river water based on Wilcox classification is not suitable for irrigation. Based on the regression of SAR and EC diagrams with respect to time, it is predicted that in 1401 the quality of river water will reach C4-S4.
