Assessing the use of δ18O-PO4 analysis for tracing source inputs and the cycling of phosphorus: Applications to the Grand River
(University of Waterloo, 2014-05-01)The use of δ18O- PO4 analysis was assessed for the Grand River, a highly impacted river in Southern Ontario that receives inputs from 30 WWTPs. Significant nutrient inputs within the watershed have led to prolific aquatic ... -
Chlorophyll-a Mapping in a Large Lake Using Remote Sensing Imagery: A Case Study of Western Lake Ontario
(University of Waterloo, 2024-04-23)Western Lake Ontario (WLO) and Hamilton Harbour (HH) experience significant eutrophication challenges. Despite an overall decrease in the limiting nutrient phosphorus (P) inputs, recurrent nuisance (Cladophora) and ... -
Influence of a dammed reservoir on nutrient (N, P, Si) loads and ratios of the Thames River, Ontario
(University of Waterloo, 2021-01-20)The increasing frequency and severity of harmful algal blooms (HABs) in Lake Erie have been troubling developments in the past few decades. Excess loads of phosphorus (P) from the watershed are considered to be a primary ... -
Modeling the growth dynamics of <em>Cladophora</em> in eastern Lake Erie
(University of Waterloo, 2005)<em>Cladophora glomerata</em> is a filamentous green alga that currently forms extensive blooms in nearshore areas of Lake Ontario, eastern Lake Erie, Lake Michigan, and isolated locations in Lake Huron. The biomass, ... -
Phosphorus retention and transformation in a dammed reservoir of the Thames River, Ontario: Impacts on phosphorus load and speciation
(Elsevier, 2022-02)Extensive efforts are underway to reduce phosphorus (P) export from the Lake Erie watershed. On the Canadian side, the Thames River is the largest tributary source of P to Lake Erie’s western basin. However, the role of ... -
Quantifying the Groundwater Component within the Water Balance of a Large Lake in a Glaciated Watershed: Lake Pyhäjärvi, SW Finland
(University of Waterloo, 2012-01-20)Accurate estimates of the amount of groundwater entering a lake on a yearly basis may provide valuable information for assessing contaminant loadings such as nutrient mass fluxes and the subsequent contribution of groundwater ... -
Quantifying the role of reservoirs in altering phosphorus dynamics using a combination of data analysis and process modeling
(University of Waterloo, 2022-04-29)Excess phosphorus (P) from agricultural watersheds promotes eutrophication in downstream aquatic systems. Reservoirs retain P generated from farm fields and protect downstream waters. Reservoirs also act as hotspots for P ... -
The role of submersed macrophytes in river eutrophication and biogeochemical nutrient cycling
(University of Waterloo, 2012-09-28)The goal of this work is to contribute to the understanding eutrophication in large rivers with a detailed study of the Grand River, an impacted river in highly agricultural and urbanized Southern Ontario. It focuses on ...
