Project Title

Development of a methodology for the design of low-impact drainage systems along transportation infrastructure in permafrost environments

 

Description of the project research

One of the main causes of embankments degradation in northern Canada is the heat transferred by surface runoff and groundwater under the transportation infrastructures. Currently, engineering methods for the design of drainage systems are limited to a set of “good practice” recommendations to avoid excessive heat transfer under embankments. The project intends to develop practical methods to calculate the quantity of heat transferred through convective surface and sub-surface water flows in the design of a drainage system. In particular, a method to assess the maximum quantity of water that can be concentrated in one channel in order to control heat transfer to permafrost and erosion of soils will be developed. The approach will lead to the optimal number of crossings (culverts) to consider for a given structure, the thermal design of these crossings as well as the need and the design of an appropriate flow diffusion system downstream from the structure. The project involves soil temperature profile logging as a function of water flow, heat flux measurements, thermal modelling and small scale laboratory testing. Field work will be done at one Nunavik site in Salluit as well as at several sites in the Yukon (Beaver Creek; Alaska highway) and in the North-West Territories (Highway 3).
