The characterisation of the subsurface a landslide is critical step in developing ground models that inform planned mitigation measures, remediation works or future early-warning instability. When failure may be imminent, time pressures on producing such great. Geoelectrical and seismic geophysical surveys are able to rapidly acquire volumetric data across large areas at slope-scale. However, analysis individual model derived from each survey typically undertaken isolation, robust, accurate...
Landslides in the Thompson River Valley, British Columbia, Canada, threaten serviceability of two railway lines that connect Vancouver to rest Canada and US. To minimise impact slope instability on vital transport infrastructure, as well terrestrial aquatic ecosystems, public safety, communities, local heritage, economy, better inform decision making, there is a need for monitoring. Since 2013, Ripley Landslide – small, slow-moving, translational landslide has been focus monitoring efforts...
Electrical resistivity tomography (ERT) monitoring provides time-lapse images of the subsurface. These can be used to assess spatiotemporal variation in moisture content, which is a key driver slope failure, making ERT an effective tool evaluate precursory conditions failure. This work presents results on above major highway located border between England and Wales. During construction 1960s was subject several large landslide events resulted re-design carriageway installation engineered...
With the advances of ESA’s Sentinel-1 InSAR (Interferometric Synthetic Aperture Radar) mission, there are freely available remote sensing ground deformation observations all over globe that allow continuous monitoring natural hazards and structural instabilities. The Digital Environment initiative in UK aims to include these data effort at forecasting mitigating across UK. In this paper, we present a case study Hollin Hill landslide North Yorkshire where variety ground-based geophysical...
Abstract. We summarise the contribution of geophysical imaging to local landslide early warning systems (LoLEWS), highlighting how design and monitoring components LoLEWS benefit from enhanced spatial temporal resolutions time-lapse imaging. In addition, we discuss with appropriate laboratory-based petrophysical transforms, data can be crucial for future slope failure forecasting modelling, linking other methods remote sensing intrusive across different scales. conclude that in light...

Summary Landslides are complex and heterogeneous phenomena involving properties of the subsurface. To study landslide processes, we use self-potential (SP) method to investigate physical characteristics subsurface monitor accumulation movement groundwater associated with reactivated landslides at Hollin Hill, UK. The SP measurements consist mapping in 2D monitoring profiling. Six mappings acquired different climatic conditions. They show positive charges carried direction fluid flow,...
Robust and timely assessment of the condition geotechnical infrastructure assets (e.g. cuttings, embankments, dams) is essential for cost effective maintenance engineering interventions to prevent failure events. Infrastructure slopes (in transportation, utilities water management) are experiencing increasingly high levels require considerable resources maintain; in order hundreds millions pounds per year UK alone. The issue accelerating asset deterioration being exacerbated by greater...

Here we consider: (1) development novel geoelectrical, seismic...

Therefore, effective tools are required for landfill characterization to be able identify landfills with high priority remediation potential mining. In contrast conventional ground-truth methods, geophysical methods relatively inexpensive and since they minimally invasive, entail less risk contamination.
