Impact of Winter Road Conditions on Highway Speed and Volume
(University of Waterloo, 2014-01-29)Several past studies have attempted to quantify the impact of winter weather conditions on highway mobility in terms of traffic volume, speed, and capacity. While consistent in their general findings, these studies have ... -
Impacts of Climate Change on Canadian Airport Pavements
(University of Waterloo, 2019-12-20)Greenhouse gasses (GHG) emitted by the burning of fossil fuels and supplementary anthropogenic activities are on the rise since the industrial revolution. The world is becoming warmer and more polluted with such gases, ... -
Impacts of Hydromodification and Sediment Supply Alterations on Bedload Transport and Bed Morphology in Urbanizing Gravel-bed Rivers
(University of Waterloo, 2017-08-18)Urbanization is known to change the hydrologic and sediment supply regimes of rivers, causing more frequent, flashier flood events (hydromodification) and a reduction and redistribution of sediment sources. Presently, the ... -
Impacts of Psychrophilic Conditions on Anaerobic Membrane Bioreactors Treating Municipal Wastewater
(University of Waterloo, 2019-05-27)Three 5 L AnMBRs that incorporated submerged ZeeWeed® hollow fibre PVDF membranes with a nominal pore size of 0.04 µm and a nominal membrane surface area of 0.047 m2 were employed. The AnMBRs were operated at a solids ... -
The Impacts of Stormwater Management on Hydromodification and Bedload Sediment Transport in a Gravel-bed Stream
(University of Waterloo, 2017-09-27)Global trends of increasing urbanization have led many researchers to attempt to quantify the resulting impacts on channel morphology and on the ecological health of urban channels. Overall, there has been a lack of research ... -
Impacts of the Introduction of an Express Transit Service in Waterloo Region
(University of Waterloo, 2008-01-08)For more than a century, public transportation has played a significant role in society. Transit agencies, like other service industries, are intent on improving their quality of service so as to increase transit ridership ... -
Implications of Lateral Flow Generation on Land-Surface Scheme Fluxes
(University of Waterloo, 2002)This thesis details the development and calibration of a model created by coupling a land surface simulation model named CLASS with a hydrologic model named WATFLOOD. The resulting model, known as WatCLASS, is able to ... -
Improved Data Uncertainty Handling in Hydrologic Modeling and Forecasting Applications
(University of Waterloo, 2019-03-15)In hydrologic modeling and forecasting applications, many steps are needed. The steps that are relevant to this thesis include watershed discretization, model calibration, and data assimilation. Watershed discretization ... -
An Improved Framework for Watershed Discretization and Model Calibration: Application to the Great Lakes Basin
(University of Waterloo, 2015-01-20)Large-scale (~103–106 km2) physically-based distributed hydrological models have been used increasingly, due to advances in computational capabilities and data availability, in a variety of water and environmental resources ... -
Improved Interflow and Infiltration Algorithms for Distributed Hydrological Models
(University of Waterloo, 2010-09-28)The shallow subsurface controls the partitioning of available energy between sensible and latent heat of the land surface, and the partitioning of available water among evaporation, infiltration, and runoff. It is a key ... -
Improved Numerical Methods for Distributed Hydrological Models
(University of Waterloo, 2010-01-21)Distributed hydrological models have been used for decades to calculate and predict the movement of water and energy within watersheds. These models have evolved from relatively simple empirical applications into complex ... -
Improved Schedule Analysis Considering Rework Impact and Optimum Delay Mitigation
(University of Waterloo, 2009-12-11)Rework has been a primary cause of cost and schedule overruns in the construction of heavy industrial projects such as those related to oil and gas. It has been reported that the direct cost of rework is about 5% of total ... -
An Improved Static Seismic Design Method for Podium Structures with Vertical Irregularity of Mass and Stiffness
(University of Waterloo, 2021-01-12)Owing to potentially reduced costs and faster project timelines, North American designers are increasingly opting for novel structural systems that are not well-addressed by the current model codes. Specifically, mid-rise ... -
Improved Streamflow Simulation through Ensemble and Stochastic Conceptual Data-driven Approaches
(University of Waterloo, 2022-08-18)To better understand the complexities of water movement on earth, hydrologists have developed process-based hydrological models (HMs) and data-driven models (DDMs), both of which have been applied to a host of water resources ... -
Improvement to Highway Safety through Network Level Friction Testing and Cost Effective Pavement Maintenance
