Many of these assets were constructed over 100 years ago and are typically very poorly engineered compared to modern standards. These assets are experiencing increasingly high levels of failure and require considerable resources to maintain \u2014 hundreds of millions of pounds per year in the UK alone \u2014 a situation that is being exacerbated by the greater frequency of extreme rainfall events (e.g. winter 2013\u20132014, February 2020). <\/p>\n\n\n\n<p>Early identification of deteriorating condition generally allows low-cost preventative remediation to be undertaken and reduces the risk of catastrophic failures. However, conventional approaches (e.g. walkover surveys or intrusive sampling) to condition monitoring are often inadequate for predicting failure events.<\/p>\n\n\n\n<p>GTom is developing novel geophysical approaches to characterise and monitor geotechnical assets with the aim of improving asset management. The key benefits of geophysical methods such as ERT are that they can provide non-invasive spatial subsurface information; they can be very sensitive to moisture-driven deterioration processes, and they can be configured to enable remote condition monitoring of assets.<\/p>\n\n\n<div  class=\"accordions\">\n\t\t\t\t<div class=\"acc-wrap\">\n\t\t\t\t\t<button class=\"acc-top secondary-background icon-arrow button no-btn\"><span class=\"button-content\" tabindex=\"-1\">Key activities and projects<\/span><\/button>\n\t\t\t\t\t<div class=\"acc-body sea-background-e\">\n\t\t\t\t\t\t<p>The team has developed novel geophysical monitoring technology to enable cost-effective remote condition monitoring of assets.

This complements intrusive sampling methods, which typically provide information only at discrete locations. <\/p>\n\n\n\n<p>Provided that suitable resistivity contrasts are present, ERT has the potential to reveal mineral and overburden thickness and quality variations as well as discontinuities within the body of the deposit. In addition, ERT can be used to monitor the effect of groundwater abstraction and dewatering due to its sensitivity to changing moisture levels.

Consequently, many of the conventional investigative techniques (e.g. remote sensing; LiDAR; inclinometers) that rely upon such observations will not necessarily provide us with a prior warning of when the next failure event is going to occur. The reason for this is that such methods only monitor the physical expression rather than the causal process. <\/p>\n\n\n\n<p>As a team, we are interested in developing geoelectrical methods to investigate a range of processes relating to ground instability, including classical landslides and slope instability, sinkhole development, and even frozen ground (freeze\u2013thaw)-related hazards. A common link between many of these processes is the role of moisture-driven change in the subsurface. Our research is concerned with developing geophysical approaches to detect and characterise these processes, thereby providing early warning of surface expressions of failure.<\/p>\n\n\n<figure  class=\"img-wrap\"><a href=\"https:\/\/www.bgs.ac.uk\/wp-content\/uploads\/2020\/04\/EM_survey_landlide_Yorkshire.jpg\" data-toggle=\"lightbox\" data-footer=\"&lt;p&gt;Electro-magnetic survey of a landslide in Yorkshire, UK.
