Numerical considerations for the simulation of proppant transport through fractures
(Elsevier, 2019-09)Injection of a proppant slurry (fluid mixed with granular material) into a reservoir to keep fractures open is a common procedure in hydraulic fracturing treatments. This article presents the numerical methodology for ... -
Assessment of Regional Flood Frequency Analysis Frameworks for Canada
(University of Waterloo, 2020-01-10)Floods are a devastating natural disaster causing economic loss and even threatening human lives. A better understanding of floods can lead to improved design of flood mitigation measures. The Natural Sciences and Engineering ... -
Regional Frequency Analysis Estimates of Extreme Rainfall Events under Climate Change
(University of Waterloo, 2020-01-09)Extreme rainfall events have a long history of causing large economic damages in urban areas and even loss of human life. Reliable estimates of extreme rainfall intensities for different rainfall durations are essential ... -
Impacts of Climate Change on Canadian Airport Pavements
(University of Waterloo, 2019-12-20)Greenhouse gasses (GHG) emitted by the burning of fossil fuels and supplementary anthropogenic activities are on the rise since the industrial revolution. The world is becoming warmer and more polluted with such gases, ... -
Hydraulic Road Binder (HRB) and Its Use for Subgrade Stabilization in Ontario, Canada
(University of Waterloo, 2019-12-18)The term “subgrade” refers to the in-situ material composed of natural soil located underneath the pavement structural layers. The quality of natural subgrade is highly influenced by soil type, moisture content, and organic ... -
Typologies of Nitrogen Surplus Across Continental US: Shifting Hotspots and Dominant Controls
(University of Waterloo, 2019-12-17)Flows of reactive nitrogen (N) have significantly increased over the last century, corresponding to increases in the global population. The pressures on the N cycle include human waste, fossil fuel combustion as well as ... -
Work Zone Safety Assessment and Throughput Analysis for High Volume Highways Using Random Parameter Models
(University of Waterloo, 2019-12-12)Highways and freeways could be considered the most important transportation infrastructure in North America; these vital routes are necessary for the efficient haulage of huge amounts of goods and services. Several factors ... -
Estimates of gridded relative changes in 24-h extreme rainfall intensities based on pooled frequency analysis
(Elsevier, 2019-10)The potential effect of climate change needs to be considered in urban infrastructure design and risk assessment to improve reliability. The present study proposes a methodology for obtaining grid-scale relative changes ... -
Automatic feature selection and weighting for the formation of homogeneous groups for regional IDF estimation
(Elsevier, 2019-08)The intensity-duration frequency (IDF) curve has been used as an effective tool to quantify the risk associated with the impact of extreme rainfall on civil infrastructure. However, recent changes in the rainfall climatology ... -
Bedload sediment transport regimes of urban gravel-bed rivers under different management scenarios
(University of Waterloo, 2019-12-09)Watershed urbanization profoundly alters the hydrologic characteristics of urban rivers compared to their rural counterparts. This change in hydrologic conditions in combination with alterations to the sediment supply ... -
Application of a Hydrological Model for Predicting River Ice Breakup
(University of Waterloo, 2019-12-06)In cold regions, the breakup of river ice can be a significant event, resulting in flooding and damage to communities. Given the severity of such events, it is desirable to be able to predict the timing and severity of ... -
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 ... -
Reduction of chlorendic acid by zero-valent iron: Kinetics, products, and pathways
(Elsevier, 2020-02-15)Chlorendic acid (CA) is a recalcitrant groundwater contaminant for which an effective treatment technology does not currently exist. In this study, a series of batch experiments were conducted to investigate the treatment ... -
Effects of column imperfections on capacity of steel frames in variable loading
(Journal of Constructional Steel Research, 2019-11-15)The presence of column initial imperfections in a steel frame can increase deflections and decrease its load carrying capacity. A method is proposed for evaluating the lateral stiffness, inter-storey displacement and ... -
Shear deformation effects on stability of unbraced steel frames in variable loading
(Journal of Constructional Steel Research, 2019-11-11)The generalized lateral stiffness equation of a semi-rigidly connected frame with accounting for shear deformation is derived in this paper. The lateral stiffness equation can be used to determine the critical loads of ... -
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, ... -
