Characterizing Aspects of Groundwater Flow in Discontinuous Permafrost Terrain, Within the Central Mackenzie Valley, NWT
(University of Waterloo, 2021-05-26)With recent developments in oil and gas exploration technologies that have opened regions of Canada’s northern territories and the threat of climate change, uncertainties around how these factors may impact the environment ... -
Examining Hydrogeological Processes in Freezing Soils using Remote Geophysical and Numerical Techniques
(University of Waterloo, 2019-02-11)The work presented in this thesis aimed to demonstrate the use of remote geophysical methods and numerical modelling to address questions related to hydrogeological processes in freezing soils. Two different study areas ... -
Fate and Transport of Land Applied Waste Greenhouse Feed Water During Field Infiltration Experiments
(University of Waterloo, 2016-04-29)Because of the high concentration of greenhouses in Essex County, greenhouse feed water discharges are considered as a potential contributor to nuisance and harmful algal blooms and hypoxia in western Lake Erie. Waste ... -
Fate and Transport of Synthetic DNA in Surface Water
(University of Waterloo, 2021-09-29)Unlike conventional salt or dye tracers, artificial/synthetic DNA hydrologic tracers are essentially non-toxic and several can be used simultaneously. These features have implications for DNA to be used to better understand ... -
A field study of event based, seasonally affected, depression focused recharge in glaciated terrain
(University of Waterloo, 2019-04-26)To observe the dynamics of depression focused recharge (DFR) and the effects of seasonality related to transient surface water features, a field scale experiment was designed and conducted within glacial terrain in southern ... -
How a dry year affects spatial variability of ground thaw and changes the hydrology of a small Arctic watershed
(University of Waterloo, 2023-09-28)The summer of 2021 in the Inuvik area, NWT was warm and dry. As recorded in Siksik Creek, a sub-catchment of Trail Valley Creek located 50 km north-east of Inuvik, this was the 7th warmest summer and driest July recorded ... -
Influence of Dynamic River Stage on The Vulnerability of Water Wells and Structure Foundations in Cold Regions
(University of Waterloo, 2023-07-12)Groundwater is important for people in Northern Canada, yet the groundwater protection protocols and water well vulnerability assessments designed for other warmer regions of Canada may not be applicable to communities ... -
The influences of spatially variable rainfall and localized infiltration on groundwater recharge in a water management context
(University of Waterloo, 2020-10-27)Water management involves monitoring, predicting, and stewarding the quality and quantity of groundwater recharge at the watershed scale. Recharge sustains baseflow to streams and replenishes water extracted by pumping at ... -
Investigating new approaches for mapping groundwater systems in karstic carbonate bedrock: A case study in the Early Silurian formations of the Niagara Escarpment cuesta, southern Ontario, Canada
(University of Waterloo, 2019-03-20)The Ontario Geological Survey conducts geoscience mapping that is designed to support groundwater resource investigations across the province. Recent geological mapping in the Early Silurian carbonate bedrock in southern ... -
Quantifying Groundwater Recharge Under Dynamic Seasonality in Cold Climates
(University of Waterloo, 2018-01-18)Estimating groundwater recharge in cold climates during periods of dynamic seasonality such as winter melt periods and spring freshets is challenging due to subsurface heterogeneities and the complexity of vadose zone ...
