ASSESSMENT OF CLIMATE CHANGE IMPACTS ON INFRASTRUCTURE IN ALL NWT COMMUNITIES

Posted on

Communities in Canada’s North in general, and the Northwest Territories (NWT) more specifically, are facing unique challenges regarding climate change adaptation. Not only are they experiencing climate change impacts at an accelerated rate compared to what is observed globally, but they are also exposed to a vast quantity of climate induced hazards affecting weather (e.g. droughts, high winds), ground stability (e.g. permafrost degradation, coastal erosion) or coastal and riverine environments (e.g. sea level rise or fluvial flooding) due to its … Read more

INUVIK AIRPORT CLIMATE CHANGE VULNERABILITY ASSESSMENT

Posted on

BGC Engineering Inc. (BGC) was retained by Transport Canada (TC) to carry out an assessment of northern airports and their vulnerability to climate change. As part of this work a climate change vulnerability assessment was carried out for Inuvik’s Mike Zubko Airport located in the continuous permafrost zone of the Northwest Territories in Canada. The assessment looked at a 30-year projected trends for the Inuvik region, which are based on historic climate data and climate projections using climate models. Attachments … Read more

GOVERNMENT OF NORTHWEST TERRITORIES – HIGHWAY 3 WEST OF YELLOWKNIFE

Posted on

The Public Infrastructure Engineering Vulnerability Committee (PIEVC) has developed a standardized protocol to assess the vulnerability of Canada’s public infrastructure to climate change. Case studies have been carried out to date across Canada, testing and calibrating this protocol on various infrastructures. This report presents the results of the case study undertaken for a 100 km section of Northwest Territories’ Highway 3 located between Behchoko (Rae-Edzo) and Yellowknife (km 240 to km 333). The principal objective of this vulnerability assessment is … Read more

GOVERNMENT OF NORTHWEST TERRITORIES THERMOSYPHON FOUNDATIONS IN WARM PERMAFROST

Posted on

Passive cooling by means of pressured heat exchange pipes was developed in Alaska by the U.S. Army Corps of Engineers in 1965 to preserve foundations in ‘warm’ permafrost. It has been widely applied in Alaska, northern Canada and Russia to preserve and cool permafrost. The original simple 20mm vertical pipe with a radiator in the air has evolved into other designs that include: thermopiles, sloped pipe thermosyphons and flat loop evaporator pipe (flat loop) thermosyphons. The flat loop thermosyphon was … Read more
