High Performance Window Systems and their Effect on Perimeter Space Commercial Building Energy Performance
(University of Waterloo, 2010-09-29)In the quest for improving building energy efficiency raising the level of performance of the building enclosure has become critical. As the thermal performance of the building enclosure improves so does the overall energy ... -
High Resolution Investigation of Thermal Spatial Variability of Two Cobble Bed Rivers, and the Correlation to Salmonid Spawning Preferences
(University of Waterloo, 2016-01-22)This thesis introduces and demonstrates the application of a recently designed mobile streambed temperature measurement system. The apparatus, called the High Resolution Temperature Mapping Device (henceforth HI-RES TMD) ... -
High-precision Sediment Tracking for Characterization of Sediment Transport of a Rural Stream in Southern Ontario Conditioned by Glacial Legacy Deposits
(University of Waterloo, 2019-09-30)Semi-alluvial rivers are common in Southern Ontario and are characterized by sections of exposed highly consolidated glacial till and other sections of mobile sediment. Such rivers are typically characterized by a series ... -
A High-Resolution Hydrodynamic Investigation of Brown Trout (Salmo trutta) and Rainbow Trout (Oncorhynchus mykiss) Redds
(University of Waterloo, 2009-04-28)High-resolution velocity measurements were undertaken over a series of redds and riffles on a gravel-bed stream to quantify the hydrodynamics preferred by spawning brown trout (Salmo trutta) and rainbow trout (Oncorhynchus ... -
High-resolution spatial and temporal sensitivity of river hydrodynamics: Implications for walleye (Sander vitreus) and lake sturgeon (Acipenser fulvescens) spawning habitat use in a large regulated river
(University of Waterloo, 2014-08-25)A reach-scale, high-resolution investigation of the spatial and temporal characteristics and sensitivities of hydrodynamic metrics on a large, low-relief, hydroelectrically regulated river in northwestern Ontario was ... -
Hotspots for Vessel-to-Vessel and Vessel-to-Fix Object Accidents Along the Great Lakes Seaway
(University of Waterloo, 2016-01-14)This research focuses on the freight vessel accidents occurring on the Great Lakes Seaway (GLS) extending from Rimouski (on the St. Lawrence) to Sault Ste. Marie (connecting Lake Huron to Lake Superior). Over the past ... -
How Large Immobile Particles Impact Sediment Transport and Bed Morphology in Gravel Bed Rivers
(University of Waterloo, 2019-05-29)Large particles can be deposited in natural stream channels as a result of failed erosion protection measures or geological deposits. The impacts these large particles have on the natural systems have been studied, however ... -
A hybrid Bayesian network model for predicting delays in train operations
(Elsevier, 2019-01)We present a Bayesian network-(BN) based train delay prediction model to tackle the complexity and dependency nature of train operations. Three different BN schemes, namely, heuristic hill-climbing, primitive linear and ... -
Hybrid Time and Time-Frequency Blind Source Separation Towards Ambient System Identi cation of Structures
(University of Waterloo, 2010-08-24)Blind source separation methods such as independent component analysis (ICA) and second order blind identification (SOBI) have shown considerable potential in the area of ambient vibration system identification. The objective ... -
Hydraulic Performance of the Seepage Collection Ditches at the Albian Sands Muskeg River Mine
(University of Waterloo, 2006)The tailings pond at the Muskeg River Mine is a large structure with a 11 km-long ring dyke that contains process affected water (PAW) and tailings sand. The dyke is made of permeable tailings sand and therefore it is ... -
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 ... -
The Hydrodynamics of Pool-Riffle Sequences with Changing Bedform Length
(University of Waterloo, 2011-08-23)Previous research has demonstrated that pool-riffle bedforms play a critical role in channel stability and ecosystem health in many natural gravel-bed channels. Although the bedform length is known to scale with channel ... -
Hydrologic Change Detection Modelling Methods for Disturbed Forested Watersheds
(University of Waterloo, 2023-01-02)Decades of paired catchment studies have provided insights on how forests regulate water redistribution following vegetation disturbances such as logging and wildfire. In these settings, changes in runoff characteristics ... -
Hydrologic Validation of Real-Time Weather Radar VPR Correction Methods
(University of Waterloo, 2007-01-05)Weather radar has long been recognized as a potentially powerful tool for hydrological modelling. A single radar station is able to provide detailed precipitation information over entire watersheds. The operational use of ... -
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 ... -
