摘要

这项评估研究的重点是阿尔及利亚南部 Wadi Righ 地区的水化学特征和地下水适宜性。问题的陈述围绕使用各种指数确定水质,包括渗透指数 (PI)、残留碳酸钠 (RSC)、水质指数 (WQI)、钠百分比 (Na%)、钠吸附率 (SAR)、加拿大环境部长理事会水质指数 (CCMEWQI)、镁危害 (MH)、灌溉水水质指数 (IWQI) 和凯利指数 (KR)。此外,还利用统计方法建立了这些指数与化学元素之间的相关性。工作方法包括调查 Wadi Righ 地下水的水化学参数和分析 52 个样本。从数量上看,结果表明,根据水质指数评估,水质总体上被归类为极差和不适宜,尤其是在中部和南部地区观察到的水质较差。不过,地下水的水质很好,适合灌溉。定性分析结果表明,正如皮尔逊相关分析所显示的,灌溉适宜性指数之间存在显著的关 系。这些关系源于地下水的共同输入和水文地质化学特征。这一定性分析加强了定量分析结果,并使人们深入了解了影响瓦迪里格地区地下水质量和灌溉适宜性的根本因素。

Appraisal of groundwater suitability and hydrochemical characteristics by using various water quality indices and statistical analyses in the Wadi Righ area, Algeria
This assessment research focuses on the hydrochemical characteristics and groundwater suitability in the Wadi Righ region, in southern Algeria. The statement of the problem revolves around determining water quality using various indices including Permeability Index (PI), Residual Sodium Carbonate (RSC),Water Quality Index (WQI),Sodium Percentage (Na%), Sodium Adsorption Ratio (SAR), Canadian Council of Ministers of the Environment's Water Quality Index (CCME WQI), Magnesium Hazard (MH), Irrigation Water Quality Index (IWQI), and Kelly Index (KR). Additionally, statistical methods were utilized to establish correlations between these indices and chemical elements. The working method involved investigating hydrochemical parameters in Wadi Righ's groundwater and analyzing 52 samples. Quantitatively, the results indicate that water quality, as assessed by the water quality indices, was categorized as very poor and unsuitable overall, with lower quality observed particularly in the central and southern regions. However, groundwater demonstrated excellence and suitability for irrigation purposes. Qualitatively, the findings suggest that there are significant relationships among irrigation suitability indices, as indicated by Pearson correlation analysis. These relationships stem from shared inputs and hydrogeochemical characteristics of groundwater. This qualitative analysis reinforces the quantitative findings and provides insights into the underlying factors influencing groundwater quality and suitability for irrigation in the Wadi Righ region.
