“…1. An aquifer is a distinctive geological formation, despite the fact that some are extra established than the other [23]. The boundaries of an aquifer are typically gradational into some other aquifer in order that an aquifer may be a part of some other aquifer system.…”

“…The thickness of the weathered overburden and the fractured zones determines the strength of groundwater dynamics. In order to identify appropriate locations for these aquifers in the basement complex, it is imperative to integrate the geological and hydrogeological knowledge of the area of interest with the geophysical survey (preferably electrical resistivity method using Schlumberger array and/or electromagnetic method) [4,10,23]. Groundwater that is free from pollution (through anthropogenic activities) can be exploited within faulted bedrocks at great depth while the aquifer within weathered layer is usually occur at shallow depth that is prone to pollution.…”

Groundwater includes water that is formed within the unsaturated zone (soil), above the water table (capillary fringe) and below the water table. Its occurrence is everywhere, and it is restricted to a maximum of 750 m depth in the near surface. Groundwater availability within the subsurface formation has become a primary concern to the geoscientists because the dependency of surface water has been limited and declined due to it inadequate yield during the period of a year and also the surface contaminant which affect its quality and potential. The investigation of groundwater in the near surface has been a major principal discovery which has served both the domestic, commercial, agricultural and industrial purposes and to understand the continuity of groundwater availability within the subsurface, a study on occurrence and flow of groundwater is highly significant. Understanding the flow pattern is a major constituent in productive groundwater exploitation and exploration. Therefore, this review has been design to place emphasis on the occurrence and flow of groundwater in the near surface, which is one of the agenda of the Sustainable Development Goals.

“…This method utilizes lightning activity in the ionosphere as its source with a frequency range from 0.1 Hz-10 kHz (Constable, 2016), which is both environmentally friendly and easy to use. The AMT method is used in hydrology to determine aquifer thickness and depth, to define the deepest geological strata, and to characterize groundwater migration (Li et al, 2021;Montahaei, 2022;Tripathi et al, 2019;Xu et al, 2020;2023;Zaher et al, 2021). The expected result of using AMT method in this research is to determine the presence of deeper aquifers based on the contrast of rock resistivity values modelled in 1D.…”

The Malabar Mountains area acts as a catchment and infiltration zone for rainwater. Haruman Peak is the location of one of these areas. Information on the well-preserved depth of the shallow aquifer at 40 meters reinforces this. This research reviews the results of subsurface 1D resistivity structures from AMT data to obtain information on the depth of deep aquifers on the western slope of the Haruman Peak Lava Fan, Haruman Mountains. 1D modelling shows an aquifer at depth of 140.56-2080.07 meters with resistivity ranging from 5.25-68.08 Ωm. At depths of 453.32 m (HR02), 530.8 m (HR03), 1464.97 m (HR01), and 2080.07 m (HR02), interbedded tuff-andesite with minor pumice identifies the deep aquifer. In addition, a depth of 140.56 m (HR02) with a resistivity value of 68.08 Ωm indicates a shallow aquifer. Looking at the elevation of the Bandung Basin, water from aquifers located at elevations > 700 meters above sea level will flow into the Bandung Basin.

“…The current study focuses on the delineation and characterization of the groundwater potential zones in the north Omdurman area using vertical electrical sounding techniques combined with lithological logs. Several successful works have been reported in the literature on using the VES method in hydrogeological studies to delineate the potential zones of groundwater or to measure the hydrogeological parameters [19][20][21][22][23][24][25]. The advantage of using geophysical methods over the other methods in aquifer delineation is that they are quick and cost-effective.…”

This study is conducted in the northern Omdurman area to delineate groundwater potential zones using electrical resistivity method. Omdurman is the most ancient city known as the historical capital of Sudan. Geoelectric survey employing vertical electrical sounding (VES) technique is carried out to explore the availability of groundwater in the study area. The measurements were conducted using Schlumberger configuration. In this study, twelve VES points are measured along four profiles. The measured data is processed and interpreted using 1D geophysical inversion technique constrained by lithological data obtained from two boreholes. The integration of electrical and geological data led to a reliable interpretation of the geophysical model. The obtained results revealed that the geological succession of the study area is mainly composed of five layers of recent deposits, clay, sandy clay, silicified and ferruginous sandstone, and sandstone. According to the resulting hydrogeological sections, the water-bearing formation is composed mainly of coarse sandstone and varies in thickness under confined conditions. The geoelectrical sounding method successfully fulfilled the aims of the study. Nevertheless, detailed hydrogeological and geophysical investigations need to be carried out for a comprehensive characterization of the groundwater aquifer.
