Carbon Cycling in a Glacier Ice Meltwater Impacted Freshwater System of the Canadian High Arctic: Biogeochemical Processes of the Lake Hazen Watershed
(University of Waterloo, 2022-03-23)Accelerated glacier ice mass loss and intensified meltwater fluxes are among principal vectors of change affecting northern latitudes in a warming climate. Aquatic systems impacted by glacier ice meltwater are vulnerable ... -
Development of a Parallel Computational Framework to Solve Flow and Transport in Integrated Surface-Subsurface Hydrologic Systems
(University of Waterloo, 2012-04-11)HydroGeoSphere (HGS) is a 3D control-volume finite element hydrologic model describing fully-integrated surface-subsurface water flow and solute and thermal energy transport. Because the model solves tightly-coupled ... -
Ecology of Juvenile Arctic charr in Canada
(University of Waterloo, 2013-06-14)Increases in global temperatures resulting from climate change have raised concern over potential responses of Arctic charr, <i>Salvelinus alpinus</i>, a cold-adapted freshwater/anadromous fish species in the salmonid ... -
Environmental sensitivities of coupled biogeochemical cycles in anoxic conditions: from soil batch experiments to a bioenergetics approach
(University of Waterloo, 2021-01-26)The ongoing displacement of climate zones has aggravated warming effects at regions from mid- to high-latitudes, affecting terrestrial organic carbon (C) stores. Amplified effects of warming occurring through the winter ... -
Evaluating the role of local climate change on reduced freshwater availability at the Peace-Athabasca Delta using paleolimnology
(University of Waterloo, 2022-06-02)Abundant small, shallow lakes across northern freshwater landscapes are particularly sensitive to alteration of hydrological processes, which makes them vulnerable to multiple potential stressors. At the Peace-Athabasca ... -
Forested Watersheds and Water Supply: Exploring Effects of Wildfires, Silviculture, and Climate Change on Downstream Waters
(University of Waterloo, 2023-06-13)Drinking water supplies for much of society originate in forests. To preserve the capability of these forests to produce clean and easily treatable water, source water supply and protection strategies focus in particular ... -
Identification and characterization of toxic cyanobacteria in two forested maritime watersheds in North America
(University of Waterloo, 2021-06-01)Healthy forested watersheds naturally provide high quality drinking water to communities. However, the integrity and quality of these water sources may be threatened by climate change-exacerbated disturbances such as ... -
Impact of Climate Change on Canadian Water Resources: A Continental-Scale Hydrologic Modelling Study Using Multiple RCM Projections
(University of Waterloo, 2015-05-20)Evidence of climate change is mounting and there is nowadays an increasing international scientific consensus that current climate change is, in part, induced by anthropogenic emissions of greenhouse gases. Climate change ... -
Impact of the Wisconsinian Glaciation on Canadian Continental Groundwater Flow
(University of Waterloo, 2007-01-19)During the Quaternary period, cyclic glaciations have occurred over a global scale as the result of a climatic variability that affected the Earth's atmospheric, oceanic and glacial systems. Quaternary glaciations and their ... -
An interdisciplinary approach to monitoring the hydroecology of thermokarst lakes in Old Crow Flats, Yukon Territory, Canada
(University of Waterloo, 2012-09-28)Lake-rich thermokarst landscapes, such as Old Crow Flats (OCF) in northern Yukon, Canada have been identified as amongst the most vulnerable to climate change. This has raised concerns of the Vuntut Gwitchin First Nation ... -
Investigating Cyanobacterial Communities Across Canada and Characterizing the Seasonality of Cyanobacterial Toxin and Nitrogen Metabolism Genes in the Turkey Lakes Watershed Using Metagenomics
(University of Waterloo, 2023-08-08)The long evolutionary history of gram-negative cyanobacteria has enabled them to tolerate extreme conditions, succeed in numerous habitats, and exploit special nutrients, all while resisting harmful anthropogenic and climate ... -
Landslide Hazard and Climate Change in the Mountain Glacial Environment of Northwest North America
(University of Waterloo, 2017-09-21)The aim of this thesis was to improve the understanding of the complex interactions between climate change and landslide behavior in the periglacial mountain environment of northwest North America. In particular, this ... -
Modelling the Effects of Climate Change on the Surface and Subsurface Hydrology of the Grand River Watershed
(University of Waterloo, 2010-05-06)A numerical modelling analysis of climate change’s precipitation effects on the long-term, averaged surface and subsurface hydrology of the Grand River Watershed (GRW) was undertaken in order to assess possible areas of ... -
The Role of Wetland Pond Permanence in the Assembly of Biological Communities in the Prairie Potholes of Alberta
(University of Waterloo, 2020-05-06)Wetlands in the Prairie Pothole Region (PPR) support numerous biological communities, and the composition of these communities depends on the length of time ponded water is present (i.e., hydroperiod or permanence class). ...
