“…Structuraly, the geoelectrical layer displacement along the constructed geoelectrical cross-section can be attributed to subsurface faults. It is worth mentioning that the projection of the deduced faults is controlled by the observed surface structures and geological map of the study area (Abdel-Meguid et al 1998). Figure 7 shows the bedrock depth map over the study site here the depth of rock ranges from 1.2 m at DC sounding no.…”

“…Structural studies indicate that the study area subjected to major and minor normal faults and fractures trending in the NW and NE directions and the NW one is dominant with caves and sinkholes (Abdel-Meguid et al 1998;Shebl et al 2019). Most of the caves are distributed along major faults with different sizes and their lengths range from some meters to more than one kilometer.…”

“…Minia Formation consists of succession intercalated chalk and limestone which are cross-bedded and containing flint and chert at its bottom (Abdel-Meguid et al 1998). The top consists of hard massive and karstic limestone with numerous vugs, holes and caves which are sometimes connected with each other.…”

The new urban development is an important priority in Egypt to face a rapid increase in the population during the last few decades. As a case study, the geotechnical assessment of the New Minia City is studied applying direct current (DC) resistivity technique. In the presented study, the DC resistivity data are interpreted to (i) characterize the subsurface layer distributions, (ii) deduce the subsurface structures considering the surface geological and structural setting and borehole information and (iii) predict geotechnical parameters of the bedrock based on empirical relationships. The inversion results of DC resistivity data indicate that a lens of clay is locally capping the fractured limestone in different parts of the area. The constructed geoelectrical cross-sections show that the limestone bedrock is highly fractured regarding many normal faults trending in the NW and NE directions. In an attempt to derive empirical relationships for predicting the geotechnical parameters, the inverted resistivity values of the fractured limestone were correlated with different geotechnical parameters, Rock Quality Designation (RQD) and Unconfined Compressive Strength (UCS). It is noticed that there are good correlations between the limestone resistivity values and geotechnical parameters obtained from borehole data applying linear relations. Accordingly, the results indicate that the DC resistivity method constitutes a valuable technique to introduce a preliminary geotechnical assessment for new urban areas.
