Modelling Monthly Water Balance: The Role of Lake Storage and Snow-Related Processes

Year: 2020, 2020
Member of: Trent University Graduate Thesis Collection
Name(s): Creator (cre): LeGrand, Matthew Cody LeGros, Thesis advisor (ths): Buttle, James M, Thesis advisor (ths): Metcalfe, Robert A, Degree committee member (dgc): Lafleur, Peter M, Degree committee member (dgc): Aherne, Julian, Degree granting institution (dgg): Trent University
Abstract: <p>Water balance models calculate water storage and movement within drainage basins, a primary concern for many hydrologists. A Thornthwaite water balance model (H2OBAAS) has shown poor accuracy in predicting low flows in the Petawawa River basin in Ontario, so lake storage and winter snow processes were investigated to improve the accuracy of the model. Lake storage coefficients,… more

The Influence of Nitrogen Deposition on Community Composition in Pinus banksiana Forests Across Northwestern Canada

Name(s): Creator (cre): Vandinther, Nicole, Thesis advisor (ths): Aherne, Julian, Degree committee member (dgc): Sager, Eric, Degree committee member (dgc): Watmough, Shaun, Degree granting institution (dgg): Trent University
Abstract: <p>Anthropogenic atmospheric emissions and subsequent deposition of nitrogen (N) can affect N-sensitive habitats and lead to shifts in plant species community composition. This study assessed the effects of N deposition on plant community composition for Jack pine forests across northwestern Canada and across a smaller subset of sites surrounding the Athabasca Oil Sands Region (AOSR) using… more

Temporal variation of dissolved organic matter and diffusive gradient in thin films-labile mercury in the Quesnel river, BC, and the Goose Creek tributary of Churchill river, MB

Name(s): Creator (cre): Sarswat, Rishabh, Thesis advisor (ths): Aherne, Julian, Degree committee member (dgc): Gueguen, Celine, Degree committee member (dgc): Sager, Eric, Degree granting institution (dgg): Trent University
Abstract: <p>This study examined dissolved organic matter (DOM) and labile Mercury (from diffusive gradient in thin films (DGT)) in the Quesnel river, British and the Goose creek tributary of the Churchill river, Manitoba. DOM properties were measured with optical measurements of absorption coefficient (a254), spectral slopes (S275-295, SR) and fluorescence indices (HIX, BIX, FI). The DOC proxy… more

Soil Geochemistry and Normative Mineralogy across Canada

Name(s): Creator (cre): Aldis, Margot, Thesis advisor (ths): Aherne, Julian, Degree committee member (dgc): Grunsky, Eric, Degree committee member (dgc): Posch, Max, Degree granting institution (dgg): Trent University
Abstract: <p>Soils play a crucial role in ecosystem functioning, for example, soil minerals provide important provisioning and regulate ecosystem services. This study used major soil oxides from the North American Soil Geochemical Landscapes Project (n=560) to assess elemental associations and infer soil minerals through exploratory data analysis and to determined quantitative soil mineralogy using a… more
