AbstractThe mandates of Inter-Departmental Letter of Agreement 4755 (IDLA-4755) and Inter-Departmental Memorandum of Understanding (IMOU-5170) between Natural Resources Canada (NRCan), Geological Survey of Canada (GSC), and the Transport Canada Innovation Centre (TC-IC) are to research and monitor landslides where vital railway infrastructure and operations, public safety, natural resources, and the environment are at risk. Research activities in the Thompson River valley railway corridor from 2013-2020 are reported herein, including: i) an ongoing proactive infrastructure monitoring and evaluation (PRIME) survey in collaboration with the British Geological Survey (BGS); ii) monitoring with a developmental global navigational satellite system (GNSS); iii) high-resolution photogrammetric change detection using unmanned aerial vehicles (UAV) and commercially available software; and iv) fine and ultra-fine resolution mapping of Thompson River using RADARSAT-2 and SENTINEL-1 synthetic aperture radar (SAR).
Summary(Plain Language Summary, not published)
Natural Resources Canada, the Geological Survey of Canada, and Transport Canada Innovation Centre are researching and monitoring landslides where vital railway infrastructure and operations, public safety, natural resources, and the environment are at risk in the Thompson River valley, British Columbia, and the Assiniboine River valley along the borders of Manitoba and Saskatchewan. A bibliography includes all reports related to IDLA-4755, and publications in preparation. Activity goals achieved from 2013 to 2020 are summarized in Appendix 1.
