  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 

  Wu, Jian

  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 

  Marmoush, Ramy

  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 

  Bou Jaoude, Issam

  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 

  Shafiee, Navid

  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 

  Wisheart, Caroline

  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 

  Campbell, Wesley

  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 

  Lockwood, Kenneth

  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 ...

• Shear Transfer Strength of Concrete After Exposure to Elevated Temperature 

  Yusuf, Md.

  The most consumed construction material in the world, concrete, is largely composed of coarse aggregate. Thus, the physical and mechanical properties of aggregates play a significant role in determining the performance of ...

• Turbulence and Sediment Resuspension Modelling in Lake Erie 

  Lin, Shuqi

  Physical and biogeochemical observation in Lake Erie, and a field-scale numerical model was applied to study the turbulent dissipation and mixing, sediment resuspension and bottom stress parameterizations. In Chapter 2, ...

• New Sensing Techniques for Improved Assessment of Rail Infrastructure 

  Barker, Christian

  As demand grows for rail transportation, so too does the stress on Canada’s rail infrastructure, and improved monitoring technologies are needed to prevent track failure and assist in the bridge rehabilitation process. ...

• The Development and Use of a Test Facility for Large Diameter Pipes 

  Mai, Van Thien

  This thesis examines the performance of a new deep burial facility through numerical modelling and physical experiments. A numerical investigation was conducted to investigate the influence of the loading scheme and boundary ...

• Durability of Natural Fibre-Reinforced Polymer Composites 

  Mak, Kenneth

  Fibre-reinforced polymers (FRP) are a composite system which may be able to meet the demands of both new and existing infrastructures. Due to its constituents’ environmental impact, natural alternatives are becoming ...

• Field monitoring of pile walls designed to selectively stabilize slow moving landslides in Peace River, Alberta 

  McCall, Sam

  The Peace River region of Alberta, Canada is a highly active landslide area characterized by creeping landslides in weak lacustrine clays and silts. Much of the infrastructure for the region is built upon historical ...

• Distributed Sensing to Assess the Behaviour of Dynamically Loaded Reinforced Concrete Beams 

  Broth, Zachary

  The assessment of reinforced concrete (RC) structures has been inherently limited by the lack of adequate sensing technologies, which can capture both the global and localized behaviour of these complex composite systems. ...

• Developing a Framework for the Reliability Analysis of Water Distribution Systems 

  Paez, Diego

  Being able to quantify the reliability of a water distribution system (WDS) is particularly important for decision makers as it allows to take objective decisions for the benefit of the population served by the system. The ...

• Effect of Chemical and Physical Ageing on the Longevity of Smooth and Textured Geomembranes in Geoenvironmental Applications 

  Morsy, Mohamed

  Degradation of physical and mechanical properties of geomembrane (GMB) base liners in various geoenvironmental applications is investigated. This involved conducting immersion tests to simulate the ageing of GMBs on exposure ...

• Damage Threshold of Near-Cross-Ply and Angle-Ply Tubes Used in Concrete Filled FRP Tubes Loaded in Flexure 

  Lu, Chenxi

  Concrete-filled fibre-reinforced polymer (FRP) tubes (CFFTs) have been studied extensively, but a lingering question remains regarding the vulnerability of the exposed tube to accidental damage or vandalism. In this thesis, ...

• Calculating Strain and Stress in Geomembranes at Gravel Indentations 

  Gad Eldesouky, Hesham

  New methods were developed, validated and applied to calculate strain and stress in geomembrane liners from the local deformed shape imposed by overlying coarse gravel under vertical pressure. Previous strain calculation ...
