“…Resistivity method is a geophysical approach based on the conductivity or contrast resistivity used to determine the conductivity distribution or resistivity of the Earth's substances below the surface, so this method is particularly suitable for identifying lithology units and variations in lithology units as well as for groundwater and aquifer studies (Redhaounia et al, 2016). Moreover it is one geophysical method that is low in cost, simple operation, and is efficient in areas with low contrast resistivity (Muchingami, 2012).…”

“…The geophysical method uses an approach based on the contrast of conductivity or resistivity to determine the conductivity distribution or resistivity of the subsurface Earth material, so this method is particularly suitable for identifying lithology units and variations of lithologic units as well as for the study of groundwater and aquifers (Redhaounia et al, 2016;Shen et al, 2020). In addition, this geophysical method is also a popular method because of its low operation cost, simple process, and efficiency in areas with low contrast resistivity (Muchingami et al, 2012).…”

Water is a unique property of the Earth and very important to every living organism. The existence of groundwater is only 0.61% of the total water on earth (oceans, rivers, lakes, polar ice, rain). The purpose of this research is to determine the location and depth of the aquifer by using 2D and 3D modeling. The method of research is resistivity method using Schlumberger configuration, where data is collected according to the survey design with coordinate ranging from X:436100, Y:9226880 to X:436680, Y:9227640, and covered by 7 lines. The modeling results indicate that the present groundwater aquifer potential has low resistivity distribution in this area. The spreading of unconfined aquifer is estimated on the north side to the east of Simpang 5 area. This can be seen from syncing the data of line one to six. But the data on line seven is of different patterns with other lines. The existence of groundwater basin is not easily identified on this line. This may be due to the location of Line Seven being located in the area of Ciputra Mall, Horison Hotel and Tlogorejo Hospital with higher consumption of water, thus the decrease in groundwater condition. This may cause conditions such as land subsidence. The results of interpretation based on the modeling show the possibility of an unconfined aquifer with groundwater level at 10-15 m depth with varied end of border groundwater depth.

“…Each protocol has its own characteristics in terms of depth of investigation, lateral and vertical resolution, horizontal coverage or signal length (Dahlin and Loke 1998). The Wenner array was used, due to its stronger signal-to-noise ratio and its high resolution on detecting salt water plume (Mcinnis et al 2013;Sauret et al 2015;Redhaounia et al 2016;Chabaane et al 2017b). In this study, the electrode spacing was set as 5 m, and 32 electrodes were used for ERT 1, ERT 2 and ERT 5 and 48 electrodes for ERT 3 and ERT 4.…”

The Maâmoura aquifer is located on the eastern coast of the Cap Bon peninsula. During recent decades, the agricultural exploitation of water has been strongly reinforced, causing an over-pumping of the groundwater resources accompanied by an intrusion of seawater. The geophysical approach based on electrical resistivity tomography has been adopted to obtain high-resolution electrical sections imaging, which allows delineatation of the areas characterized by a high salinization and reconstructs the geometry of the saline wedge front. In fact, the presence of seawater in the aquifers reduces subsurface resistivity values. In this study, five electrical profiles were performed using the Terrameter SAS4000 Lund Imaging System with an array of 64 electrodes. The Wenner configuration was used with a unit electrodes spacing of 5 m. Finally, we use hydrogeological data, and electrical resistivity tomography data superimposed with the location of wells to provide a conceptual framework for the understanding of the freshwater-saltwater interface in the Maâmoura region.

“…For these reasons, the use of technologies that integrate con-ventional methods with modern techniques of remote sensing and geographic information system (GIS) has been helping to increase the accuracy of hydrogeological research results, as well as to delineate potential groundwater zones in this type of region (Das, 2017). In turn, the use of geophysics in aquifer mapping and water quality assessment has also grown, due in large part to the positive results achieved, which are associated with advances in numerical modeling solutions (Sa;Elis, 2016;Redhaounia et al, 2016). Among the geophysical techniques that can assist in the identification of artesian wells in fractured aqui-fers, the multi-electrode resistivity method is one of the most widely used in geological studies.…”

Wells drilling process in fractured-bedrock aquifers is a difficult task. Extreme variations in lithology and structure features, as well productive water zones sited at preferential points make geological and geophysical investigations difficult. To contribute to the understanding of the process of groundwater zones occurrence in fractured-bedrock aquifers, this paper develops a drilling prospective model by using regression analysis, whose parameters were calibrated according to the photogeological and cartographic analysis of 113 drilling points in the states of Rio Grande do Norte, Paraíba, and Ceará. The effectiveness of the resulting model was assessed through a sample of 43 additional drillings, which were carried out aiming at the distribution of water to the communities in the semiarid region of Brazil. The obtained results indicate the model as an important tool in the drilling process, with direct implications on the logistics costs of water well site location and consequent attendance to the population that needs the water.
