In typical site investigations, borehole data offers localized information at specific depths within the borehole. It offers high vertical resolution but limited spatial coverage since it represents a point measurement. Electrical Resistivity Tomography (ERT) data, on the other hand, provides a continuous profile of subsurface resistivity distribution along a survey line or grid. It offers relatively high spatial coverage, capturing information between measurement locations. The study aims to understand on reliability of resistivity value with the soil or rock material information obtained from conventional borehole data located in Melaka, Malaysia. A resistivity lines were conducted ERT method with the Gradient XL protocol. Based on the results, high resistivity values were observed at first 5 meters, indicating the presence of Gravelly SAND and Silty SAND layers ranging from 5 to 6 SPT N-value. The resistivity value then decreases below 100 Ωm starting from a depth of 5meters and continuing until 9meters which indicate highly saturated layer. Then from a depth of 9 to 15 meters, the resistivity value increases, indicating the soil layer is less saturated with water due to its high resistivity value. It can be concluded that ERT data is reliable to represent subsurface data when comparing to borehole data. However, not all data can be fully understood or interpreted based on solely resistivity value especially around weathered materials. For instance, in area of immersed soil or rock, resistivity sometimes still gives higher value that is almost the same as in an unsaturated area. It was observed that the relationship of SPT-N and resistivity value is more consistent when the materials are in range stiff to hard layer.

“…In this relation, the role of monitoring and early warning is and will be more and more crucial in identifying the response of geo-structures to a changing climate. Some advances in monitoring of geo-structures exposed to climate change are discussed in [10,11] with special reference to the measurement of pore-water tension and water regime for embankments and slopes.…”

Climate Change Adaptation of Geo-Structures in Europe: Emerging Issues and Future Steps

et al. 2021

Climate change is already being felt in Europe, unequivocally affecting the regions’ geo-structures. Concern over this is rising, as reflected in the increasing number of studies on the subject. However, the majority of these studies focused only on slopes and on a limited geographical scope. In this paper, we attempted to provide a broader picture of potential climate change impacts on the geo-structures in Europe by gathering the collective view of geo-engineers and geo-scientists in several countries, and by considering different geo-structure types. We also investigated how geo-structural concerns are being addressed in national adaptation plans. We found that specific provisions for geo-structural adaptation are generally lacking and mainly come in the form of strategies for specific problems. In this regard, two common strategies are hazard/risk assessment and monitoring, which are mainly implemented in relation to slope stability. We recommend that in future steps, other geo-structures are likewise given attention, particularly those assessed as also potentially significantly affected by climate change. Countries considered in this study are mainly the member countries of the European Large Geotechnical Institutes Platform (ELGIP).
