Hydrological Modeling of the Upper South Saskatchewan River Basin: Multi-basin Calibration and Gauge De-clustering Analysis
(University of Waterloo, 2009-10-29)This thesis presents a method for calibrating regional scale hydrologic models using the upper South Saskatchewan River watershed as a case study. Regional scale hydrologic models can be very difficult to calibrate due ... -
Hygrothermal Behavior of Interior Basement Insulation
(University of Waterloo, 2007-09-17)An uninsulated basement can contribute a significant fraction of a building’s total heating load: insulating the basement can provide significant energy savings. In addition, the desire of homeowners to maximize usable ... -
The Hygrothermal Performance of Exterior Insulated Wall Systems
(University of Waterloo, 2014-06-23)As energy certification programs and mandatory governmental building codes demand better building energy performance, the development of durable, highly insulated wall systems has become a top priority. Wood framed walls ... -
Hygrothermal Performance of Insulated, Sloped, Wood-Framed Roof Assemblies
(University of Waterloo, 2008-05-23)Roofs are the single enclosure element common to artificial shelters constructed by all cultures in all climate regions. The hygrothermal performance of insulated, sloped, wood-framed roof assemblies has long been of ... -
Hypoxic Methane Oxidation Coupled to Denitrification in a Membrane Biofilm Reactor
(University of Waterloo, 2020-05-13)Nitrate removal has become a necessity in Canada and around the globe as a means to mitigate harmful effects from nitrogen compounds, such as eutrophication, which pose toxic hazards to both aquatic life as well as human ... -
Identification and Estimation of Greenhouse Gas Reduction Opportunities through the Implementation of CAES in Canada
(University of Waterloo, 2017-10-25)To reduce greenhouse gas emissions, federal and provincial initiatives have pushed for increased renewable energy penetration on Canadian electric grids. However, renewable power sources such as wind and solar power require ... -
Identification and Treatment of Critical Contaminants for Managed Aquifer Recharge (MAR) with Reclaimed Water
(University of Waterloo, 2015-01-22)Residential and employment growth places great pressure on well-based potable water supply and stream-based wastewater treatment systems, which are common in many areas of Canada. To ensure that increased potable water ... -
IDF Trends Study With MSC Weather Data Using Regression Analysis in Ontario
(University of Waterloo, 2014-09-26)The Ministry of Transportation (MTO) uses Intensity Duration Frequency (IDF) information that was developed with Environment Canada weather information up to 1989 for various infrastructure designs. The IDF curves needed ... -
Impact Assessment of Construction Supply Chain Risk Changes on Project Time and Cost
(University of Waterloo, 2017-09-11)The supply chain plays a key role in the construction industry. The importance of the Construction Supply Chain (CSC) is not less than that of the onsite construction phases. There are many risk factors that influence ... -
Impact of Anaerobic Biofilm Formation on Sorption Characteristics of Powdered Activated Carbon
(University of Waterloo, 2021-07-23)Subsurface contamination by petroleum hydrocarbons (PHCs) results from the leakage of petroleum products during extraction, processing or transport. It has been documented that activated carbon (AC) can effectively sorb ... -
Impact of Biofilter Backwashing on the Biofiltration / Ultrafiltration Process
(University of Waterloo, 2015-09-01)The use of ultrafiltration membrane technology for drinking water treatment has seen a marked increase in the past few decades, however, membrane fouling remains the top technological hurdle in the way of its widespread ... -
Impact of Biological Nutrient Removal Process Operating and Design Conditions on the Removal of Micropollutants from Wastewater
(University of Waterloo, 2015-02-11)The efficacy of three different wastewater treatment configurations, conventional activated sludge (CAS), nitrifying activated sludge (NAS) and biological nutrient removal (BNR) for removal of selected micropollutants from ... -
