Abstract

Groundwater resource management is a critical component of sustainable water use, necessitating accurate and nuanced mapping of groundwater potential zones. This study analyzed the groundwater potential of Algeria's 43,750 km² Chelif Basin (more than 17% of the area of Northern Algeria) using a combination of both subjective and objective mapping techniques. The adopted approaches encompass the benchmark analytical Fuzzy Analytic Hierarchy Process (Fuzzy-AHP) and the DEcision MAking Trial and Evaluation Laboratory (DEMATEL) methodologies to quantify interdependencies of criteria related to groundwater potential. The analysis focused on ten criteria related to groundwater potential, including core moisture availability and key hydrological factors like distance to river, topographic wetness index, and hydrological soils. Fuzzy-AHP achieved slightly higher groundwater prospecting accuracy (AUC = 0.730) than classic AHP (0.716), with benchmarking against 15 related studies indicating robust performance. Instead of the most commonly used criteria in groundwater literature such as lineament, stream order, recharge rate, and drainage density, this study employed alternative factors to challenge and validate the efficacy of the proposed methodology. The decision to omit certain criteria facilitated a more focused and manageable analysis, yet still delivered a robust evaluation of groundwater potential in the studied area. Moreover, this approach underscores the adaptability of the proposed methodology to accommodate varying sets of criteria, tailored according to the availability of data and specific research objectives. Additionally, the DEMATEL evaluation reveals new insights into subtle prioritization divergences, specifically between domain specialist opinions and analytical assessments of the criteria. The integration of fuzzy logic and causal relationship mapping through DEMATEL provides a comprehensive and robust foundation for groundwater potential modeling.

利用混合分析方法加强地下水潜势区绘图：半干旱盆地案例

地下水资源管理是水资源可持续利用的重要组成部分，需要对地下水潜能区进行精确细致的测绘。本研究采用主观和客观绘图技术相结合的方法，分析了阿尔及利亚 43750 平方公里 Chelif 盆地（占阿尔及利亚北部面积的 17%以上）的地下水潜力。所采用的方法包括基准分析法模糊层次分析法（Fuzzy-AHP）和决策制定试验和评估实验室（DEMATEL）方法，以量化与地下水潜力有关的标准之间的相互依存关系。分析侧重于与地下水潜力相关的十项标准，包括核心水分可用性和关键水文因素，如与河流的距离、地形湿润指数和水文土壤。与传统的 AHP（0.716）相比，模糊-AHP 的地下水勘探准确率（AUC = 0.730）略高，与 15 项相关研究进行的基准比较表明模糊-AHP 的性能稳健。本研究没有采用地下水文献中最常用的标准，如线型、溪流顺序、补给率和排水密度，而是采用了其他因素来挑战和验证所建议方法的有效性。省略某些标准的决定有助于进行更集中、更易于管理的分析，但仍能对研究区域的地下水潜力进行有力的评估。此外，这种方法强调了建议方法的适应性，可根据可用数据和具体研究目标来调整不同的标准集。此外，DEMATEL 评估还揭示了在确定优先次序方面的微妙分歧，特别是领域专家意见与标准分析评估之间的分歧。通过 DEMATEL 对模糊逻辑和因果关系图进行整合，为地下水潜势建模提供了一个全面而稳健的基础。

期刊介绍： Groundwater for Sustainable Development is directed to different stakeholders and professionals, including government and non-governmental organizations, international funding agencies, universities, public water institutions, public health and other public/private sector professionals, and other relevant institutions. It is aimed at professionals, academics and students in the fields of disciplines such as: groundwater and its connection to surface hydrology and environment, soil sciences, engineering, ecology, microbiology, atmospheric sciences, analytical chemistry, hydro-engineering, water technology, environmental ethics, economics, public health, policy, as well as social sciences, legal disciplines, or any other area connected with water issues. The objectives of this journal are to facilitate: • The improvement of effective and sustainable management of water resources across the globe. • The improvement of human access to groundwater resources in adequate quantity and good quality. • The meeting of the increasing demand for drinking and irrigation water needed for food security to contribute to a social and economically sound human development. • The creation of a global inter- and multidisciplinary platform and forum to improve our understanding of groundwater resources and to advocate their effective and sustainable management and protection against contamination. • Interdisciplinary information exchange and to stimulate scientific research in the fields of groundwater related sciences and social and health sciences required to achieve the United Nations Millennium Development Goals for sustainable development.
