Abstract

Saskatchewan Department of Highways and Transportation (SDHT) implemented a Risk Management System for the provincial highway network in 2003, to prioritize sites for investigation and allocate resources for construction and maintenance. The Risk Management System identified a section of Provincial Highway No. 302, approximately 4.5 km west of Prince Albert, Saskatchewan, as an urgent site requiring immediate investigation and monitoring. As of April 2006, a 420 m of the highway was dropping as a result of large retrogressive landslides along the North Saskatchewan River. Daily inspection and monitoring of the site instrumentation were recommended until remedial measures could be implemented but the remote location of the site and high speed of landslide movement were not amenable to traditional means of inspection and monitoring. As a result, an automated real time monitoring and warning system was installed in the summer of 2005.This paper documents the site conditions and how the real time monitoring system has assisted in characterizing the landslide movement and managing risk at the site. For the covering abstract of the conference see ITRD number E211521.
