Analyzing the impacts of road construction on the development of a poor fen in Northeastern Alberta, Canada
(University of Waterloo, 2015-05-25)Linear disturbances such as powerline rights of way, seismic lines and roads are common in areas of intensive resource development. Roads that bisect wetlands can alter their hydrologic connectivity on a local or landscape ... -
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 ... -
An evaluation of the water balance and moisture dynamics within Sphagnum mosses following the restoration (rewetting) of an abandoned block-cut bog
(University of Waterloo, 2011-09-30)Artificial drainage networks established throughout peatlands during the peat extraction process often remain active following abandonment, maintaining a water table relatively far from the surface of the peat and hindering ... -
Fen restoration on a bog cut down to sedge peat: A hydrological assessment of rewetting and the impact of a subsurface gyttja layer
(University of Waterloo, 2013-02-22)Vacuum harvested peatlands do not easily regain their hydrological function after peat production therefore restoration is required to create hydrological conditions appropriate for the growth of peat producing fen plant ... -
Genesis and hydrological function of an African mire: understanding the role of peatlands in providing ecosystem services in semi-arid climates
(University of Waterloo, 2015-01-06)The effects of changes in climate or landscape on wetland ecosystems in drier regions need to be considered within the context of natural processes. Hydrological processes are a key component in the development and maintenance ... -
The Hydrochemical Fate and Transport of Treated Domestic Wastewater Contaminants During a Wastewater Polishing Experiment in a Sub-Arctic Ladder Fen Peatland
(University of Waterloo, 2016-09-27)Protecting northern aquatic ecosystems is critical to ensuring the sustained use of these environments; however, with increasing industrial and residential development pressures in this region the safe and effective treatment ... -
The hydrological interactions within a mine impacted peatland, James Bay Lowland, Canada
(University of Waterloo, 2015-08-05)The development of a large open-pit diamond mine in the James Bay Lowland, one of the world’s largest wetland complexes, provides insight into hydrological processes that sustain wetlands in the region. The bog and fen ... -
Hydrophysical evolution, soil water dynamics, and productivity of Sphagnum carpets in a regenerating cutover peatland
(University of Waterloo, 2014-11-26)The physical and hydrologic characteristics of cutover peatlands often inhibit the regeneration of typical peatland vegetation, particularly the keystone peat-forming genus <i>Sphagnum</i>, in the absence of active ... -
Influence of Antecedent Soil Moisture and Rainfall Rate on the Leaching of Nitrate and Phosphate from Intact Monoliths of Agricultural Soil
(University of Waterloo, 2010-05-18)The export of nitrogen (N) and phosphorus (P) from agricultural catchments is a major problem worldwide. The export of these nutrients is largely driven by storm events, and the hydrologic response of catchments varies ... -
Integration of Satellite Data, Physically-based Model, and Deep Neural Networks for Historical Terrestrial Water Storage Reconstruction
(University of Waterloo, 2021-04-08)Terrestrial water storage (TWS) is an essential part of the global water cycle. Long-term monitoring of observed and modeled TWS is fundamental to analyze droughts, floods, and other meteorological extreme events caused ... -
The Role of Ericaceous Shrubs in the Surface Water Balance and Soil Water Availability of Cutover Peatland, Québec
(University of Waterloo, 2008-09-12)Peatlands are carbon sinks and occupy approximately 13% of Canada’s terrestrial surface of which 0.02% have been harvested for horticultural peat. The extraction of peat from natural peatlands alters the hydrology which ... -
Saturated and vadose zone fate and transport of a continuously released tracer in a sub-arctic bog peatland
(University of Waterloo, 2017-02-22)In Ontario’s James Bay Lowland, sub-arctic bog and fen peatlands make up 90% of the landscape. Increasing resource extraction operations in this area pose a risk of contaminant release into these systems, both intentional ... -
Seasonal and Event-based Hydrological Response in a Hillslope-Riparian Zone setting of the Temperate Beverly Swamp
(University of Waterloo, 2015-06-29)Wetland ecosystems are an integral part of the landscape, providing vital habitat for species at risk, while providing important services in hydrological and biogeochemical cycling. Since many of the habitats and ... -
Using stable water isotopes to partition source water contribution and assess spatio-temporal source water dynamics of wetlands ecosystems in the eastern Canadian Rocky Mountains
(University of Waterloo, 2022-01-28)Subalpine and montane regions of the Canadian Rocky Mountains are expected to experience continued changes in hydrometeorological processes due to anthropogenically-tied climate warming. These regions are important in ...
