AbstractDouglas Channel is a 100-km long fjord located in northwest British Columbia with the town of Kitimat and Kitimaat village located at its head. The Geological Survey of Canada, as part of Natural Resources Canada's Public Safety Geoscience Program, provides baseline geoscience information to help inform stakeholders and decision-makers. The main objective is to map the surficial geology and occurrence of landslides along the bordering slopes of the fjord. The mapping to identify the types of landslides and substrate on which they were triggered was carried out mainly by stereoscopic interpretation of medium-scale aerial photographs, augmented with some pre-existing field observations. LiDAR surveys also helped fine-tune interpretation in some of the areas. In addition, terrain stability assessment using the standardized method developed for the BC forest industry was carried out. This baseline geoscience information is the first step in developing landslide susceptibility modelling for the fjord.
Summary(Plain Language Summary, not published)
A proceedings paper for the GeoVancouver conference led by the Canadian Geotechnical Society (Oct. 2016) highlighting preliminary results on landslide inventory and susceptibility mapping along Douglas Channel, a 100 km fjord located west if Kitimat, British Columbia.
