Summary(Plain Language Summary, not published)
Monitoring unstable slopes is a cost-effective hazard management practice to ensure resilient transportation infrastructure, for example, the national railway network. By monitoring seasonal variations in ground resistivity (to electrical currents), we define moisture paths and develop thresholds for the prediction of slope failure in the Thompson River transportation corridor.
