Investigating the Effect of Groundwater on Aquifer Water Salinity Change (Case Study: Neyshabour plain)

Nowadays, one of the main problems of water resources in the country is the decline of water resources quality. The increasing demand for water has led to untapped groundwater exploitation and constant water loss in aquifers and as a result environmental problems including the quality of groundwater have been endangered and have created a destructive process. In this study,using the collected data from Neyshabour plain , relationship between groundwater level and increase salinity was determined. In order to investigate the quantity and quality of groundwater in the Neyshabour plain, using the data of surface water level and electrical conductivity, the map of changes in the water level and the qualitative variables were determined in the ArcGIS 10.2 software using a Geostatistics method. The results of the spatial zonation mapping of the quantity and quality of groundwater in wells showed that the water level decreased with the passage of time in the specified period and consequently its amount quality decreased.
