Heat Migration and Solute Transport in a Discrete Fracture
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 ... -
Heated Biofilm Growth in a Planar Fracture for Reduction of Hydraulic Aperture
(2011-08-10)The objective of this study was to examine the effect of heat on the growth of a biofilm in a parallel glass plate fracture table. Groundwater was collected from a limestone aquifer and amended with a nutrient mixture ... -
Humanitarian engineering in the engineering curriculum
(2008-08-27)There are many opportunities to use engineering skills to improve the conditions for mar-ginalized communities, but our current engineering education praxis does not instruct on how engineering can be a force for human ... -
Humanitarian Engineering: Addressing the global influence of applied technology in engineering education
(2008-04-29)The immensity of the social and (natural) environmental impacts that technologies have in today’s global context challenges the existing engineering education curricula. Observational research inspired the notion that the ... -
Hybrid Members Employing FRP Skin Reinforcement for Beams and Cladding Wall Applications
(2009-01-05)This thesis explores two hybrid systems employing a core material reinforced by an external skin, namely, cladding walls composed of polyurethane foam core sandwiched between fibre-reinforced polymer (FRP) skins, and beams ... -
Hydraulic fracture experiments in a frictional material and approximations for maximum allowable mud pressure
(2008-08-07)Directional drilling has become a popular construction method used by municipalities, contractors and engineers alike for the construction of new subsurface pipelines while minimizing impact on the surrounding community. ... -
Hydraulic Performance of Geosynthetic Clay Liners (GCLs) in Containment of Brine and Landfill Applications
The interface transmissivity (θ) and hydraulic conductivity (k) of conventional and multicomponent geosynthetic clay liners (GCLs) were examined for a range of normal stresses (i.e., 10 kPa, 25 kPa, 50 kPa and 150 kPa) ... -
Hydraulic Performance of Geosynthetic Liners in Landfills and Tailings Storage Facilities
(2016-05-02)The effects of holes in a geomembrane on leakage through the base liner of a modern municipal solid waste and mine tailings storage facilities was examined. First, the performance of overlapped seams below a geomembrane ... -
Hydrodynamic Modelling of Lake Ontario
(2008-10-21)The 2006 Clean Water Act requires each municipality to come up with science-based plans to protect the quality and quantity of their drinking water. A literature review concerning applicable processes in Lake Ontario along ... -
Hydrodynamics of a Large and Shallow Back-Barrier Estuarine System and Responses to Long-Term Changes in Geomorphology
(2014-12-19)Coupled hydrodynamic and wave models were used to simulate water levels, currents, waves and salinity transport in the Albemarle-Pamlico Estuarine System (APES), a large shallow back-barrier basin in eastern North Carolina, ... -
Hydrogen Gas Production and Effects During Remediation Using Nano-scale Zero-valent Iron
The objective of this study was to develop an understanding of the potential effects of hydrogen gas (H2) exsolution during nanoscale zero-valent iron (nZVI) groundwater remediation applications. An improved understanding ... -
Identifying downhole fracture characteristics using in-situ fluorescence monitoring : the results and interpretation of a large-scale radially divergent tracer experiment conducted in a dolomite aquifer
(2008-07-16)In several field studies it was concluded that highly transmissive features transmit the majority of solute mass in horizontally-fractured bedrock aquifers. The purpose of this investigation is to develop a new technique ... -
Impulse waves generated by gravitationally-accelerated granular landslides in a large scale flume
(2016-02-01)Landslide-generated impulse waves are a risk to coastal areas near possible sources of large and rapid landslides. A better understanding of the generation of these waves is important for the prediction of the size of these ... -
Incorporating Environmental Impacts into Multi-Objective Optimization of Water Distribution Systems
(2009-08-25)Municipal water distribution system (WDS) expansion is often focused on increasing system capacity with designs that best meet hydraulic requirements at the least cost. Increasing public awareness regarding global warming ... -
Influence of Foundation Stiffness on Reinforced Soil Wall
(2007-11-02)The influence of yielding foundations on the mechanical behaviour of reinforced soil walls including wall deformations and loads (strains) in the reinforcement layers is very complex. Based on a review of the literature, ... -
Innovative Hybrid FRP/STEEL Splice Details for Modular Bridge Expansion Joints
(2011-12-01)Bridge expansion joints are directly subjected to traffic load, and thus prone to premature fatigue failure. Replacement of components such as modular bridge expansion joints is typically done in a staggered schedule to ... -
Interstorey Drift Performance of Timber Beam-Hanger Connections
This thesis is split into two distinct sections. The first describes the design of a testing setup for applying simulated earthquake loads to a timber beam-hanger connection, and the second evaluates the performance of ... -
Intertidal hydrodynamics and basin-scale sediment dynamics in the Minas Basin, Bay of Fundy, and implications for change due to tidal power extraction
(2015-01-12)Minas Basin in the Bay of Fundy has the world’s largest tidal range and exchanges approximately 110 billion tonnes of water twice a day with tidal currents up to 5 ms-1 through Minas Passage, making it an ideal site for ... -
Investigating the effect of algal blooms on water quality in passive wastewater treatment systems
