Advancing groundwater vulnerability assessment in the Yukon and Northwest Territories
(University of Waterloo, 2023-05-15)Reliance on groundwater for drinking water supplies varies across the Yukon and Northwest Territories (NWT), with usage of up to 97% in Yukon and 5% in NWT. Groundwater vulnerability assessments, which review water quality ... -
Empirical Valuation of Watershed Services: A Spatial Instrumental Variable Regression Model of Treatment Plants in Canada
(University of Waterloo, 2023-05-14)We investigate the impact of forest cover on drinking water treatment costs in Canada using the 2015 Survey of Drinking Water Plants (SDWP). We estimate proportion of forest, urban, and agricultural land cover in the sub-sub ... -
How Does Moss Resist Evaporation? Towards Elucidating Site-Specific Influences on Sphagnum Moss Resistance
(University of Waterloo, 2023-05-16)While multiple approaches to exist to quantify plant resistance to evaporation, these methods assume that the vegetation is vascular despite many ecosystems, such as peatlands, dominated by a surface cover of mosses. Mosses ... -
Influence of dynamic river stage on the vulnerability of water wells and structure foundations in cold regions
(University of Waterloo, 2023-05-15)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 in ... -
Legacy Phosphorus Across Canada: Insights from a 60-Year Dataset
(University of Waterloo, 2023-05-15)Human activities over decades of agriculture and urbanization have altered phosphorus (P) cycling, posing a threat to water quality and ecosystem function. Algal blooms have become a pervasive problem in both small and ... -
Modelling Legacy Nitrogen Dynamics in the Transboundary Lake Erie Watershed
(University of Waterloo, 2023-05-16)Lake Erie is a source of drinking water, recreation, and commercial opportunity for both the United States and Canada, making the protection of its water quality essential. In the past decades, Lake Erie's ecosystems have ... -
Monitoring lake ice phenology from CYGNSS: Algorithm development and assessment using Qinghai Lake, Tibet Plateau, as a case study
(University of Waterloo, 2023-05-14)This study introduces the first use of Global Navigation Satellite System Reflectometry (GNSS-R) for monitoring lake ice phenology. This is demonstrated using Qinghai Lake, Tibetan Plateau, as a case study. Signal-to-Noise ... -
Quantitative insights into phosphorus loadings and speciation in urban catchments
(University of Waterloo, 2023-05-16)Phosphorus (P) loadings in stormwater runoff drained from urban landscapes causes eutrophication in aquatic ecosystems downstream of urban areas. Many recent research have addressed urban P dynamics to improve understanding ... -
Short-term predictions of transient shallow groundwater levels at local scale using data-driven models
(University of Waterloo, 2023-05-15)Groundwater is a critical natural resource for human activities and a vital component of the hydrological cycle. The fluctuation of groundwater level (GWL) can be induced by the interplay of several natural processes and ... -
URBAN PHOSPHORUS SPECIATION AND EXPORT LOADS: A PAIRED SEWERSHED FIELD AND MODELING STUDY
(University of Waterloo, 2023-05-14)In this study, annual and seasonal loads of phosphorus (P) exported from two neighbouring urban sewersheds (AJE and AJW) discharging into Lake Ontario were estimated. The following different chemical pools of P were ...
