“…It is however essential to understand the stratigraphic structures of a terrain before its groundwater resource can be optimally harnessed, either through dug wells or boreholes (Olasehinde, 2010). Various methods have been employed in groundwater exploration globally, ranging from traditional methods such as fracture trace method and borehole drilling (Lattman and Parizek, 1964;Acharya et al, 2012) to the use of geophysical methods such as electrical resistivity, magnetics, electromagnetics, seismic, radiometric techniques and so on (McNeill, 1991;Bernard and Legchenko, 2003;Goldman and Neubauer, 1994;Hewaidy et al, 2015;Shishaye and Abdi, 2016;Helaly, 2017;Muhammad and Khalid, 2017;Muthamilselvan et al, 2017;Poongothai and Sridhar, 2017;Umar et al, 2017;Gao et al, 2018). In addition, Sunmonu et al (2016), Adagunodo et al (2018) and Joel et al (2019a) had established that geophysical methods are capable to map the depth togroundwater table.…”

Groundwater has been successfully investigated on sedimentary and basement terrains using resistivity technique by number of researchers (Okereke et al, 1998;Nwankwoet al, 2004;Singh et al, 2006;Ariyo and Adeyemi, 2009;Al-Amoush, 2010;Nwankwo, 2011;Zarroca et al, 2011;Ikhane et al, 2012;Molli et al, 2015;Omeje et al, 2013;Omeje et al, 2014;Rotimi et al, 2014;Sunmonu et al, 2015;Aizebeokhai et al, 2016;Sunmonu et al, 2016;Joel et al, 2016;Muhammad and Khalid, 2017;Poongothai and Sridhar, 2017;Umar et al, 2017).…”

Groundwater is a vital natural resource that plays a significant function in sustainability of living things on earth. Its exploration requires special skill for optimum exploitation. Shuttle Radar Topography Mission (SRTM)and Vertical Electrical Sounding (VES) were used to detectthe stratigraphy and subsurface structures controlling the groundwater system around Iju -Ota, Ogun State, Southwestern Nigeria. Nineteen (19) VES points were carried out where there were dense concentrations of lineaments and interconnected to establish the connection of the observed lineaments with groundwater occurrence in the study area using Schlumberger array, with electrode spacing of AB/2 varying from 180 to 320 m. The analysis of SRTM data revealedthe dominating structural NE-SW and NW-SE trends, which control aquifer structure. The geoelectrical parameters from the VES results were used to map the stratigraphic sequences in the study area. Six (6) units that comprisethe topsoil, lateritic clay, clayey sand, mudstone, sand (main aquifer), and shale or clay were identified in the study area. The aquiferous unit around Iju -Ota axis ranged from 30 to 80 m. Theextracted from the hill shaded SRTM data and the result of VES revealed that the thickness of the aquifer is as a result of interconnectivity of the lineaments observed in the SRTM data suggesting that the groundwater occurrence in the study area is chiefly controlled by these fractures.

AbstrakIdentifikasi ketebalan tanah gambut telah berhasil dilakukan menggunakan metode geolistrik resistivitas. Informasi ini sangat penting untuk mitigasi penyebaran lindi dan proses pengembangan pembangunan Tempat Pembuangan Akhir Batu Layang. Pada penelitian ini, dibuat 6 buah lintasan yang memiliki panjang masing-masing 117 m dengan tiga lintasan memotong tiga lintasan lainnya. Dari hasil penelitian, diperoleh nilai resistivitas pada lokasi penelitian sebesar (1,0703 -706,6) Ωm. Tanah gambut diidentifikasi pada kedalaman (4 -7,6) m dengan nilai resistivitas sebesar (40 -706,6) Ωm. Hasil ini telah divalidasi dengan sampel tanah yang diambil dari dua titik pengeboran hingga kedalaman 5 m. Berdasarkan hasil pengeboran tersebut, ketebalan tanah gambut sebesar 4 m dan 4,5 m. Selanjutnya, dari penampang resistivitas 2D, dibuat model resistivitas 3D menggunakan metode interpolasi inverse distance. Model resisitivtas 3D memberikan informasi sebaran ketebalan tanah gambut pada lokasi penelitian.

“…However, the interpretation of these electrical survey data is done in situ and improved by expensive software that is not always available to develop country research institutes such as Côte d'Ivoire. Thus, the method of the inverse slope suggested by (Sankarnaryan & Ramanujachary, 1967), free of access and easy to use, and take over Mondal et al (2008), Karuppannan (2015), Poongothai & Sridhar (2017) in India and Kouassi et al (2017) in Côte d'Ivoire in granitic formations, will be tested in the Bouna department which presents similar geological contexts.…”

The inverse slope method (ISM) was used to interpret electric sounding data to determine the geoelectric parameters of the alteration zones (continuous media) and rocky environments (discontinuous environments) of the Bouna Department. Having both qualitative and quantitative interpretation, the inverse slope method (ISM) has the ability to determine the different geoelectric layers while characterizing their resistivities and true thicknesses. In the Bouna department, this method allowed us to count a maximum of four (4) geoelectric layers with a total thickness ranging from 12.99 m to 24.66 m. The alteration thicknesses calculated by the ISM in comparison with those measured in the boreholes showed a linear agreement of the coefficient of determination R 2 = 0.8269 with the support of the Nash criterion which showed that this method gave thicknesses of alteration close to 76.76% of that obtained during the drillings.
