“…Modomo/Kajola is a quite fresh community in the ancient town of Ile-Ife, Osun State. As a result of its closeness to two main tertiary institutions of the Obafemi Awolowo University (OAU), Ile-Ife, and Oduduwa University, Ipetu-modu (OUI), it is reported that the community is experiencing a fast rise in population and development (Oni et al, 2020). The growth in population and development of properties in the community was due to an increase in requests for accommodation by staff and students of these institutions and other residents.…”

“…The increasing population density and subsequent increase in the water requirement of the community had also led many to explore alternative water source(s) as the public water supply is virtually non-existent. According to Abuzied and Alrefaee (2017); Chirindja et al (2017); Oni et al, (2020) people or inhabitants in the community, in developing countries, rely mostly on groundwater as a source of potable water supply. This is because groundwater sources can be developed nearby the location/site of need or demand while shallow water is susceptible to pollution and very expensive to develop a dam for even distribution.…”

This study is intended at depicting the aquifer plausible zones in Modomo/Kajola, Ile-Ife using Dar Zarrouk parameters. The study area is situated amid latitudes 830,00–830,500 mN and longitudes 663,500–664,000 mE, overlying pegmatite and granite gneiss in the basement complex terrain. Twenty-eight (28) Schlumberger-array vertical electric soundings (VES) were carried out within the study area with the help of Terrameter SAS 300C. The VES interpretation result reveals three to five geo-electric layers: topsoil, clay/sand/lateritic layer, weathered layer, fractured basement, and fresh basement. The geoelectric sections showed the main aquifers to be unconfined, semi-confined, and confined composed of sandy clay, clayey sand, and sand with different thicknesses (aquifer thickness varying from 3.3 m to 15.8 m with a mean value of 9.9 m). The aquifer hydraulic characteristics show that the longitudinal conductance (L) varies from 0.014 Ωm to 1.000 Ωm with a mean value of 0.132 Ωm, the transverse resistance (T), varies from 677.4 Ωm2 to 6465.7 Ωm2 with a mean value of 2291.2 Ωm2. The Hydraulic conductivity (K) values vary from 29.4 m/day to 126.9 m/day with a mean value of 50.5 m/day. The transmissivity (Tr) values attained at many layers vary from 418.7 m2 /day to 465.1 m2 /day, with a mean value of 449.4 m2 /day. The GSLI values vary from 2.25 to 4.25 with a mean value of 2.9. Three aquifer plausible zones were depicted involving sandy clay, clayey sand, and sand.

“…The magnetic method is probably the most versatile of all the geophysical methods (Dobrin and Savit 1988) because it can be applied to both shallow and deep seated targets. Magnetic method has emerged a powerful tool in groundwater prospecting in recent years due to its ability to reveal lineaments (folds, faults, joints and fractured zone) which may serve as openings for groundwater accumulation and storage (Oni et al, 2020;Abdulkareem et al 2018). The lineament derived from aeromagnetic data is superimposed with the lineament from remote sensing data to generate a combined lineament map for the study area using the ArcGIS tool for more accurate groundwater potential zone delineation.…”

This research combined remote sensing, geology and geophysical methods, fifty five (55) Vertical Electrical Sounding was carried out in the study area for proper groundwater potential investigation. In order to map groundwater potential of the area, eight thematic factors that influence groundwater occurrences and movement such as geophysical data (aquifer transmissivity, hydraulic conductivity, overburden thickness, recharge rate and aquifer resistivity), geologic data (lithology) and remote sensing data (slope and lineament) were ranked based on technique for order of preference by similarity to ideal solution (TOPSIS) and the developed Fuzzy technique for order of preference by similarity to ideal solution (FTOPSIS). The groundwater potential model map was evaluated using the developed FTOPSIS (Fuzzy Technique for Order of Preference by Similarity to Ideal Solution) and conventional TOPSIS. The groundwater potential of the area of study was qualitatively classified into five classes, namely; very high, high, moderate, low, and very low which account for 19%, 21%, 23.5%, 31.5%, and 5% of the total area respectively. The quantitative validated result of the developed GPM map (FTOPSIS) using the Receiver Operating Characteristics (ROC) technique, yielded the result of 0.84 which indicates 84% prediction accuracy while the prediction rate for the TOPSIS based model 0.75 representing 75% prediction accuracy respectively.
