摘要: Abstract Groundwater contamination is a significant problem related strongly to both the protection of environment and need for water. In present study, groundwater quality was investigated in Bojnourd watershed. The watershed located northeast Iran, which covers 65.5 km2 North Khorasan province area. There are 11 extracting wells region. Annual water extraction from alluvial aquifer area used agriculture, drinking, sanitary industrial consumptions. this research, quantity modeling, including calibration verification by GMS software, had been performed. modeling stage, pollution contours Electrical conductivity were mapped analyzed MT3DMS. spread salinity pollutants predicted 15 years MT3DMS, 3D modular software advection, dispersion, molecular diffusion, chemical reaction, solute absorption simulation. purpose research simulate electrical (EC) on catchment predict future trends EC changes with MT3DMS software. Therefore, we generated two different scenarios model. Assuming current situations simulating TDS, as first scenario, implementing municipal sewage systems whole city, second years. results showed that discharge solid waste landfill site domestic wastewater would severely affect while system will improve significantly period
