Statistical Multivariate Analysis Assessment of Dams’ Water Quality in the North-Central Algeria

Abstract

The aim of this study is to evaluate the dam’s water quality of North-Central Algeria. The water quality data was monitored at twenty different dams, between January and December of 2017, using 9 water quality parameters and a multivariate analysis such as Cluster Analysis (CA). The CA allowed the formation of five clusters between the sampling sites, reflecting differences between the water quality at different locations. The Ghrib and Herraza Dams were characterized by a strong mineralization with a concentration of total solids of more than 1600 mg L−1, reflecting the geological nature of the watershed.
