Mitigation of Climate Change Impacts on Runway Friction Kuujjuaq Airport
(University of Waterloo, 2014-04-17)In response to global climate change, Transport Canada has initiated a Climate Change Adaptation Study in order to provide an opportunity to improve knowledge of the impacts of climate change on transportation infrastructure ... -
A Model for Automated Construction Materials Tracking
(University of Waterloo, 2009-01-16)Materials management is a critical factor in construction project performance, particularly in the industrial sector. Research has shown that construction materials and installed equipment may constitute more than 50% of ... -
A Model for Implementing an Automated Change Management Process for Construction Mega-projects
(University of Waterloo, 2014-11-21)This thesis develops a model for implementing and continuously improving the automated change management process for construction megaprojects. Changes are inevitable in megaprojects. Their negative impact along with the ... -
Modeling Nutrient Legacies and Time Lags in Agricultural Landscapes: A Midwestern Case Study
(University of Waterloo, 2019-05-21)Land-use change and agricultural intensification have increased food production but at the cost of polluting surface and groundwater. Best management practices implemented to improve water quality have met with limited ... -
Modeling Safety Performance at Grade Crossing using Microscopic Simulation
(University of Waterloo, 2010-09-27)The analysis of grade crossing safety has long focused on vehicle-train crashes using statistical models based on crash data. The potential crashes generated by vehicle-vehicle rear-end conflicts have often been ignored. ... -
Modeling the Impact of Automated Materials Locating and Tracking Technology on the Construction Supply Network
(University of Waterloo, 2009-08-24)Ineffective materials and equipment management continues to be a leading cause of poor performance on construction projects today. Many of the problems arise as a result of the inability to convey information pertaining ... -
Modeling the Modal Shift towards a More Sustainable Transport by Stated Preference in Riyadh, Saudi Arabia
(MDPI, 2021-01-01)The need to gain a comprehensive understanding of road travelers’ choice of mode and their perceptions of using sustainable urban mobility modes have evolved to shape the form of future transport planning and policymaking. ... -
Modeling the Transportation of Select Trace Organic Contaminants from Source to Ecosystem in the Grand River
(University of Waterloo, 2021-06-02)Trace organic contaminants (TOrC) have been observed in waters downstream of wastewater treatment plants (WWTP) in the Grand River in southern Ontario, Canada. These contaminants have been correlated with adverse impacts ... -
Modeling Volatile Organic Sulfur Compounds In Anaerobic Digestion
(University of Waterloo, 2010-07-19)Anaerobic digestion is a common process for treatment of wastewater sludge from municipal sewage systems. Volatile sulfur compounds, including volatile organic sulfur compounds (VOSCs) and hydrogen sulfide, have been ... -
Modelling Fatigue Deterioration and Retrofitting in Bridge Management Systems
(University of Waterloo, 2016-02-11)Similar to any other structure exposed to the elements, bridges deteriorate and degrade over time. This deterioration can result in costly maintenance and repair if it is addressed properly or damage and even loss of life ... -
Modelling Temporal and Spatial Transportation of Pharmaceuticals, Personal Care Products, and Endocrine Disrupting Compounds in a Canadian Watershed
(University of Waterloo, 2011-08-16)Temporal and spatial concentrations of several pharmaceuticals and personal care products (PPCPs), and endocrine disrupting compounds (EDCs) are predicted in the Grand River watershed using a novel version of the PhATE ... -
Modelling Tile Drains Under Present and Future Climate Conditions
(University of Waterloo, 2008-12-19)Modelling the impact of climate change on the water from agricultural areas on a regional scale over a 40 year time period is the subject of this thesis. The Grand River watershed spans approximately 290 km with an area ... -
Modelling, Simulation and Control of Signalized Intersections under Adverse Weather Conditions
(University of Waterloo, 2016-04-28)Adverse winter weather has always been a cause of traffic congestion and road collisions. To mitigate the negative impacts of winter weather, transportation agencies have been introducing weather responsive traffic management ... -
