Abstract

Groundwater resources are increasingly strained by misuse and climate change, necessitating the identification of potential recharge zones for sustainable management. The study aimed to simulate potential recharge zones of a tropical river basin using two multi-criteria decision-making techniques: the Analytical Hierarchy Process (AHP) and Multi-Influencing Factor (MIF) methods. Thematic layers of key variables were integrated using a weighted overlay analysis in GIS environment to model recharge areas within a tropical river basin in Northern Kerala, India. Normalized weights and ranks were calculated to evaluate their influence on groundwater development. Five classes of groundwater recharge potential zones (GWRPZ) with their derived areas were identified for AHP and MIF, respectively: high (30.39% and 28.24%), low (21.55% and 21.60%), very high (19.20% and 18.45%), moderate (16.96% and 20.25%), and very low (11.90% and 11.45%). Validation with overall accuracy and Kappa coefficient confirmed the methods' comparability. The results guide water well site selection and improve managed aquifer recharge (MAR) strategies. Local bodies within the river basin were ranked utilizing the Technique for Order of Preference by Similarity to Ideal Solution (TOPSIS) method to prioritize and implement recharge schemes, aiding sustainability goals in groundwater management.

印度喀拉拉邦北部河流流域地下水补给潜力区的多准则决策方法比较分析

地下水资源因滥用和气候变化而日益紧张，因此有必要确定潜在的补给区进行可持续管理。采用层次分析法（AHP）和多影响因子法（MIF）两种多准则决策方法模拟了热带河流流域的潜在补给带。利用GIS环境下的加权叠加分析，对关键变量的主题层进行了整合，以模拟印度喀拉拉邦北部热带河流流域的补给区。计算归一化权重和等级，评价其对地下水发育的影响。AHP和MIF分别划分为高（30.39%和28.24%）、低（21.55%和21.60%）、极高（19.20%和18.45%）、中等（16.96%和20.25%）和极低（11.90%和11.45%）5类及其衍生面积。总体准确度和Kappa系数验证了方法的可比性。研究结果可指导井位选择和改进含水层管理补给（MAR）策略。利用理想解决方案相似性偏好排序技术（TOPSIS）对流域内的地方机构进行排序，以优先考虑和实施补给方案，有助于实现地下水管理的可持续性目标。
