Peace River Urban Geology and Hazards Project
The town of Peace River has a large portion of its buildings and roadways built either on the flood plain or on the unstable valley walls of the Peace River Valley.
Project Goal
To understand the historical movement rates and extents, we will review deformation trends between 1992 and 2006 from an InSAR (Interferometric Synthetic Aperture Radar) study. These trends will be compared with deformations recorded using conventional instruments during the same period.
The results of these studies will give us an understanding of the relationships between ground changes and weather conditions. This will help us determine the probability of sudden or accelerated movement within the various landslide groups, in turn allowing for an overall risk assessment for landslides in the municipality.
As part of the work done for this project, all available geological, borehole and remote-sensing data for the project were gathered and integrated into a web-based viewing platform. Use our Peace River Web-GIS application and navigate through the data using the user-friendly interface developed in collaboration with the University of Alberta.
Project Background
In 2006, Alberta Geological Survey initiated a study to develop and understand the extent, rate and style of the large-scale landslides in and around the municipality. The first part of the study is to develop a 3-D geological model and complete an inventory of landslides in the area. This is necessary because of the geological (glacial) history of the soil and the various triggers that can initiate the landslides. Alberta Geological Survey and the University of Alberta will use this information to develop logical groupings for the landslide types that have occurred.
This initial focus will be complemented by the gathering and interpretation of airborne LiDAR (Light Detection and Ranging) sensor data from the spring of 2007, as well as field mapping performed by AGS staff in the summers of 2007 and 2008.
