Quantifying and Modelling Post-Wildfire Sediment Production in Waterton Lakes National Park
(University of Waterloo, 2021-12-16)High-severity wildfires can increase sediment mobility and erosion rates in burned landscapes which increase the delivery of fine sediment to receiving streams. The downstream propagation of these pyrogenic materials can ... -
Quantifying coniferous subalpine tree transpiration and source water under seasonal and hydrological stress in the Canadian Rocky Mountains, Kananaskis, Alberta
(University of Waterloo, 2019-06-04)Fresh water supplies in mountainous regions are at risk as snow and ice stores continue to decline under rising global temperatures, earlier winter snowmelt and changing climate regimes. Alpine forests are of particular ... -
Quantifying the Influence of Soil Prescriptions on Ecosystem Processes in Reclaimed Forests of Varying Age in a Post-Oil Sands Landscape in the Athabasca Oil Sands Region, Alberta, Canada
(University of Waterloo, 2020-03-03)The Athabasca Oil Sands Region (AOSR) in northern Alberta, Canada contains ~4800 km2 available for surface mining, and as of 2017 ~767 km2 had been disturbed for oil sands operations. The Alberta government requires this ... -
Quantifying the role of shade on microclimate conditions and water use efficiency of a subalpine wetland in the Canadian Rocky Mountains, Kananaskis, Alberta
(University of Waterloo, 2020-01-17)Alpine regions contribute 60 % of annual surface runoff, playing an important role in regulating the global water balance. Many of the world’s major river networks originate from alpine headwater basins, popularizing ... -
Quantifying Variation in Wetland Composition and Configuration for Landscape-Scale Reclamation Planning
(University of Waterloo, 2016-10-06)Widespread loss and degradation of wetland ecosystems resulting from human land use highlights the need for a reclamation strategy (i.e converting developed land back to its original state) that can sustain ecosystem ... -
Quantifying water use and rainfall partitioning of dominant tree species in a post-mined landscape in the Athabasca Oil Sands Region, Alberta
(University of Waterloo, 2020-12-08)Large-scale oil sands mining has caused significant disturbances to forest and wetland ecosystems in the Western Boreal Plains of Northeastern Alberta. Provincial and federal laws mandate restoration of these systems in ... -
Quaternary Geomorphology of the Quebec North Shore, Godbout to Sept-Iles
(University of Waterloo, 2016-09-27)This report presents a summary of the physical properties of surficial deposits, evolution of the landscape and economic aspects of the materials. Surficial geology maps of the Sept-Iles and Cap Chat map sheets, at a scale ... -
RADARSAT-2 Polarimetric Radar Imaging for Lake Ice Mapping
(University of Waterloo, 2017-11-21)Changes in lake ice dates and duration are useful indicators for assessing long-term climate trends and variability in northern countries. Lake ice cover observations are also a valuable data source for predictions with ... -
A Random Forest Based Method for Urban Land Cover Classification using LiDAR Data and Aerial Imagery
(University of Waterloo, 2012-05-23)Urban land cover classification has always been crucial due to its ability to link many elements of human and physical environments. Timely, accurate, and detailed knowledge of the urban land cover information derived from ... -
Rapid Inspection of Pavement Markings Using Mobile Laser Scanning Point Clouds
(University of Waterloo, 2016-03-28)Intelligent Transportation System (ITS) is the combination of information technology, sensors and communications for more efficient, safer, more secure and more eco-friendly surface transport. One of the most viable forms ... -
Re-evaluating Scattering Mechanisms in Snow-Covered Freshwater Lake Ice Containing Bubbles Using Polarimetric Ground-based and Spaceborne Radar Data
(University of Waterloo, 2015-07-13)Lakes are a prominent feature of the sub-Arctic and Arctic regions of North America, covering up to 40% of the landscape. Seasonal ice cover on northern lakes afford habitat for several flora and fauna species, and provide ... -
Recognizing Features in Mobile Laser Scanning Point Clouds Towards 3D High-definition Road Maps for Autonomous Vehicles
(University of Waterloo, 2017-08-29)The sensors mounted on a driverless vehicle are not always reliable for precise localization and navigation. By comparing the real-time sensory data with a priori map, the autonomous navigation system can transform the ... -
Recognizing the role of gender and food security in type 2 diabetes nutrition education in rural southwestern Ontario
(University of Waterloo, 2014-04-24)Food systems and health systems are interdependent. Historically, however, strategies that focused on the development of these systems evolved in isolation from one another. Non-communicable diseases such as type 2 diabetes ... -
Red coralline algae and climate change: growth, magnesium concentration variability and the development of a new palaeoclimate proxy
(University of Waterloo, 2015-01-22)Past ocean acidification recorded in the geological record facilitates the understanding of rates and influences of contemporary pCO2 enrichment. High resolution proxies of pCO2 and pH can be used to reconstruct ... -
The Regional Integration of Protected Areas: A Study of Canada's National Parks
(University of Waterloo, 2008-08-01)The relationship between protected areas and their regions is complex, dynamic, and often based on social interactions. It is widely accepted that protected areas are not “islands” – rather they are connected to their ... -
Regulatory Dynamics, Institutional Cohesiveness, and Regional Sustainability
(University of Waterloo, 2002)It is generally acknowledged that economic activity continues apace and at the expense of social and ecological integrity while the course of economic development remains far from any approximation of sustainability. Few ... -
