“…9 a indicates a strong correlation between permissible stress values and resistivity values for soils in the Maroua 1st locality.This suggests a very strong correlation. The second-order polynomial model used in the analysis resulted in a coefficient of determination (R 2 ) of 0.89 and a Spearman correlation coefficient (rs) of 0.85, both of which exceed 0.8.This finding is consistent with previous studies [ [34] , [35] , [36] , [37] ]. equation (5) below expresses the correlation between the two properties.…”

“…Notice, as the resistivity and the undrained shear strength of cohesive soils is plotted as a log-linear using a logarithmic scale on the x-axis, and a linear scale on the y-axis the linear regression line is curving. In the literature, other studies have tried to establish a relationship between electrical resistivity and geotechnical data, such as standard penetration test (SPT), dynamic cone penetration test (DCPT), Atterberg limit, triaxial compression, oedometer consolidation as well as the in situ vane test [51][52][53][54][55][56]. As in this study, they found that the relationships are area-specific, and the results cannot be transferred from one area to another.…”

The continuous growth of cities in combination with future climate changes present urban planners with significant challenges, as traditional urban sewer systems are typically designed for the present climate. An easy and economically feasible way to mitigate this is to introduce a Sustainable Urban Drainage System (SUDS) in the urban area. However, the lack of knowledge about the geological and hydrogeological setting hampers the use of SUDS. In this study, 1315 ha of high-density electromagnetic (DUALEM-421S) data, detailed lithological soil descriptions of 614 boreholes, 153 infiltration tests and 250 in situ vane tests from 32 different sites in the Central Denmark Region were utilised to find quantitative and qualitative regional relationships between the resistivity and the lithology, the percolation rates and the undrained shear strength of cohesive soils at a depth of 1 meter below ground surface (m bgs). The qualitative tests enable a translation from resistivity to lithology as well as a translation from lithology to percolation rates with moderate to high certainty. The regional cut-off value separating sand-dominated deposits from clay-dominated deposits is found to be between 80 to 100 Ωm. The regional median percolation rates for sand and clay till is found to be 9.9 × 10−5 m/s and 2.6 × 10−5 m/s, respectively. The quantitative results derived from a simple linear regression analysis of resistivity and percolation rates and resistivity and undrained shear strength of cohesive soils are found to have a very weak relationship on a regional scale implying that in reality no meaningful relationships can be established. The regional qualitative results have been tested on a case study area. The case study illustrates that site-specific investigations are necessary when using geophysical mapping to directly estimate lithology, percolation rates and undrained shear strength of cohesive soils due to the differences in soil properties and the surrounding environment from site to site. This study further illustrates that geophysical mapping in combination with lithological descriptions, infiltration tests and groundwater levels yield the basis for the construction of detailed planning maps showing the most suitable locations for infiltration. These maps provide valuable information for city planners about which areas may preclude the establishment of infiltration-based SUDS.

“…The amount of moisture has a significant impact on how the soil behaves. Therefore, the amount of the total soil volume that is occupied by the pore space, also known as soil porosity, and the moisture content from liquid limit occupy the same volume [13,16,60,64]. Hence, from ERT one can determine the soil porosity which is equal to liquid limit of that particular soil.…”
