(University of Waterloo, 2008-05-21)Nondestructive evaluation of civil structures is of increasing interest to utility owners. Several methods exist to evaluate different properties of concrete, pavement, cemented sands and others. UPVM is the most commonly ... -
A Sediment Budget of an Urban Creek in Toronto
(University of Waterloo, 2014-09-02)Wilket Creek is a second order stream located in Toronto, Ontario. Over the past decade, management efforts have intensified to protect infrastructure including walking paths, bridges, sanitary sewers and private property. ... -
Sediment Transport and Metals Modeling in an Urban Stream - The Don River, Toronto
(University of Waterloo, 2015-09-28)The Don River watershed has been subjected to rapid urbanization over the last few decades. As a result, vast area of built-up land has shifted the watershed’s hydrologic cycle towards lower infiltration and higher runoff ... -
Seismic Fragility Analysis for Structures, Systems, and Components in Nuclear Power Plants
(University of Waterloo, 2017-01-18)Seismic fragility analysis has been widely used to evaluate seismic capacities of structures, systems, and components (SSCs) in nuclear power plants. In the seismic fragility analysis, a single ground motion parameter ... -
Seismic Performance Assessment of Multi-Storey Buildings with Cold Formed Steel Shear Wall Systems
(University of Waterloo, 2007-05-22)Cold-Formed Steel (CFS) is a material used in the fabrication of structural and non-structural elements for the construction of commercial and residential buildings. CFS exhibits several advantages over other construction ... -
Seismic Risk Analysis for Nuclear Energy Facilities
(University of Waterloo, 2015-02-20)Earthquakes are destructive natural disasters that can inflict various levels of damage on engineering structures and lead to other adverse consequences. Accurate seismic risk quantification of critical engineering structures ... -
Selecting Sustainable Point-of-Use and Point-of-Entry Drinking Water Treatment: A Decision Support System
(University of Waterloo, 2011-08-10)Point-of-use (POU) and point-of-entry (POE) water treatment are forms of decentralized water treatment that are becoming increasingly sought alternatives for ensuring the safety of drinking water. Although the acceptance ... -
Semi-analytical methods for simulating the groundwater-surface water interface
(University of Waterloo, 2014-08-26)Groundwater-surface water interaction is a key component of the hydrologic cycle. This interaction plays a key role in many environmental issues such as the impacts of land use and climate change on water availability and ... -
A Semi-Analytical Particle Tracking Algorithm for Arbitrary Unstructured Grids
(University of Waterloo, 2015-10-30)Semi-analytical particle tracking methods are broadly used in determining advective transport within groundwater flow models. The Pollock method is currently implemented in the USGS model MODPATH as a semi-analytical ... -
Semi-Automated Methods for Measuring Practice Conformance for Capital Projects
(University of Waterloo, 2020-08-06)The goal of this thesis is to explore semi-automated methods for measuring practice conformance for capital projects. Thorough measurement of practice conformance for capital projects typically requires manual audits. ... -
Semi-Automated Microscopic Traffic Flow Simulation Development Using Smart City Data
(University of Waterloo, 2021-08-24)Microscopic traffic simulation models have been widely used by transportation planners and engineers for conducting various road network planning and traffic engineering tasks. Due to data limitations, traffic simulation ... -
