We present the results of the geophysical valuation of aquifer protectivity, groundwater potentiality and flow properties in the northern part of Akwa Ibom state, Nigeria. Vertical electrical sounding (VES) and electrical resistivity tomography (ERT) were conducted at 55 and 20 locations respectively in the study area to generate 1D and 2D resistivity sections of the subsurface. A maximum of four layers have been delineated from the results of the electrical resistivity soundings. These layers are successions of poorly–sorted sands and gravels with minor clay intercalation at some locations. The aquifers lie between 1.0 to 47.8 m deep and are 18.6 to 102.7 m thick. The aquifer protective capacity (APC) grading is adjudged to be poor (96 %) to weak (4 %) respectively as the overlying layers are mostly porous and permeable. However, the aquifers have great groundwater potential with 6 % moderate grading, 9 % high grading and 85 % very high grading. The discrete rock typing (DRT) results delineate the aquifers into two hydraulic flow units (HFU) of sandy clay and fine/coarse/gravelly sands. The stratigraphic modified Lorenz Plot (SMLP) technique however delineates the aquifers into five HFUs, classified as conductors (96 %) and super conductors (4 %) with ranking efficiencies of fair and good respectively. The DRT and SMLP classifications seem to show consistency, which indicate the fidelity of our investigation approach. The aquifer units are shown to be highly heterogeneous, corroborated by the electrical resistivity sounding results and the variability in the HFUs inferred from the SMLP results. The established regression equations in this research could be utilized for the predictions of aquifer hydraulic and flow properties from surficial electrical sounding data in locations with comparable geology. These results are highly propitious in the development of efficient strategies to preserve groundwater resources in the area by policymakers and water resource managers.</div></div>","PeriodicalId":100582,"journal":{"name":"Geosystems and Geoenvironment","volume":"4 3","pages":"Article 100401"},"PeriodicalIF":0.0,"publicationDate":"2025-04-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143932091","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The process of volcano generation and the characteristics of Java Island as part of the Sunda Arc produce Quarternary volcanoes from the western to the eastern land. Remote sensing provides an opportunity to characterize volcanoes all over Java Island by analyzing the occurrences of their volcanic products. In this study, we have characterized spatially of the volcanoes expressed by volcano density or sum of volcanoes per area (i.e., 0.5° × 0.5° or 3098.04 km²). The Landsat 8 and 9 OLI data were processed and displayed in False Color Composite (FCC) R, G, B for Band 5, 6, 7 to identify volcanic products distribution. The True Color Composite (TCC) R, G, B for Band 4, 3, 2 was also used to identify vegetation cover affected by volcanic products. The FCC assisted by TCC images were used visually to determine the boundaries of the volcanic products area, calculate their coverage area, determine the main flow directions, and maximum length. The calculated volcano density map shows that the Java Quaternary volcanoes were divided into three segments. The western segment is the highest density about five volcanoes, the central segment varies between one and three volcanoes, and the eastern segment is about two volcanoes per area. The volcanic products were successfully identified by seventeen out from twenty volcanoes. The large area of volcanic products such as Mt. Guntur (12,287,138 m²), Mt. Merapi (18,258,542 m²), and Mt. Semeru (18,645,778.3 m²) are associated with explosive eruption.

Cu significantly contaminated most water samples, according to the enrichment factor (<em>EF</em>), contamination factor (<em>CF</em>), pollution load index (<em>PLI</em>), and potential ecological risk (<em>PER</em>). As Cr influenced the heavy metal evaluation index (<em>HEI</em>) and heavy metal pollution index (<em>HPI</em>), Tanguar Haor water is severely contaminated. The hazard index (<em>HI</em>) and particular hazard quotients (<em>HQ</em>s) for adults and children demonstrated no non-carcinogenic heavy metal risk from cutaneous exposure. In addition, every station discovered that the values of Cr and Pb were much beyond the permitted limit given by the Bureau of Indian Standards (BIS), the Environment Conservation Rules (ECR), and the World Health Organization (WHO). Both adults and children have significant Cr's carcinogenic risk. However, adults are more vulnerable to both carcinogenic and non-carcinogenic risks. Thus, S12, near Barek Tila station, is severely toxic and dangerous. Pearson correlation showed a substantial positive correlation between Cu-Mn, Ni-Cu, Cu-Pb, and Cr-Ni, suggesting the same origins, whereas Zn and Mn were uncorrelated, showing separate origins. Primary metal contamination in Tanguar Haor, Bangladesh, comes from agricultural, household, and industrial wastes directly dumped into the waterways. Excessive metal contamination may affect local water quality, fish, food, livelihoods, and public health.

However, it is often overlooked despite accounting for over one-third of global freshwater supplies. Geophysics plays a critical role in exploring, developing, and sustaining groundwater resources.

It also examines the transformative power of geophysical techniques, highlighting their effectiveness in mapping aquifer properties such as thickness, depth, volume, hydraulic conductivity, flow pathway, faults, and fractures to monitor groundwater levels and assess aquifer potential and vulnerability. Case studies demonstrate the efficacy of geophysical methods in groundwater studies across the globe. For instance, electrical resistivity (ER) surveys have been employed to identify promising aquifer zones with relative resistivity values ranging from 10 Ωm to 500 Ωm and transmissivity values ranging from 0.79 to 1203 m²/day, occurring with depths of <span><math><mrow><mo>≥</mo><mn>5</mn><mspace></mspace><mi>m</mi></mrow></math></span>.

The limitations and strengths of geophysical methods were also discussed alongside the other methods, such as geological observation, hydrogeological survey, test drilling, remote sensing (RS), and tracing its evolution from the era of blind exploration. While challenges exist, the future of groundwater management hinges on the continued development and application of geophysical methods. By integrating these techniques with the insights from hydrogeological and other methods, we can optimize well-siting, enhance aquifer recharge, and ensure long-term sustainable groundwater resource management (GWRM).

The analysis revealed that PC1 captured the highest accuracy for lineament extraction. Sentinel-1 SAR data, acquired in Interferometric Wide (IW) swath mode with dual polarization (VV and VH), was processed using Google Earth Engine, allowing for detailed analysis of surface features. The VH polarization was particularly effective in detecting fine-scale linear features due to its sensitivity to surface roughness and vegetation penetration.

Stereographic projections were utilized to analyse and visualize structural orientations, including schistosity, lineations, shear foliations and fold axes, providing insights into the area's tectonic evolution. The comparative analysis of lineament characteristics from Landsat-9 OLI and Sentinel-1 SAR datasets indicated that while Sentinel-1 detected a greater number of shorter lineaments, Landsat-9 provided longer lineaments with distinct orientations.
