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 ... -
SWELLING AND PERMEABILITY OF COMPACTED BENTONITE WHEN HYDRATED WITH A MULTICOMPONENT HYPERSALINE PORE FLUID
The swelling properties and permeability of compacted bentonite when hydrated to a multicomponent, hypersaline fluid (332 g/L total dissolved solids; 6.6 mol/L ionic strength) were quantified with laboratory experiments. ... -
Physical and numerical modeling of landslide-generated wave runup on steep slopes
Landslides generate waves when they fall into water, and these waves can be major hazards where they interact with coastlines and runup slopes on land. In this thesis, physical and numerical models of landslide-generated ... -
Performance of Geosynthetics for Remediation of Hydrocarbons and Emerging Contaminants
Diffusion of volatile organic contaminants through a thin (0.508 mm) seven-layer geomembrane including EVOH was evaluated using laboratory diffusion tests and compared to traditional polyethylene geomembranes. Using the ... -
Development and Influence of Erosion Voids at Rigid Pipe Joints
An experiment was designed and conducted to study the effect that erosion voids forming at leaky reinforced concrete pipe joints have on the pipe response to surface loading. The experiment consisted of a jointed system ... -
Distributed Sensing for Monitoring Cast Iron Pipe Behaviour
The objectives of this thesis were to investigate the material performance and field behaviour of small diameter cast iron water pipes. Exhumed pipes were provided by the Cities of Kingston, Hamilton, and Toronto in Canada. ... -
The Effect of Soil Gradation and Addition of Natural Fibres on the Mechanical Properties and Freeze-Thaw Durability of On-Site Manufactured Compressed Earth Blocks
Implementation of sustainable materials is becoming an imperative consideration in modern building because of the impact of the construction industry on climate change patterns. Building with earth is an ancient technique ... -
Assessment of Local Strains in Geomembranes at Gravel Indentations
Tensile strains that occur in geomembrane liners that are induced by local gravel indentations are investigated, with an emphasis on how the strains are calculated and what testing methods are used to obtain the deformed ... -
The Performance of Reinforced Concrete Pipe Joints under Differential Ground Settlement
Leakage from reinforced concrete pipe joints has negative environmental impacts and can compromise the sewer or culvert’s service life. Pipes can fracture, corrode, rotate, experience joint pullout, and potentially undergo ... -
Impacts of Warming Winters on Recharge in a Seasonally Frozen Bedrock Aquifer
(Elsevier, 2020-07-31)Under conditions of a changing climate, winters are predicted to be warmer and wetter in the northern hemisphere. Yet, the impacts of increasing midwinter snowmelt and rain-on-snow (ROS) events on groundwater recharge are ... -
Hydrogeologic and Climate Drivers of Water Isotopes in Fractured Rock: A Word of Caution for the Use of Groundwater Isoscapes in Humid Continental Settings
(Elsevier, 2020-03-16)Time-discrete groundwater isoscapes are commonly used as a proxy for the weighted mean isotopic value of precipitation and to infer recharge processes. In fractured rock environments, however, the complete removal of ...
