Characterization of the Physical and Hydraulic Properties of Peat Impacted by a Temporary Access Road
(University of Waterloo, 2015-10-07)Due to the disruption of hydrology and water quality, permanent installation of roads and well pads is a practice that is discouraged. It is becoming more common to install temporary structures, which can subsequently be ... -
Chemical characterization of construction materials and solute transport in peat from the Nikanotee Fen watershed at the Athabasca oil sands region, Alberta, Canada
(University of Waterloo, 2017-02-22)Overburden and tailings materials from oil sands production were used as construction materials as part of a novel attempt to create a self-sustaining, peat accumulating fen-upland ecosystem. To evaluate the potential for ... -
Dissolved organic carbon production and transport in a constructed watershed in the Athabasca Oil Sands Region, Alberta
(University of Waterloo, 2018-01-23)Within the Western Boreal Plains, a significant amount of surface cover has been removed through open-pit oil sands mining activities, which includes fen peatlands. Fen construction has been performed on the post-oil sands ... -
Effects of Tillage and Fertilizer Placement on Subsurface Phosphorus Loss Following Fall Manure Application over the Non-Growing Season
(University of Waterloo, 2020-09-25)Increased phosphorus (P) loadings from agricultural runoff into the Great Lakes can lead to eutrophication, resulting in harmful algal blooms and hypoxic conditions. Many studies have demonstrated that subsurface tile ... -
Evaluating parameter fitting and model design for unsaturated processes in peatlands
(University of Waterloo, 2019-04-08)Growing Sphagnum moss for peatland restoration and fibre farming requires the proper moisture regime be maintained; thus, there is a desire to optimize growth by creating ideal hydrological conditions. Sphagnum mosses have ... -
Hydrological and Geochemical Implications of Aquifer Depressurization on Expansive Peatland Systems in the Hudson/James Bay Lowlands
(University of Waterloo, 2016-04-08)The ecological integrity of the peatlands of the Hudson/James Bay Lowlands (HJBL) is vulnerable to hydrological changes associated with climate change and resource development. Dewatering of an open-pit mine (the DeBeers ... -
The hydrology and geochemistry of a saline spring fen peatland in the Athabasca oil sands region of Alberta
(University of Waterloo, 2014-05-01)Due to the nature of the regional geology and the bitumen extraction process, the post-mined landscape of Canada’s oil sands region will have a much higher concentration of dissolved salts than it did prior to mining. As ... -
Hydrology and Nutrient Biogeochemistry of Shallow Pond-Peatland Complexes, Hudson Bay Lowlands
(University of Waterloo, 2018-06-25)Across the circumpolar north, the degradation of permafrost in tundra and peatland landscapes has resulted in significant changes to land cover, including an increase in the extent of thermokarst landforms. Climatically-driven ... -
Hydrology of a Constructed Fen Watershed in a Post-mined Landscape in the Athabasca Oil Sands Region, Alberta, Canada
(University of Waterloo, 2016-01-20)Peatlands (i.e., wetlands with organic soil) cover approximately 12% of Canada’s total land area, 18% of Alberta’s land base and nearly half of the landscape in Canada’s Western Boreal Plain. Some of these peatlands overlay ... -
The hydrology of the Bois-des-Bel bog peatland restoration: A tale of two scales
(University of Waterloo, 2012-09-21)Vacuum harvested peatlands typically do not spontaneously regenerate peatland species and more importantly the peat-forming Sphagnum mosses. Thus harvested and abandoned peatlands require restoration to return the peat-forming ... -
The Impacts of Diamond Mining to Peatlands in the James Bay Lowlands
(University of Waterloo, 2013-02-21)Approximately 7000 to 8000 years ago when Hudson Bay became ice-free the Tyrrell Sea flooded the Hudson basin and deposited fine grained marine sediments overlaying the previous glacial tills. Coincident with the ablation ... -
Impacts of resource access road crossings on ecohydrology and carbon dynamics of boreal peatlands
(University of Waterloo, 2019-09-04)Resource access road crossings are expected to alter peatland ecohydrological properties by obstructing surface and sub-surface water flows, providing favorable conditions to stimulate microbial activity, and ultimately ... -
Multiple Methods for Assessing the Sustainability of Shallow Subarctic Ponds in Churchill Region: Hudson Bay Lowland, Canada
(University of Waterloo, 2011-09-30)This thesis examines the occurrence of hydrologic variability in subarctic ponds within the Churchill region of the Hudson Bay Lowland (HBL) and investigates the utility of using remote sensing studies to characterize ... -
Remote sensing and biophysical monitoring of vegetation, terrain attributes and hydrology to map, characterise and classify wetlands of the Maputaland Coastal Plain, KwaZulu-Natal, South Africa
(University of Waterloo, 2014-05-16)The Maputaland Coastal Plain is situated in north-eastern KwaZulu-Natal Province, South Africa. The Maputaland Coastal Plain and underlying aquifer are two separate but inter-linked entities. This area with high permeable ...
