Groundwater quality zoning of Bijar-Divandere plain in Kurdistan province in terms of sedimentation and corrosion using GIS

Due to population growth, increasing welfare, development of industries and agriculture along with climate change, groundwater resources are always changing in terms of quantity and quality. Therefore, it seems necessary to study the quantitative and qualitative changes of groundwater to manage. For this purpose, in the present study to study the groundwater quality changes in Bijar-Divandere plain, in terms of sedimentation and corrosion, using the information received in the years 2009 to 2018 and each year for the two months of June and October as water months and Water scarcity has been addressed using the Geographic Information System (GIS). Also, by evaluating various indicators to determine corrosion and sedimentation, valid indicators such as Langelier, Reisner and Pocorius for industrial use and sedimentation and corrosion analysis were studied in this study. The results of the mentioned indicators showed that the groundwater of the western areas of the plain is prone to corrosion and the eastern areas were prone to sedimentation and the Reisner index showed the water quality of part of the center of the plain was neutral. It was suggested to use aeration to remove iron and manganese, cathodic protection, priming, glazing and painting of the desired facilities in the western parts of Bijar-Divandere plain to prevent water corrosion. Also, for the central regions to the east of the plain with water deposition properties and adverse effects on agriculture, industry and health of the region, the use of sedimentation inhibitors such as the use of phosphate compounds and less harvesting of water resources was recommended.
