Channel Form And Processes In A Formerly Glaciated Terrain, Nathaniel Bergman
Channel Form And Processes In A Formerly Glaciated Terrain, Nathaniel Bergman
Electronic Thesis and Dissertation Repository
Despite that many places around the world in general, and North America in particular, were glaciated during the last ice age, relatively little is known about rivers that evolved over these landscapes once they deglaciated. These rivers are commonly categorized as alluvial with a glacial legacy, and often described as plain gravel-bed or sand-bed rivers. Alternatively, they are considered to be bedrock rivers when the glacial deposits were eroded and underlying rock was exposed. However, ignoring the glacial history of these rivers is scientifically wrong and they should be termed "semi-alluvial". This work shows that classification is important, not only …
Uncertainty Analysis Of The Performance Of A System Of Best Management Practices For Achieving Phosphorus Load Reduction To Surface Waters, Jason D.M. Igras
Uncertainty Analysis Of The Performance Of A System Of Best Management Practices For Achieving Phosphorus Load Reduction To Surface Waters, Jason D.M. Igras
Electronic Thesis and Dissertation Repository
The repeated occurrence of Lake Erie’s harmful algal blooms suggests an inadequate phosphorus management system that results in excessive loads to the lake. In response, Canadian and United States’ governments have issued a new management objective, a 40% reduction in total and dissolved reactive phosphorus loads relative to 2008. To provide scientific evidence to guide managers toward achieving their management objective, we used the International Organization of Standardization (ISO) 31010 Bowtie Risk Analysis Tool to analyze the performance of the phosphorus management system. The effectiveness of agricultural best management practices (BMPs) and their adoption were combined into a Bayesian belief …
The Influence Of Capacity And Attitudes In The Use Of Water Quality Citizen Science And Volunteer Benthic Monitoring In The Freshwater Management Activities Of Ontario’S Conservation Authorities, Sonja Teichert
Electronic Thesis and Dissertation Repository
The contribution of non-experts to environmental management has been significant and continues to flourish through their participation in citizen science. Despite its growth as an interdisciplinary field of enquiry, there are many gaps in our understanding of the role that citizen science may play in the future of environmental management. In Ontario, Canada, due to funding cuts and infrastructural changes over the past two decades, the provincial government’s ability to monitor changes in freshwater resources had been severely limited. This has resulted in downloading water monitoring to municipalities through their conservation authorities (CAs) which are watershed-based, quasi-governmental water management agencies. …
