This paper presents the applicability of Electrical Resistivity Tomography (ERT) in Subsurface Utilities Engineering (SUE). The objective is to use pseudosection generated by ERT to located known subsurface utilities. For construction industry, the investigation of subsurface utility is essential to avoid unforeseen condition that may cause project delay. According to the result, performing ERT using fundamental tester in this study is not suitable to locate subsurface utilities, however it can locate the loose part of the ground which likely to indicate the location of subsurface utilities. Therefore, ERT exhibits potential to be used before the actual subsurface utilities mapping to simplify the work of gathering information to locate the subsurface utilities accurately.

The Difference

Water percolation through infiltration ponds is creating significant synergies for the broad adoption of water reuse as an additional non-conventional water supply. Despite the apparent simplicity of the soil aquifer treatment (SAT) approaches, the complexity of site-specific hydrogeological conditions and the processes occurring at various scales require an exhaustive understanding of the system’s response. The non-saturated zone and underlying aquifers cannot be considered as a black box, nor accept its characterization from few boreholes not well distributed over the area to be investigated. Electrical resistivity tomography (ERT) is a non-invasive technology, highly responsive to geological heterogeneities that has demonstrated useful to provide the detailed subsurface information required for groundwater modeling. The relationships between the electrical resistivity of the alluvial sediments and the bedrock and the difference in salinity of groundwater highlight the potential of geophysical methods over other more costly subsurface exploration techniques. The results of our research show that ERT coupled with implicit modeling tools provides information that can significantly help to identify aquifer geometry and characterize the saltwater intrusion of shallow alluvial aquifers. The proposed approaches could improve the reliability of groundwater models and the commitment of stakeholders to the benefits of SAT procedures.
