Abstract

The aim of this study is to explore the primary factors influencing water quality in Wadi Guebli (Northeastern Algeria) and evaluate its suitability for irrigation by employing a combination of hydrochemical examination and multivariate statistical methods. Throughout the year 2023, water samples were collected from seven sampling locations and analysed for sulfate ⁽\({\text{SO}}_{4}^{{2 - }}\)), sodium (Na^+), potassium (K⁺), calcium (Ca²⁺), bicarbonate (\({\text{HCO}}_{3}^{ - }\)), chloride (Cl^–) and magnesium (Mg²⁺) ions. The hydrochemical properties of water samples were determined using the Piper diagram, with the K⁺-\({\text{HCO}}_{3}^{ - }\) water type being the dominant facies. Magnesium ratio (MR), Kelly index (KI), sodium absorption ratio (SAR), sodium percentage (Na⁺%), residual sodium carbonate (RSC) and permeability index (PI) values were employed to assess the suitability of the water for irrigation purposes. Calculated values of these parameters show that the Wadi Guebli waters present a danger for irrigation.

瓦迪格布利（阿尔及利亚东北部）水的水化学特征和灌溉适宜性

摘要本研究旨在探讨影响 Wadi Guebli（阿尔及利亚东北部）水质的主要因素，并通过结合使用水化学检查和多元统计方法评估其灌溉适宜性。2023 年全年，从七个采样点采集了水样，并分析了硫酸盐 (\({text{SO}}_{4}^{2 - }}\)) 、钠 (Na+)、钾 (K+)、钙 (Ca2+)、重碳酸盐 (\({text{HCO}}_{3}^{ - }\)) 、氯化物 (Cl-) 和镁 (Mg2+) 离子。水样的水化学性质是通过皮珀图（Piper diagram）确定的，K+-\({text{HCO}}_{3}^{ - }\) 水类型是主要的类型。采用镁比率（MR）、凯利指数（KI）、钠吸收比率（SAR）、钠百分比（Na+%）、残留碳酸钠（RSC）和渗透指数（PI）值来评估水是否适合灌溉。这些参数的计算值表明，瓦迪格布利水域存在灌溉危险。
