This study integrates Vertical Electrical Sounding (VES), Geographic Information Systems (GIS), Remote Sensing (RS), and the Analytic Hierarchy Process (AHP) to evaluate groundwater potential and aquifer vulnerability in the study area. Ten VES stations were investigated using the Schlumberger electrode configuration with current electrode spacing ranging from 2 to 200 m. The interpreted geoelectrical parameters were used to estimate aquifer hydraulic properties, including hydraulic conductivity, transmissivity, longitudinal conductance, transverse resistance, porosity, and permeability. Four groundwater conditioning factors, rainfall, geology, lineament density, and soil type, were integrated within a GIS environment using AHP to generate the Groundwater Potential Index (GWPI). The AHP weighting identified rainfall (55.8%) as the dominant groundwater conditioning factor, followed by geology (26.3%), lineament density (12.2%), and soil type (5.7%), with a consistency ratio of 0.045, indicating reliable pairwise judgments. Hydraulic conductivity ranged from 0.0839 to 28.7584 m\u002Fday, transmissivity from 6.1 to 853.1 m²\u002Fday, porosity from 0.1764 to 0.6870, and permeability from 100.32 to 34,380 mD, demonstrating considerable spatial heterogeneity in aquifer properties. The GWPI map classified the study area into Very Low, Low, Moderate, High, and Very High groundwater potential zones, with the western, northwestern, and central sectors exhibiting the most favourable groundwater conditions. Validation against VES-derived transmissivity showed 100% agreement, comprising 50% excellent and 50% good correspondence between the GIS-AHP predictions and geoelectrical interpretations. The integrated approach provides a reliable framework for groundwater exploration, borehole siting, aquifer protection, and sustainable groundwater resources management in rapidly urbanizing coastal environments.","地下水是尼日利亚河流州哈科特港的主要饮用水来源，其原因在于快速城市化、工业化和人口增长导致地表水资源日益退化。本研究综合运用垂向电测深（VES）、地理信息系统（GIS）、遥感（RS）和层次分析法（AHP），对研究区地下水潜力和含水层脆弱性进行评价。采用施伦贝格尔电极装置，在10个VES测点开展探测，供电电极距为2至200 m。利用解译的地电参数估算含水层水力特性，包括渗透系数、导水系数、纵向电导、横向电阻、孔隙度和渗透率。将降雨、地质、线性构造密度和土壤类型四个地下水控制因子在GIS环境中通过AHP进行集成，生成地下水潜力指数（GWPI）。AHP权重分析表明，降雨（55.8%）为主导地下水控制因子，其次为地质（26.3%）、线性构造密度（12.2%）和土壤类型（5.7%），一致性比率为0.045，表明两两判断可靠。渗透系数为0.0839至28.7584 m\u002Fd，导水系数为6.1至853.1 m²\u002Fd，孔隙度为0.1764至0.6870，渗透率为100.32至34,380 mD，表明含水层特性具有显著空间非均质性。GWPI图将研究区划分为极低、低、中等、高和极高地下水潜力区，其中西部、西北部和中部的 地下水条件最为有利。以VES解译的导水系数进行验证，结果显示GIS-AHP预测与地电解译之间100%吻合，其中50%为极好对应，50%为良好对应。该综合方法为快速城市化海岸环境中的地下水勘探、井位选址、含水层保护和地下水资源可持续管理提供了可靠框架。",null,"Nigerian Journal of Physics","2026-09-11T00:00:00Z","论文",10,false,0,{"impact":15,"substance":15,"depth":15,"authority":15,"freshness":15,"relevant":15,"comment":17},"研究对象为尼日利亚哈科特港城市地下水潜力评估，与三农、农业信息化及中国数字乡村议题无直接关联，不建议进入每日精选。",[19],{"name":10,"url":6},[21,22,23],"遥感监测","地下水评估","GIS应用","10.62292\u002Fnjp.v35(s).2026.693",{"doi":24,"openalex_id":26,"authors":27,"venue":10,"cited_by_count":15,"oa_url":37,"card":38,"direction":42,"ingested_from":44},"W7212370737",[28,30,33,35],{"name":29,"orcid":9},"Sulyman Usamat",{"name":31,"orcid":32},"Godwin Babatunde Egbeyale","https:\u002F\u002Forcid.org\u002F0000-0003-4091-2381",{"name":34,"orcid":9},"Sunday Ajani Adegbenro",{"name":36,"orcid":9},"Salami A.
