The Study of Selected Chemical Properties and Statistical Analysis of Tigris River Water Samples in Wasit Province/Iraq

Abstract

   This research was conducted and aimed to study selected chemical properties of water samples taken from Tigris river in selected areas from the province of Wasit .The areas are regions of Suwiara and Numaniyah districts. Water chemical analyses were conducted and analyzed in the chemical laboratories of  environment directorate in Wasit province. Data were statistically treated using Data fit software package. Simulations and models were built depending on the values of SAR, Ec, and  pH. The results showed an existence of high significant statistical relationships between (SAR, EC, and pH) , (SAR and  EC) and (EC ,and pH) were found as represented in the high values of the coefficient of determination( R²) for WQMsS2 and WQMsN2. Also, results showed that, the best  statistical relationship was between (SAR and  EC,) for both locations
