对Koudiat Medouar流域的地表水进行评估是非常重要的，特别是当涉及到Oued Timgad邻近城镇排放的废水污染大坝水域时，这些废水涌入大坝流域，以及沿着Oued Reboa的农业用地。为此，采用多变量法对阿尔及利亚东部Koudiat Medouar大坝的水面水质时空变化进行了评价。刚性图确定了两种主要的水化学相。第一相Mg-HCO3反映在第一个采样点（Oued Reboa）和第二个采样点（Oued Timgad），第二相Mg-SO4反映在第三个采样点（Basin Dam）。方差分析结果表明，除第1站（Reboa）的Na、K和HCO3、第2站（Timgad）的EC、末3站（Basin Dam）的NO3和pH外，3个站点的其他参数均显著。q型层次聚类分析表明，每个采样站存在两个主要群体。3个台站内主要离子（Mg、Ca、HCO3和SO4）的化学性质受人为影响和水岩相互作用源的影响。
The assessment of surface water in Koudiat Medouar watershed is very important especially when it comes to pollution of the dam waters by discharges of wastewater from neighboring towns in Oued Timgad, who poured into the basin of the dam, and agricultural lands located along the Oued Reboa. To this end, the multivariable method was used to evaluate the spatial and temporal variation of the water surface quality of the Koudiat Medouar dam, eastern Algeria. The stiff diagram has identified two main hydrochemical facies. The first facies Mg-HCO3 is reflected in the first sampling station (Oued Reboa) and in the second one (Oued Timgad), while the second facies Mg-SO4 is reflected in the third station (Basin Dam). The results obtained by the analysis of variance show that in the three stations all parameters are significant, except for Na, K and HCO3 in the first station (Oued Reboa) and the EC in the second station (Oued Timgad) and at the end NO3 and pH in the third station (Basin Dam). Q-mode hierarchical cluster analysis showed that two main groups in each sampling station. The chemistry of major ions (Mg, Ca, HCO3 and SO4) within the three stations results from anthropogenic impacts and water–rock interaction sources.
