“…Furthermore, upon closer inspection of these findings, it is evident that most of the variables have coefficients of variation that range from 0.12 for the liquid limit WL to 0.41 for the swelling amplitude εg. Based on the research conducted by Abdelmalek et al [ 29 ] and Mohammeda et al [ 9 ], this result is in line with factors that contribute to measurement errors in laboratory test methods. For instance, the coefficient of variation in relation to the fines percentage (0.05) is considerably lower than that of the plasticity index (0.16), confirming the difficulty of determining the Atterberg limits in comparison to the particle size analysis [ 30 ].…”

“…Different studies have investigated the correlation between geotechnical parameters and electrical resistivity. Mohammeda et al [ 9 ] showed that there is a good correlation between geophysical methods and geotechnical tests in the characterization of swelling soils. Sivelle [ 10 ] demonstrates that there is no direct correlation between electrical resistivity and dynamic tip resistance.…”

The change of mining stress often accompanies coal mining; these changes will affect the underground pressure water, destroy its original equilibrium state, increase the possibility of underground pressure water upward gushing, and then lead to the occurrence of mine water inrush accidents. A long-time monitoring system of mine water damage electrical information is developed to realize the long-time monitoring of mine underground pressure water. Based on the principle of resistivity tomography, this paper analyzes the method’s feasibility in inferring different geological distributions. Secondly, the long-time monitoring system of mine water damage electrical information is introduced. Finally, the stability and reliability of the instrument were proved by the simulation experiment, and the instrument was installed in the 17-33200 working face of Ping Coal No. 10 Mine, Pingdingshan City, Henan Province, China, for actual measurement to obtain the electrical information data of working face floor.

“…Two-dimensional surface electrical resistivity tomography (2-D surface ERT) is an advanced geophysical method producing true cross-sections of subsurface electrical resistivity [26,27]. It is well-suited to the investigation of heterogeneous and discontinuous aquifers [28][29][30][31][32] and continues to be widely used [33][34][35][36]. However, ERT equipment is expensive.…”

To improve borehole siting for rural water supply, an advanced resistivity method was adapted for developing country use and demonstrated in Malawi. The method was designed to be low cost, developing-country accessible, efficient. It allows single or multiple operators to acquire the multiple vertical electrical soundings (VESs) required that are inverted together in 2-D, to give a true cross-section of subsurface resistivity. Application at four sites generated true cross-sections of subsurface resistivity to around 100 m depth relevant to groundwater-resource investigation. A wide range of (hydro)geological features was identified, including fractured/weathered basement, gneiss domes, well-developed fault zones and several types of deltaic deposits. Imaging performance appears comparable to that of 2-D surface ERT (electrical resistivity tomography) that uses more expensive equipment, often unaffordable in developing countries. Based on the subsurface configurations determined and hydrogeological conceptualisation subsequently undertaken, the local aquifer potential could be evaluated, thereby providing a decision-making basis for future borehole siting at the sites surveyed. The technology is far superior to conventional 1-D VES, electromagnetic profiling or magnetic profiling currently used for borehole siting in Malawi. Technology adoption currently under consideration nationally would make use of existing VES capacity and permit much improved targeting of aquifer resource, more sustainable siting of boreholes and greater future resilience of Malawi’s rural water-supply infrastructure.
