Parameter Estimation and Well Installation Optimization for Contaminant Plume Delineation
Groundwater contamination by dense non-aqueous phase liquids (DNAPLs) continues to be a significant environmental problem. DNAPL site characterization forms the basis of DNAPL site remediation success and requires attention. ... -
Evaluation of Polygonal Hollow Structural Steel Sections via Experimental and Finite Element Analyses
Thin-walled hollow sections such as rectangular hollow sections (RHS) have very high torsional rigidity, and thus make a very economic choice for applications which are susceptible to lateral torsional buckling. However, ... -
Effect of Coating Defect, Desiccation, and Freeze-Thaw Cycles on Geosynthetic Clay Liner (GCLS) – Geomembrane Interface Transmissivity
A series of laboratory tests were conducted to investigate the effect of prehydration fluid, a 4-mm diameter central coating defect, coating defect position and nature, and the effect of coating orientation of a multi-component ... -
Biomass production and nutrient removal by Chlorella vulgaris as monoculture and in a consortium from centrate wastewater: optimization through acclimation
Microalgae-based wastewater treatment has shown promise in the removal of contaminants such as nutrients and heavy metals. Municipal wastewaters could be used as low-cost cultivation media as they provide the necessary ... -
The novel application of sensor technologies to monitor long-term vertical track displacement pre and post rehabilitation
Track geometry irregularities may induce travelling discomfort for passengers, vibration and noise, and critically redistribution of wheel loads causing derailments. To better understand the track deterioration mechanisms ... -
Testing A Full-Scale Reinforced Concrete Bridge Deck with GFRP and Steel Reinforcement Using Cyclic Pulsating and Rolling Loads
The repair and replacement of bridge decks represents a large portion of infrastructure spending. Gaining a better understanding of bridge deck behaviour through more representative vehicular loading can lead to a reduction ... -
Experimental Evaluation of Two Lining Methods Used for Pipe Rehabilitation
The goal of this research is to investigate two trenchless rehabilitation techniques, with the objective of developing a better understanding of potential failure mechanisms. The first experimental study involved the testing ... -
Physical Modelling of Tailings Dam Breach
Tailings dams are constructed in stages, exhibit sediment deposits located in the reservoir upstream of the dam crest (beaches) generated from slurry deposition, and are commonly designed with shallower upstream slopes in ... -
Mechanical Performance of PVC Pressure Pipes with a Bell-and-Spigot Joint
Water is a valuable resource for society, but it is not always used sustainably. In various cities across the globe, a great deal of water has been leaking from pipe networks, for example, due to corrosion-induced leakage, ... -
Stray Gas Migration in Shallow Groundwater: Gas Dynamics, Mass Transfer, and Environmental Expression
The objective of this research was to systematically investigate the dynamics of flowing subsurface gases, leading to understanding of mass loading of stray gas in unconsolidated sands, then couple this knowledge to ... -
Service Performance of a Cured In Place Polymer Pipe Liner for Deteriorated Cast Iron Pressure Pipes
Although Cured-In-Place Pipe (CIPP) liners have been used extensively across North America, their in-situ performance in deteriorated pipe conditions has not been extensively studied. The purpose of this research work is ... -
Modelling Methane Emissions from Arctic Lakes
Climate change in the Arctic is moving at a greater rate than the rest of the world, and the urgency of characterizing greenhouse gas emissions from water bodies located in high latitudes has become a subject of intensive ... -
Sustainable Masonry: Mortar Containing Biochar and Recycled Aggregate in Concrete Blocks
The building and construction industry is the third-largest producer of CO2 in Canada. Additionally, emissions from this industry are expected to go up by more than nine megatonnes of carbon dioxide equivalent (Mt CO2 eq) ... -
Mobilization of Non-aqueous Phase Liquid by Flowing Gas Bubbles in Porous Media
Gas bubbles can significantly affect contaminant transport in both sediments and groundwater systems. In some circumstances, gas bubble mobilization can result in the transport of non-aqueous phase liquids (NAPLs) as ... -
A Three-Dimensional Experimental and Numerical Study of Nearshore Hydrodynamics and Morphology Change on a Steep Sand Beach
Storm waves breaking on steeply-sloping sand beaches can generate strong currents across a narrow surf zone, and experience different rates of sediment transport and morphodynamic change compared to beaches with milder ... -
Heat Migration and Solute Transport in a Discrete Fracture
The study of heat and solute transport in fractured rock can provide complementary information in aid of understanding the interaction between surface and groundwater, the long-term isolation of energy by products, the ... -
Probabilistic Analysis of Unreinforced Slopes and Reinforced Footings Using the Random Finite Element Method
The focus of this thesis was on probabilistic analysis of unreinforced cohesive soil slopes and geosynthetic reinforced and unreinforced footings over cohesive foundations. Two open-source random finite element method ... -
Numerical Modelling of Methane Emissions From Peatlands
Peatlands could play a significant role in global warming for two reasons: 1) peatlands release methane (CH4), which is a very potent greenhouse gas estimated to be responsible for a quarter of the temperature rise the ... -
Simulating solute transport in discretely fractured rocks: Computational limitations and a hybrid method
To investigate the computational limitations arising when simulating large-scale groundwater flow and solute transport using a 3D control volume finite element model (the FE model) in discrete-fracture mode, numerical ... -
A Study of Aspects of the Coupling of Flow and Sediment Transport for Sand and Gravel Dunes
This work investigates the coupling between flow, sediment transport and changes to geometry of river dunes. It aims to broaden the understanding of this coupling by examining: a) intrinsic differences between flow and ...
