Can alluvial landforms attenuate post-wildfire lake sedimentation rates and external phosphorus inputs?
(University of Waterloo, 2022-12-22)Severe large-scale landscape disturbance in forested source water regions by wildfire can increase the transfer of fine sediment and associated phosphorus (P) to aquatic systems. Notably, the subsequent mobilization of ... -
Contemporary Forest Harvesting Impacts on Drinking Water Quality and Treatability
(University of Waterloo, 2019-10-31)Forested watersheds supply ~75% of global accessible freshwater resources and serve as important sources of drinking water. Both natural and anthropogenic landscape disturbances in these regions can deteriorate water quality ... -
Conventional and Oxidant-amended Biofiltration to Improve Treatment Resilience in Drinking Water Systems Vulnerable to Wildfire
(University of Waterloo, 2024-01-26)Climate-change-exacerbated landscape disturbances can create obstacles for the provision of safe drinking water. The threats posed by wildfires are of particular concern due not only to the potentially extreme nature of ... -
Deeper Burning Increases Available Phosphorus, Promotes Moss Growth, and Carbon Dioxide Uptake in a Fen Peatland One-Year Post-Wildfire in Fort McMurray, AB
(University of Waterloo, 2019-01-25)Carbon storage in northern peatlands is estimated to be ~795 Tg, equivalent to ~40% of atmospheric CO2. Peatlands are dominant features of the Western Boreal Plains (WBP), which are experiencing a regime shift to a ... -
Drinking Water Treatment Technology Resilience for Management of Severely Deteriorated Water after Wildfire
(University of Waterloo, 2021-09-29)Severe wildland fire is occurring with increased frequency in many regions and can be potentially catastrophic for the provision of safe drinking water due to increasingly variable or deteriorated source quality. Deteriorated ... -
Estimating PM2.5 Concentrations Using 3 KM MODIS AOD Products: A Case Study in British Columbia, Canada
(University of Waterloo, 2019-04-30)PM2.5 refers to fine particles with diameters smaller than 2.5 μm. The rising level of PM2.5 reveals adverse effects on climate change, economic losses, international conflicts, and public health. Exposure to the high level ... -
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 ... -
Impact of the Kenow wildfire on the form and mobility of particulate phosphorus in gravel-bed rivers at large basin scales: Implications for downstream propagation
(University of Waterloo, 2022-05-25)Landscape disturbance by wildfire in forested source water regions can significantly accelerate fine sediment transport from hillslopes to receiving streams. The mobilization of fine sediment and associated nutrients, such ... -
Quantifying and Modelling Post-Wildfire Sediment Production in Waterton Lakes National Park
(University of Waterloo, 2021-12-16)High-severity wildfires can increase sediment mobility and erosion rates in burned landscapes which increase the delivery of fine sediment to receiving streams. The downstream propagation of these pyrogenic materials can ... -
Toxicity and bioaccumulation of sediment-associated metals and elements from wildfire impacted streams of southern Alberta on Hyalella azteca
(University of Waterloo, 2013-10-02)There is increasing global recognition of the effects of large scale land disturbance by wildfire on a wide range of water and ecosystem services. In 2003, the Lost Creek wildfire burned a contiguous area of 21,000 ha on ...
