    We used statistical analysis to try to evaluate the temporal variations concerning surface water located in Baber watershed. So, we collected twenty-one samples, for each city, seven ones were collected. In these samples, we determined eleven physicochemical parameters concerning the eastern part (S1): The salinity of samples proves high TDs values, while low TDs levels were found in the west (S2). In the dam (S3) TDs values are considered as intermediate on average. Regarding the water type: It wasSO4-Na in S1, HCO3-Ca-Mg in S2 and finally SO4-Ca- Mgin the dam (S3) which characterizes mixed water. In R-mode, Cluster analysis was used; we classified seven variables into two clusters which are controlled by SO4. About Q-mode, 21 samples were grouped into three groups corresponding to our three stations: S1, S2 and S3. Factor analysis is indic.. View more»
