Biogeochemical Hotspots: Role of Small Water Bodies in Landscape Nutrient Processing
(University of Waterloo, 2017-05-09)Increased loading of nitrogen and phosphorus from agricultural and urban intensification has led to severe degradation of inland and coastal waters. Lakes, reservoirs, wetlands, and streams retain and transform these ... -
Coagulant addition for managing sediment-associated phosphorus bioavailability to prevent cyanobacterial blooms in drinking water reservoirs
(University of Waterloo, 2021-08-27)To ensure the uninterrupted supply of adequate amounts of drinking water, many utilities rely on reservoirs for raw (i.e., untreated) water storage prior to treatment. For example, reservoirs are integral to storing water ... -
Effect of phosphorus doping on Young's modulus and residual stress of polysilicon thin films
(University of Waterloo, 2010-08-31)On-chip characterization devices have been used to extract the Young’s modulus, average stress and stress gradient of polysilicon doped with phosphorus using thermal diffusion. Devices for extracting the Young’s modulus, ... -
A Random Forest in the Great Lakes: Exploring Nutrient Water Quality in the Laurentian Great Lakes Watersheds
(University of Waterloo, 2020-09-22)A data driven approach was used in this study to investigate the drivers of nutrient water quality across the Laurentian Great Lakes drainage basin. Monitored time series of nutrient water quality and discharge were modelled ... -
Recoupling the Livestock Nutrient Economy: A Path forward for Water Quality Improvement
(University of Waterloo, 2019-09-23)Intensification of farming operations and increased nutrient application rates have led to higher crop yields and greater food security. At the same time, widespread use of commercial nitrogen (N) and phosphorus (P) ... -
Spatial and Temporal Trends in Water Quality in a Mixed-Use Landscape: Agriculture vs. Urban Areas
(University of Waterloo, 2018-10-22)The eutrophication of aquatic ecosystems is a growing water quality concern as it can promote the proliferation of harmful algal blooms that have severe environmental, health, and economic impacts. In United States alone, ...
