Abstract

The study focuses on the characterization of the groundwater salinity on the Nador coastal aquifer (Algeria). The groundwater quality has undergone serious deterioration due to overexploitation. Groundwater samplings were carried out in high and low waters in 2013, in order to study the evolution of groundwater hydrochemistry from the recharge to the coastal area. Different kinds of statistical analysis were made in order to identify the main hydrogeochemical processes occurring in the aquifer and to discriminate between different groups of groundwater. These statistical methods provide a better understanding of the aquifer hydrochem-istry, and put in evidence a hydrochemical classification of wells, showing that the area with higher salinity is located close to the coast, in the first two kilometers, where the salinity gradually increases as one approaches the seaside and suggests the groundwater salinization by sea-water intrusion.
多元统计技术在阿尔及利亚蒂帕扎纳多尔沿海含水层地下水水质表征中的应用
研究的重点是纳多尔沿海含水层(阿尔及利亚)地下水盐度的特征。由于过度开采,地下水水质严重恶化。为了研究从补给区到滨海区地下水水化学的演变,2013年在高、低水位进行了地下水采样。为了识别含水层中发生的主要水文地球化学过程,并区分不同类型的地下水,进行了各种统计分析。这些统计方法提供了对含水层水化学的更好理解,并证明了井的水化学分类,表明盐度较高的区域位于靠近海岸的地方,在前两公里,随着靠近海边,盐度逐渐增加,表明地下水因海水入侵而盐渍化。
