Checkered Landscapes: Quantifying Dominant Control on Nitrogen Legacies and Time Lags along the River Continuum
(University of Waterloo, 2020-08-20)In agricultural watersheds across the world, decades of commercial fertilizer application and intensive livestock production have led to elevated stream nutrient levels and problems of eutrophication in both inland and ... -
Classification of Construction Projects
(World Academy of Science, 2015-07-01)In order to address construction project requirements and specifications, scholars and practitioners need to establish taxonomy according to a scheme that best fits their need. While existing characterization methods are ... -
Climate Change Projection and Time-varying Multi-dimensional Risk Analysis
(University of Waterloo, 2016-09-20)In recent decades, population growth and global warming consequent to greenhouse gas emissions because of human activities, has changed the atmospheric composition leading to intensifying extreme climate phenomena and ... -
Climate impacts on hydrometric variables in the Mackenzie River Basin
(University of Waterloo, 2008-01-25)The research described in this thesis examines how the hydrologic cycle is affected by climate changes in the Mackenzie River Basin (MRB) in northern Canada. The study focuses on five hydro-meteorological variables; runoff, ... -
Closed Loop Geothermal System Design
(University of Waterloo, 2022-06-17)In contrast to other renewable sources (e.g., wind and solar) that may only be intermittently available throughout a day or year, geothermal resources provide a carbon-free and sustainable source of energy for base-load ... -
A Cloud-Based Architecture for BIM as an Asset for Project Management
(University of Waterloo, 2019-08-12)After more than 30 years of research, better solutions continue to be sought for nuclear power plant decommissioning and radioactive waste management. As some approaches are interesting, improvements are still required in ... -
Coagulant addition for managing sediment-associated phosphorus bioavailability to prevent cyanobacterial blooms in drinking water reservoirs
(University of Waterloo, 2021-08-27)To ensure the uninterrupted supply of adequate amounts of drinking water, many utilities rely on reservoirs for raw (i.e., untreated) water storage prior to treatment. For example, reservoirs are integral to storing water ... -
Combined Strategic-Tactical Planning for Facility Rehabilitation Using System Dynamics and Optimization
(University of Waterloo, 2016-01-25)Rehabilitation programs are essential for efficiently managing large networks of infrastructure assets and sustaining their safety and operability. While numerous studies in the literature have focused on various aspects ... -
Comparative Assessment on Static O-D Synthesis
(University of Waterloo, 2022-08-02)Recognizing the benefits of data and the information it provides to travel demand is pertinent to network planning and design. Technological advances have led the ability to produce large quantities and types of data and ... -
Comparing Cold In-Place Recycling (CIR) and Cold In-Place Recycling with Expanded Asphalt Mixture (CIREAM)
(University of Waterloo, 2015-09-01)Cold Mix Asphalt (CMA) is used in several rehabilitation techniques, which uses 100% Reclaimed Asphalt Pavement (RAP), thus making it a sustainable product in the industry. Using CMA for rehabilitation decreases the energy ... -
Comparing the Safety and Mobility Benefits of Alternative Winter Road Maintenance Standards
(University of Waterloo, 2019-10-24)In countries like Canada, driving conditions can be significantly deteriorated by adverse winter weather conditions, such as ice and snow storms. To reduce the negative effects caused by inclement winter weather conditions, ... -
Comparison between Optimization and Heuristic Methods for Large-Scale Infrastructure Rehabilitation Programs
(University of Waterloo, 2012-09-26)Civil infrastructure systems are the foundation of economic growth and prosperity in all nations. In recent years, infrastructure rehabilitation has been a focus of attention in North America and around the world. A large ... -
Comparison of Condition Evaluation Methods for Flexible Pavement, and Exploration of Ride Quality Assessment through Vibration Frequency Analysis
(University of Waterloo, 2023-12-12)This thesis reviews and compares evaluation standards, distress manifestation manuals, and key performance indices for flexible road asset management across North America. Evaluation of pavement structural and functional ... -
Comparison of Conventional and Advanced Pavement Design Methods with Ontario Case Studies
(University of Waterloo, 2020-12-14)Many methods have been used to effectively design a pavement structure that carries the required traffic loads. In Canada, American Association of State Highway and Transportation Officials 93 (AASHTO 93), Shell Pavement ... -
Comparison of Ontario Pavement Designs Using the AASHTO 1993 Empirical Method and the Mechanistic-Empirical Pavement Design Guide Method
(University of Waterloo, 2013-11-27)The AASHTO 1993 Guide for Design of Pavement Structures is the most widely used pavement design method in both Canada and the United States, and is currently used by the Ministry of Transportation of Ontario (MTO) for both ... -
