Efficient treatment of climate data uncertainty in ensemble Kalman filter (EnKF) based on an existing historical climate ensemble dataset
(Elsevier, 2019-01)Successful data assimilation depends on the accurate estimation of forcing data uncertainty. Forcing data uncertainty is typically estimated based on statistical error models. In practice, the hyper-parameters of statistical ... -
Turbulence structures in isolated pool-riffle units
(University of Waterloo, 2019-01-28)The macroscale morphology of a river has significant effects on sediment transport, flow pattern, bed stability, and ecosystem function. Pools and riffles, which are respectively the deeper and shallower parts of the bed, ... -
Three Dimensional Digital Image Correlation for Dynamic Measurements
(University of Waterloo, 2019-01-25)Structural inspections have traditionally been completed by inspectors using simple tools to determine the health of a structure. The limitations using these techniques led to the development of quantitative sensors such ... -
Pressure Sensor Placement for Leak Diagnosis under Demand Uncertainty in Water Distribution Systems
(University of Waterloo, 2019-01-24)Leakages in concealed pipes in urban water distribution systems (WDS) can cause losses of up to 25% of potable water supply in municipalities. These losses are not only a tremendous waste of water but also the energy spent ... -
Construction Site-Layout Optimization Considering Workers' Behaviors Around Site Obstacles, Using Agent-Based Simulation
(University of Waterloo, 2019-01-24)The majority of construction projects, especially large ones, experience time delays, cost overruns, productivity loss, and/or accidents. This is particularly so in case of congested and disorganized sites that contain ... -
Life cycle sustainability assessment of asset management plans for municipal wastewater systems
(University of Waterloo, 2019-01-24)Municipal governments have the responsibility to provide safe drinking water and handle polluted water to protect their citizen’s health and safety. Maintaining water infrastructure systems, including wastewater collection ... -
Bond Behaviour of Concrete Beams with Glass Fibre Reinforced Polymer Bars Under Fatigue Loading
(University of Waterloo, 2019-01-17)Since the 1980s and after the aerospace industries faced several periods of economic difficulty, the companies that produced fibre-reinforced polymers (FRPs) started to introduce them as new materials for construction ... -
Predicting the Removal of Micropollutants in Lake Ontario and Grand River using Ozonation
(University of Waterloo, 2019-01-15)Micropollutants occur at low concentrations (µg/L to ng/L), can have a range of environmental and health effects, and can enter surface water through run-off from fields and wastewater discharge. Surface water is used for ... -
Fine Sediment Contributions to Cyanobacterial Growth: Potential Threats to Drinking Water Reservoirs
(University of Waterloo, 2019-01-14)In the drinking water industry, the transport and release of nutrients such as phosphorus (P) to the water column is largely overlooked in reservoir management. Phosphorus is considered the key limiting nutrient for algal ... -
Framework for Scheduling, Controlling, and Delivery Planning for Scattered Repetitive Infrastructure Rehabilitation Projects
(University of Waterloo, 2019-01-07)Public-Sector organizations such as School Boards and Universities are struggling to keep their aging facilities operational and reducing the large backlog in infrastructure renewal needs. The cost to bring school and ... -
DEVELOPMENT OF HIGH MODULUS ASPHALT CONCRETE MIX DESIGN TECHNOLOGY FOR USE ON ONTARIO’S HIGHWAYS
(University of Waterloo, 2019-01-07)Asphalt pavement is subjected to external loads including mechanical loading induced by traffic and thermal loading induced by thermal variations. The last decades have witnessed a significant rise in number of heavy ... -
Water Main Life Cycle Analysis Framework for the Economic Evaluation of OM&R (Operation, Maintenance and Renovation) Strategies.
(University of Waterloo, 2018-12-21)Municipal water systems deliver potable water to residents, businesses, and industries. The potable water infrastructure was mostly laid in 1880-1970`s in North America. Being a buried asset i.e. an out of sight network, ... -
Fermentation of Food Waste in a Leach Bed Reactor- Effects of pH and Inoculum to Substrate Ratio
(University of Waterloo, 2018-12-19)A more sustainable method for the treatment of accumulated food waste, instead of landfilling, is in urgently need. Fermentation is one of the most promising waste-to-energy technologies for energy recovery from food waste. ... -
Statistical Sample Size Determination Methods for Inspections of Engineering Systems
(University of Waterloo, 2018-12-18)A statistical sample size determination (SSD) method is designed for the maintenance of engineering components of similar structure within an overall system. The maintenance problem is defined as a sequential decision-making ... -
A non-local plasticity model of stimulated volume evolution during hydraulic fracturing
(Elsevier, 2018-10-02)Hydraulic fracturing in naturally fractured rocks often leads to the creation of a stimulated zone in which the target rock formation is deformed and fractured by the reactivation and shear dilation of natural fractures ... -
A Micromechanical Study of Undrained Granular Media Using Fluid-coupled Discrete Numerical Simulations
(University of Waterloo, 2018-12-06)Engineering behavior of saturated granular materials under rapid loading as during earthquakes is reasonably well explored empirically. Presently, theoretical models developed within concepts of classical soil mechanics ... -
Development of a Ridged Slip-Resistant Connection for Modular Aluminum Bridge Deck Applications
(University of Waterloo, 2018-12-04)Aluminum is a lightweight material that possesses excellent corrosion resistance and has been shown to be an attractive alternative to steel and concrete for the construction and rehabilitation of bridge structures. It ... -
Realistic expectations for the treatment of FMGP residuals by chemical oxidants
(Elsevier, 2018-12-01)Methods to remediate soil and groundwater contamination at former manufactured gas plant (FMGP) sites are scarce. The objective of this study was to investigate the ability of two chemical oxidants (persulfate and permanganate) ... -
Assessing the Utility of Hydrologic Model Diagnostics for Decision Support
(University of Waterloo, 2018-11-27)Theoretical, computational and experimental advances have led to easier access to more complex and robust hydrologic models. These hydrologic models may be used to support decision making by water managers and stakeholders. ... -
