Spring 2020
Soil stockpiles are used around the world to reclaim sites affected by industrial activities. Oil sands surface mining and in situ extraction activities in Alberta, Canada, have directly impacted more than 900 km2 of land, with more development expected in the future. Soil stockpiles will be...

Improving forb establishment and restoring soil function in disturbed landscapes: Hitchhiking native forbs with white spruce
DownloadSpring 2018
Changing requirements for land reclamation in Alberta has led to the need for revegetation of disturbed lands with native woody and herbaceous species. Our study involves âHitchhiker Plantingâ which is similar to companion cropping in agriculture, with the goal of improving native forb...

Influence of Amendments and Soil Depth on Available Nutrients and Microbial Dynamics in Contrasting Topsoil Materials Used for Oil Sands Reclamation
DownloadFall 2015
As of December 2013, the cumulative area disturbed by oil sands mining in NE Alberta was 896 km2 out of an estimated final footprint of 4,800 km2 – all of which will require reclamation. Expensive handling costs and scarce soil resources necessitate judicious management and application of...

Influence of Environmental and Site Factors and Biotic Interactions on Vegetation Development Following Surface Mine Reclamation Using Coversoil Salvaged From Forest Sites
DownloadSpring 2017
Industrial activities such as surface mining are responsible for disturbing large areas of forest land. Reclamation methods must facilitate the development of soil, of a diverse natural understory plant community, and of a tree canopy. In my thesis research, I examined the response of vegetation...

Influence of Soil Cap Depth and Vegetation on Reclamation of Phosphogypsum Stacks in Fort Saskatchewan, Alberta
DownloadSpring 2013
This study quantified environmental parameters to develop reclamation strategies for phosphogypsum stacks. Research was conducted on phosphogypsum stack experimental plots established in 2006 (6 soil cap depths, 5 vegetation treatments), and soil capped slopes seeded in 1998. Significant root...

Integrity Assessment of Dents in Pipelines using Finite Element Analysis and Artificial Neural Networks
DownloadFall 2019
Dents are common occurrences along oil and gas pipelines and can be formed due to pipe contact with external forces such as rocks or construction equipment. There are many factors that contribute to the level of integrity concern of a dent including its shape, size, location on the pipe, and...

Fall 2016
Slurry pipelines are widely utilized in most mining operations to transport the raw materials and the tailings. These pipelines typically suffer from high wear rates. For example, in Canada’s oil sands industry, pipeline wear rates of 1 cm/yr are considered representative. To generate and measure...

Investigation of Corrosion and Crack Morphology Behavior under Disbonded Coatings on Pipelines
DownloadFall 2015
Coating disbondment on pipelines is a common phenomenon that leads to exposure of the pipeline metal to the surrounding soil and ground water solutions. The exposure of pipelines to those corrosive environments is associated with development of corrosion and Stress Corrosion Cracking (SCC) on the...

Marsh reclamation in the oil sands of Alberta: providing benchmarks and models of vegetation development
DownloadFall 2014
A key objective of the Alberta oil sands industry is to reclaim the post-mined landscape to “equivalent land capability” (Harris 2007). Vitt and Bhatti (2012) proposed a restoration framework for boreal disturbances. They suggested that to increase chances of achieving ecosystem equivalency and...
