Novel Sensors for Improving Reinforced Concrete Design and Assessment
The rate that reinforced concrete (RC) infrastructure is being constructed around the world continues to increase, placing significant stress on the environment. Thus, it is important that any inefficiencies in RC design ... -
Numerical Modeling of Thermal Enhancement of In Situ Chemical Oxidation (ISCO) and Enhanced In Situ Bioremediation (EISB)
(2014-02-11)A numerical model was utilized to assess the effects of elevated temperature on the application of in situ chemical oxidation (ISCO) and enhanced in situ bioremediation (EISB) for the subsurface remediation of trichloroethene ... -
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 ... -
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 ... -
Numerical Study and Load and Resistance Factor Design (LRFD) Calibration for Reinforced Soil Retaining Walls
(2010-01-29)Load and resistance factor design (LRFD) (often called limit states design (LSD)) has been mandated in the AASHTO Bridge Design Specifications and will be adopted in future editions of Canadian Highway Bridge Design Code ... -
On the Simulation and Prediction of Bed Morphological Adjustments of Equilibrium in Alluvial Meandering Streams
(2009-01-05)This thesis concerns the computation of bed adjustments of equilibrium in alluvial meandering streams. It is assumed that the channel centerlines follow sine-generated curves, the banks are rigid, and the steady-state flow ... -
Operation of Solid Oxide Fuel Cells on Anaerobically Derived Wastewater Treatment Plant Biogas
(2012-09-08)Solid Oxide Fuel Cells (SOFCs) have been researched for operation on anaerobic digester (AD)-derived biogas at wastewater treatment plants (WWTPs). SOFCs can perform well on light hydrocarbon fuels and the use of AD-derived ... -
Out-Of-Plane Bending Of Masonry Walls With Near-Surface-Mounted And Externally-Bonded Corrosion-Resistant Reinforcement
(2010-05-31)Masonry walls subjected to out-of-plane loading, such as in a seismic event, require reinforcement to improve the ductility of the system. In current masonry construction practice, reinforcement is placed internally and ... -
Parallel-to-Grain Withdrawal Resistance of Structural Self-Tapping Screws in Canadian Timber
This thesis investigates the withdrawal capacity of self-tapping screws (STS) inserted parallel-to-grain. An experimental study was conducted with 100 screws tested in total. The experimental program includes two main test ... -
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. ... -
Passive and Naturalized Landfill Leachate Treatment Systems for Source Water Protection
(2011-10-03)Landfill leachate production is an unavoidable by-product of landfilling solid waste. Mitigation of the adverse environmental impacts of landfill leachate is required at all active and closed landfill sites. Since leachate ... -
Pedestrian-Induced Bridge Response: Using a modal response model to predict the vibrations of a bridge when subjected to periodic pedestrian loads
(2010-05-03)The availability and use of new materials and construction techniques are allowing bridges to be built that are longer and more slender to those that have been constructed in the past. This can cause bridges to have lower ... -
Performance and Assessment of Rehabilitated Steel Culverts
(2016-10-25)This thesis explores the effects of rehabilitation on the structural performance of corrugated steel culverts. A full-scale laboratory experiment investigated the effects of grouted slip-liners on the performance of two ... -
Performance of Geomembranes to Contain PCBS, Brine and Reverse-Osmosis Water
Accelerated ageing tests are used to examine the performance of geomembranes in three applications. The thesis examines a broad range of geomembranes produced over a time span of 30 years and highlights the progress made ... -
Performance of Geosynthetic Clay Liners in Cover, Subsurface Barrier, and Basal Liner Applications
(2014-02-28)The use of geosynthetic clay liners (GCLs) as (i) covers for arsenic-rich gold mine tailings and landfills, (ii) subsurface barrier for migration of hydrocarbons in the Arctic, and (iii) basal liner for sewage treatment ... -
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 ... -
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 ... -
Performance of Trenchless Rehabilitations for Culvert, Sewer, and Maintenance Hole Structures
Deterioration and rehabilitation impacts on buried infrastructure were explored using experimental methods. Deterioration studies included the effects of erosion voids (in the immediate backfill) on steel and reinforced ... -
A Phenomenological Model for the Planimetric Evolution of Meandering Rivers and Related Database
This work concerns the planimetric evolution of free meandering rivers, whose associated riverbank erosion and channel changes notoriously pose a hazard to infrastructure within their vicinity as well as affect the health ... -
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 ...
