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 ... -
Surface wave and storm surge prediction during Hurricane Sandy
(2016-09-21)Hurricane Sandy was the largest storm on historical record in the Atlantic Ocean basin with extensive coastal damage caused by large waves and high storm surge. The primary objectives of this thesis are to compare and ... -
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) ... -
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. ... -
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 ... -
Thermal Effects on Monitoring and Performance of Reinforced Concrete Structures
(2012-10-31)Much of North America’s reinforced concrete infrastructure is reaching the end of its service life and careful inspection and assessment is required to ensure the appropriate capacity is maintained in these structures. The ... -
Thermal Properties of Green Roofs in Cold Climates
(2007-09-26)Green roofs have, in the past 15 years or so, gained increasing acceptance as a means of replacing or offsetting the lost of green space due to urban development and urban sprawl. Green roof systems can provide numerous ... -
Three Dimensional Numerical Analysis of Static Pipe Bursting
(2013-02-27)During pipe bursting, a cone shaped expander is pulled through an existing pipe, breaking it, enlarging the cavity, and pulling a replacement pipe into place. The expansion of the soil cavity and axial movements of the ... -
Three-Dimensional Dynamics of Nonlinear Internal Waves
(2012-12-14)The three-dimensional (3D) baroclinic response of Cayuga Lake to surface wind forcing was investigated using the fully nonhydrostatic MITgcm. The model was validated against observed temperature data using a hydrostatic ... -
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 ... -
Three-Dimensional Modelling of Lake Ontairo Hydrodynamics Near Port Hope and in the Upper St Lawrence River
(2013-07-18)The Ontario Clean Water Act (2006) mandated that eight and two municipal drinking water intakes in the Cataraqui Region Conservation Authority (CRCA) and the Ganaraska River Source Protection Agency (GRSPA) jurisdictions ... -
Three-Dimensional Nonlinear Analysis of Deep-Corrugated Steel Culverts
(2011-04-26)Deep-corrugated steel culverts (with a corrugation wavelength of 400mm and amplitude of 150mm) can be used as an effective alternative for short-span bridges. Current design methods are typically based on two-dimensional ... -
Three-Dimensional Simulation of Water Quality in a Wastewater Stabilization Pond
Wastewater stabilization ponds (WSP) are effective secondary or tertiary treatment systems, however simple water quality models that assume the ponds behave as either completely stirred tank reactors (CSTR) or plug flow ... -
Time and Patterns of Development of Dunes Subjected to Sudden Changes in Flow Depth
(2007-09-26)In unsteady flows, dune dimensions may vary considerably from fully-developed dimensions produced from a flat bed under a steady and uniform flow. Specifically, dune height and length are observed to lag discharge when ... -
Time dependent response of pulled-in-place HDPE pipes
(2008-06-19)Horizontal directional drilling is increasingly used to install pipes without costs and disruptions associated with conventional ‘cut and cover’ installations. This technique, which was developed by industrial innovators, ... -
Time-Dependent Performance of Column-Supported Embankments Involving Viscous Reinforcement and Prefabricated Vertical Drains
(2015-06-02)A fully 3D coupled finite element (FE) analysis is performed to examine the performance of four sections of a full-scale embankment on soft soils. The proposed FE model successfully captures the behaviour of full scale ... -
Tracing Flows of Water, Energy, and Waste Through an Idealized Water Distribution Network Using an Urban Metabolism Based Approach
(2015-09-03)‘Urban Metabolism’ (UM) is a well-established concept based on the parallels between the metabolisms’ of ecosystems and cities. These parallels consist of the intake, storage, and transformation of materials and energy, ... -
Transient High-Temperature Prestress Relaxation of Unbonded Prestressing Tendons for use in Concrete Slabs
(2009-09-26)Unbonded post-tensioned (UPT) flat plate concrete slabs have seen widespread use in multi-storey office and condominium buildings since the 1960s. The popularity of these systems can be attributed to various economic and ... -
The Transport of Heat by Flowing Groundwater in a Discrete Fracture
(2016-05-11)In typical theoretical or experimental studies of heat migration in discrete fractures, conduction and thermal dispersion are commonly neglected from the fracture heat transport equation, assuming heat conduction into ... -
Transport of PBDE, MWCNTS, and BPA (Contaminants of Emerging Concern) Through Modern Landfill Liners
(2016-02-01)Diffusion of three contaminants of emerging concern: (1) polybrominated diphenyl ether (PBDE), (2) multiwall carbon nanotubes (MWCNTs), and (3) bisphenol A (BPA) through high density polyethylene (HDPE) geomembrane (GMB) ...
