Geophysical studies can be utilized adequately to decide the land, hydro geographical and geotechnical properties of the ground mass in which the designing development is occurring. The integration of the geophysical-traditional methods has appreciable potential for more accurate findings. The case studies mentioned in this review show the resistivity method's success and highlight the most important parameters that can control the method’s applicability and data interpretation. This review spots the light on the main results obtained from utilizing the electrical resistivity method and the most affecting parameters that can influence the obtained resistivity models, and also, focuses on published case studies to merge their findings to understand the interaction among the method, the foundation and the hosting background for buried foundations surveys. In particular, the electrical resistivity method has been performed in the context of buried foundation surveys. Geophysical methods provide an indirect way to look in the ground and provide information about the subsurface that the traditional methods might be unable to. Maintenance of existing structures and development or reuse of brownfield sites need to determine buried foundations, in terms of location and dimensions, as accurately as possible. This investigation will help in sustaining the slope stability via indicating the position of groundwater pathways, and thus implementing the slope remediation work. This study demonstrates the efficiency of application of electrical resistivity tomography (ERT) in detecting the groundwater pathways.
The interpretation of groundwater path is based on the resistivity values less than 100 ohm.m, which is interpreted as saturated materials. The resistivity data was analyzed using RES2DINV software. This study uses cable spread line at 200m with 2.5m spacing between electrodes by using gradient protocol.
In this study, Terrameter LS2 model, electrodes, cables, battery, and cable connectors were the equipment used for measurement. The groundwater path able to decrease the slope stability, thus its need to locate the position for conduct the slope remediation via subsoil drainage.
Geophysical electrical resistivity tomography (ERT) subsurface profiling was conducted to map the groundwater path along the embankment. Geophysical electrical resistivity method has been one of the more popular non-destructive method to explore the subsurface.
