Prediction models of various pollutants in the river Tigris at Baghdad

Abstract

The variation of pollutant concentrations in surface waters shares broad interest by scientists and researchers in the field of water pollution control. Models are useful in defining the nature of water systems and the relation among its components. The degree of pollution, source of pollution and pollutant variation are among these components. This study evalutes the variations of various pollutants in the River Tigris at Baghdad utilizing different regression models. Some of the models used, give on excellent estimate of pollutants variation in term of distance, flow rate, and reference point concentration. Comparisons between estimated and actual values of pollutants are also mode.
