Uncertainty in Probabilistic Open Pit Slope Stability Analyses: Implications for Reliability-Based Designs
DownloadSpring 2024
The presence of uncertainty is acknowledged in various fields of Engineering. Also, there are many sources of uncertainties. In geotechnical engineering, probabilistic slope stability analysis (PSSA) is a tool used to quantify parameter uncertainty. It achieves this by considering any strength...

Villalba Matamoros, Martha Emelly
Analysis of uncertainty in ore reserves impacts investment decisions, mine planning and sampling. Uncertainty is evaluated by geostatistical simulation and is affected by the amount of data and the modeling parameters. Incomplete uncertainty is given because the parameter uncertainty is ignored....

Uncertainty in well-to-tank with combustion greenhouse gas emissions of transportation fuels derived from North American crudes
Download2017-01-01
Di Lullo, Giovanni, Zhang, Hao, Kumar, Amit
Many studies have calculated deterministic point estimates of well-to-combustion (WTC) emissions of transportation fuels from crude oil in an attempt to determine which crude oils have lower or higher emissions. However, there is considerable variation in the published results, resulting in...

This thesis sets out a workflow to quantify uncertainty of the Arrow Deposit, a tabular, vein type, high-grade, basement-hosted, uranium deposit located on NexGen Energy Limited’s 100%-owned Rook I property in northern Saskatchewan. The uncertainty associated with the volume, grade, and density...

Spring 2022
Estimating costs for construction projects is a complex and often uncertain process. Given the inherent uncertainty of estimating and the unique risk profile of each construction project, many owners use cost uncertainty analysis to understand a project’s range of potential costs. Since results...

Unsaturated Flow Model
2019-06-06
Xiaochuan Tony Zheng, Tony Zheng
The un-saturated flow sub-model is based on a previously developed infiltration-drainage model. This research improves the original model by adding capabilities of handling dynamic boundary conditions and inter-layer overflow mechanisms. Additional validation cases are conducted to build...

Use of an Acoustic Location System to Understand Songbird Response to Vegetation Regeneration on Reclaimed Wellsites in the Boreal Forest of Alberta
DownloadFall 2017
Limited information exists on the recovery of different ecosystem components following reclamation of oil and gas wellsites in the boreal forest of Alberta. Songbird response to wellsite reclamation efforts in the boreal forest was previously unexamined, despite the abundance of wellsites,...

Spring 2010
This research determined if woody debris amendments facilitate land reclamation after oil sands mining. Specifically, it assessed if woody debris affects vegetation cover and richness, woody species survival and abundance, soil nutrients, temperature and water, microbial biomass carbon and...

Water availability and understory influence on tree growth in reclaimed forest ecosystems, Athabasca oil sands region, Alberta, Canada
DownloadFall 2015
Reclaimed forest ecosystems in the Athabasca oil sands region (AOSR) have limiting factors to growth that can result in poor tree performance, as indicated by stunted growth, foliar discolouration and needle dropping, and ultimately threaten reclamation success. Indicators of reclamation success...

Fall 2011
Oil sands mining in Alberta will destroy tens of thousands of hectares of boreal habitat. This land will need to be reclaimed. Current closure plans call for the construction of shallow open water wetlands to cover about 10-30% of the reclaimed landscape. Already, several trial wetlands have...
