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
(University of Waterloo, 2010-05-18)Pavements encompass a significant component of the total civil infrastructure investment. In Ontario, the Ministry of Transportation (MTO) is responsible for the maintenance and construction of approximately 39,000 ... -
Improving Airport Runway Braking Analysis through Innovative Modeling
(University of Waterloo, 2014-07-21)Landing excursion accidents have become a major concern over recent decades regarding airline and airport safety. Available runway friction has a significant impact on aircraft landing performance. This is especially noted ... -
Improving Durability of Asphalt Mixes Produced With Reclaimed Asphalt Pavement (RAP) by Enhancing Binder Blending
(University of Waterloo, 2019-04-30)Reclaimed Asphalt Pavement (RAP) has been favoured over virgin materials in the light of the unstable cost of virgin asphalt binders, shortage of quality aggregates, and compelling need to preserve the environment and ... -
Improving hydrological process representation in lake and forest dominated watersheds
(University of Waterloo, 2022-07-15)Hydrological models are simplified representations of the natural surface water dynamic system. This thesis focuses on improving these representations to make them more realistic and thus more appropriate tools to simulate ... -
Improving leach bed reactor design for medium-chain fatty acid production from food waste at room-temperature.
(University of Waterloo, 2023-02-10)Food waste treatment is an urgent problem which if addressed can make substantial reductions in global greenhouse gas emissions while recovering energy, nutrients, and valuable biomolecules. While anaerobic digestion has ... -
Improving Predictive Models for Road Safety Screening: Cost-Benefit Data Analytics and Deep Generative Models
(University of Waterloo, 2023-04-17)The process of identifying the sites (e.g., road segments, intersections) within a road network that are most in need of detailed safety audits and interventions with the most potential for improvement is known as road ... -
Improving the Fiscal Transparency and Sustainability of Public-Sector Transportation Infrastructure
(University of Waterloo, 2017-08-25)Public-sector infrastructure funding is a complex and often unclear process. Cities operate most efficiently if there is an adequately-funded transportation network with which residents and visitors can easily travel from ... -
Improving the Understanding of Factors Influencing Cryptosporidium Removals Reported for Granular Media Filtration
(University of Waterloo, 2016-01-13)Cryptosporidium is an important waterborne protozoan pathogen which has been implicated in several large gastrointestinal disease outbreaks attributable to inadequate treatment of drinking water. Unfortunately, Cryptosporidium ... -
In-situ chemical oxidation of chlorendic acid by persulfate: Elucidation of the roles of adsorption and oxidation on chlorendic acid removal
(Elsevier, 2019-10-15)The oxidation of chlorendic acid (CA), a polychlorinated recalcitrant contaminant, by heat-, mineral-, and base-activated persulfate was investigated. In pH 3–12 homogeneous (i.e., solid-free) solutions, CA was oxidized ... -
Incorporating Pavement Sustainability into Municiple Best Practices
