تحليل آماري نتايج تجزيه شيميايي آب زيرزميني دشت عباس

Statistical analysis of chemical analysis results of Abbas plaints groundwater

Abbas plain is located in the north-west part of Khuzestan and also south-east of Ham state , between 47° 40-48° 05E and 32° 15- 32° 35N. The groundwater in this plain is significantly turned into a saline water .The statistical analysis of the numbers derived from the water samples experiments , indicates that southern area in comparison with middle and northern part, has high values of EC (Electrical Conductivity) and TDI (Total Dissolved Ions) .Also the EC of the samples has been effected mainly by the Calcium. In wet-season , concentration of dissolved ions in water increase, while they decrease in dry-season. This may be because of the intrusion of rain water into the aquifer and solution of salt that content in formation in the wet-season and decrease precipitation that is caused decrease of salt solution in dry-season.
