EFFECT OF WETTING AND DRYING CYCLES ON THE PERFORMANCE OF MODIFIED AND NON-MODIFIED GCLS USED IN COVER AND BASE SYSTEMS AND UNDER HIGH HYDRAULIC GRADIENT
The effect of prolonged exposure to wet and dry cycles on the hydraulic performance of five different GCLs was studied. Three GCLs had polymer-modified bentonite and two GCLs had standard sodium bentonite. The GCLs were ... -
MODELLING COASTAL PROCESSES DRIVEN BY WINDS AND TIDES ACROSS A RANGE OF SPATIAL SCALES IN A MACROTIDAL BAY
The Bay of Fundy system in the Atlantic Ocean is a highly dynamic environment characterized by the highest tidal range in the world. The area contains a wide range of coastal environments and structures including salt ... -
Physical Testing and Numerical Modeling to Develop Design Equations for Corrugated Steel Culverts under Live Loading
This thesis investigates the structural behavior of corrugated steel culverts under live loading, through the use of field experiments and finite element modeling with the goal of developing design equations. An in-service ... -
EXPERIMENTAL ASSESSMENT OF FRP-CONFINED CONCRETE COLUMNS WITH DAMAGED JACKETS
Axial compressive strength of circular concrete-filled fibre-reinforced polymer (FRP) tubes (CFFTs) benefits greatly from significant concrete confinement by the tubes. Accidentally or deliberately induced damage to the ... -
Investigation of Winter Recharge in Vulnerable Bedrock Aquifers Under Climate Change
Many communities in cold regions depend on groundwater resources from shallow bedrock aquifers with thin overlying soil (0–5 m), yet these aquifers are vulnerable to surface contaminants and climate change impacts. The ... -
EVALUATION OF WHEAT STRAW, HAMMER-MILLED HEMP, RICE HULLS AND CELLULOSE SETTLEMENT BEHAVIOUR FOR LOOSE- FILL INSULATION APPLICATIONS
Straw bale construction has gained attention in the building industry for its purported sustainability and its low embodied carbon footprint. Research on straw bale construction has examined its thermal and structural ... -
ENERGY DISSIPATION FROM INTERNAL SOLITARY WAVES SHOALING ON FLAT AND MILDLY SLOPING BEDS
Abstract Boundary layer separation-driven near-bed instability beneath internal solitary waves (ISWs) of depression may be a significant source of wave-energy dissipation and drive localized mixing and resuspension in ... -
BUILDING RESILIENCE TO HIGH WINDS USING FRAGILITY ANALYSIS
North America gets hit with approximately 1,100 recorded tornadoes annually. In Ontario, Canada, more than 12 tornadoes are recorded between the months of May and September annually. Two major tornadoes hit Ottawa, Canada ... -
Laboratory Characterization of Turbulent Hyporheic and Free Surface Flows Associated with Bars in Gravel Streams and Related Efforts to Improve Measurement Techniques
Bars and pool-riffle sequences are common occurrences in gravel streams, and a major driving force affecting the exchange of groundwater and free surface water in upper river reaches. Such topographic features induce ... -
Structural Performance of Sandwich Concrete Walls including UHPC and GFRP Reinforcement under Bending and Axial Loads
This thesis investigates the structural performance of two sandwich walls; one suited for precast applications while the other for cast-in-situ. The first is an insulated double wythe design using very thin (25 mm) ultra ... -
Advanced Data Analysis Of In-Situ Bioremediation Site Data Using Dimensionality Reduction Techniques
Chlorinated solvents are one of the most prevalent groundwater contaminants in North America. Many of these contaminants are very difficult to clean up due to their physical properties and can pollute drinking water aquifers ... -
A Modeling Study of Large-Scale Solute Transport in Fractured Carbonate Rock
Fractures influence aqueous contaminant transport by allowing for rapid migration over long distances through complex pathways and through diffusion into the adjacent rock matrix. While there have been many studies examining ... -
A LABORATORY STUDY ON THE EFFECTS OF DISSOLVED GAS EXSOLUTION ON THE PERFORMANCE OF IN-SITU THERMAL TREATMENT TECHNOLOGIES
In-situ thermal treatment (ISTT) technologies are a set of remediation methods for treating chlorinated volatile organic compound (CVOC) dense non-aqueous liquid (DNAPL) source zones by increasing the temperature of the ... -
FACTORS AFFECTING GCL SELF-HEALING AND ITS SUBSEQUENT HYDRAULIC PERFORMANCE
A number of researchers have studied GCLs’ self-healing capacity, however, most examined either regular holes or relatively benign hydrating/permeating fluids not representative of typical field applications. This thesis ... -
Stray Gas Migration: Multicomponent Mass Transfer Effects on Dissolution and Persistence of Gas in the Subsurface
As the development of deep geological gas reserves increases in the coming years, concern has been raised regarding potential environmental impacts including stray gas migration. The goal of this research was to improve ... -
USING BIOGEOCEMENTATION TO REDUCE PHYSICAL INSTABILITY AND WIND EROSION OF MINE TAILINGS
The mining industry in Canada is an essential driver of economic growth as societal demands for minerals increases with advances in technology. The waste generated through these mine operations is one of the biggest ... -
Mechanisms of particle-liquid interaction in high-mobility debris flows
Debris flows are a category of fast-moving landslides with the potential for exceptionally long travel distance. The transition from a geomaterial to a viscous fluid has garnered attention from many fields of research, ... -
Interface shear behaviour of different geomembranes with rough surfaces in Heap Leaching applications
The interface shear strength properties of the different geosynthetic layers of the liner system are examined for heap leach pads applications. A series of large scale direct shear tests is used to examine the effectiveness ... -
A DATA BASED STUDY OF ASPECTS OF THE GEOMETRY AND MECHANICS OF MEANDERING STREAMS
The present study explores aspects of the geometry and mechanics of meandering streams based on a significant dataset consisting of laboratory and field observations. The work focuses on three main issues that, despite ... -
Numerical Modelling of Wind-driven Hydrodynamics in Shallow Wastewater Ponds and Coastal Estuaries
Throughout the world, shallow water (<5 m) environments, including ponds and estuaries, provide vital contributions to regional economies and environments. Despite their prevalence and importance, questions remain about ...
