Assesement of the Spatial Variation of River Tigris Chemistry in Iraq by Discriminant Analysis

Sawsan M. Ali

Abstract :

Multivariate cluster analysis and discriminant analysis were applied to investigate and assess the spatial variations of some hydrochemical parameters along eight stations on the River Tigris in Iraq. These parameters are:pH,TDS,TH,Ca,Mg,Na,K,SO4,HCO3,Cl, NO3, COD and DOB. They are used as an independent variables in the application of the discriminant analysis. Cluster analysis results show presence of three distinct groups of similar water quality parameters behavior. Application of the stepwise selection of the spatial discriminant analysis explained that pH, TDS, EC, TH and Ca are the most discriminating variables among the previously identified groups. Discriminant analysis shows that 100% and 76% of the original data and cross-validated groups data were correctly classified. These results confirm that there no significant effects of anthropogenic factors along all the selected stations could be detected , where the hydrologic and geologic factors can be regarded as the main responsible factors controlling the River Tigris water chemistry in Iraq
