Abstract :
This study investigates the quality of the Orontes River by conducting a statistical analysis at certain monitoring points.as 11 monitoring points were distributed along the river from the point of its entry into the Governorate of Homs until its exit from it, and for this purpose, methods of multivariate statistical analysis were applied (cluster analysis, Factor analysis). By using the statistical program /SPSS/ to find out the advantages of the variables, the results indicated the possibility of reducing the number of measured variables and reducing the number of monitoring points along the stream, as the cluster analysis showed the presence of two clusters (low pollution, polluted), which could reduce the number of sampling sites according to similar specifications. By applying the factor analysis to study the changes to compare the compositional patterns between clusters, It gave /4/ basic factors with the degree of measurement quality of 85.7% > 50%, and the best rate for explaining the total variance ratios is 87.86% of the total variance and includes (7) basic variables: (EC, Na, BOD, COD, NO3, DO, TSS).
