Influence of Soil Parameters on Local Pier Scour Depth
(University of Waterloo, 2021-12-15)Bridge scour is a phenomenon where erosion of the sediment bed surrounding bridge foundation occurs due to fluid forces arising from currents, waves, and turbulence. Scour around foundation components such as piers, piles ... -
Informing the practice of ground heat exchanger design through numerical simulations
(University of Waterloo, 2013-02-22)Closed-loop ground source heat pumps (GSHPs) are used to transfer thermal energy between the subsurface and conditioned spaces for heating and cooling applications. A basic GSHP is composed of a ground heat exchanger (GHX), ... -
Infrastructure Asset Management Readiness Assessment of Ontario Municipal Water Utilities
(University of Waterloo, 2020-02-26)The safety and quality of services provided by municipal water utilities depend on sound water and wastewater infrastructure. Nevertheless, according to the 2016 Canadian Infrastructure Report Card, about 12% of this ... -
Initial Biodegradation Potential of Microcystin-LR by Biofilters Experiencing Sudden Cyanobacterial Blooms in Drinking Water Treatment
(University of Waterloo, 2018-09-20)Cyanobacterial blooms have become a major cause of drinking water problems because certain metabolites from cyanobacteria are toxic to human health. Microcystin-LR (MC-LR) is one of the most commonly detected cyanotoxins. ... -
Innovative Evaluation of Crumb Rubber Asphalt and Recycled Asphalt Pavement
(University of Waterloo, 2014-12-02)Recycling asphalt pavement is consistent with the concept of sustainability and when engineered properly, it can potentially provide a more cost-effective alternative to conventional road practices. In 2011, the Centre for ... -
INNOVATIVE NONDESTRUCTIVE TESTING (NDT) FOR CONDITION ASSESSMNET OF LONGITUDINAL JOINTS IN ASPHALT PAVEMENTS
(University of Waterloo, 2007-05-22)The failure of longitudinal construction joints is one of the critical factors causing accelerated pavement deterioration. Poor-quality longitudinal construction joints are often characterized by a difference in elevation ... -
Innovative Shear Connections for the Accelerated Construction of Composite Bridges
(University of Waterloo, 2013-06-13)Accelerated bridge construction methods are being progressively used to construct and replace bridges in North America. Unlike traditional bridge construction methods, accelerated bridge construction methods allow bridges ... -
Instrumentation and Overall Evaluation of Perpetual and Conventional Flexible Pavement Designs
(University of Waterloo, 2009-08-28)The perpetual structural pavement design is currently being explored for usage in Canada and worldwide. This thick structural design can provide many potential benefits but it also has associated costs. Cold Canadian winters ... -
Integrated Asset Management Framework and Model for Water Distribution Networks
(University of Waterloo, 2020-05-28)The Canadian Infrastructure Report Card (2012) estimates the replacement value of water assets to be $362 billion. Water distribution and wastewater collection networks have been in service for more than a century in the ... -
An Integrated Behavior and Demand-Oriented Methodology for Quality of Service Evaluation of Bicycle Infrastructure
(University of Waterloo, 2023-02-13)Cycling is a viable mode of transport, and its mode share is consistently growing in many parts of the globe. However, many existing infrastructures still lack the safety and convenience that cyclists of all levels of ... -
Integrated Daily Windows and But-For Analyses for Accurate Schedule Forensics in Construction Projects
(University of Waterloo, 2021-10-04)Construction projects usually operate in dynamic multi-party constrained environments that frequently cause schedule delays and cost overruns and lead to disputes among parties. To mitigate such disputes and fairly apportion ... -
An Integrated Design Approach for Improving Drinking Water Ozone Disinfection Treatment Based on Computational Fluid Dynamics
(University of Waterloo, 2007-01-22)Ozonation is currently considered as one of the most effective microbial disinfection technologies due to its powerful disinfection capacity and reduction in levels of chlorinated disinfection by-products (DBP). However, ... -
Integrated Performance Analysis and Optimum Fund Allocation for Capital Renewal of Healthcare Facilities
