Spatial heterogeneity in trophic status of shallow lakes on the Boreal Plain: Influence of hydrologic settingDownload
 We used metrics of surface water and groundwater connectivity as explanatory variables in nonparametric regression models to explain the spatial heterogeneity in trophic status of shallow lakes. The concentration of chlorophyll a (Chl a) was used as an indicator of trophic status and was...
Reclamation for aspen revegetation in the Athabasca oil sands: Understanding soil water dynamics through unsaturated flow modellingDownload
Reclamation of mined areas in the Athabasca oil sands region is required by law, with the ultimate goal of revegetating to species characteristic of predisturbance native plant communities. To develop adequate reclamation strategies, an analysis of soil water dynamics is of utmost importance, as...
Interannual variability in trophic status of shallow lakes on the boreal Plain: Is there a climate signal?Download
We explored relations between climate and trophic status of shallow lakes (lake area > 5 ha, mean depth < 3.2 m) located on the subhumid western Boreal Plain of Canada. Correlation and regression analyses were used to assess the association between indicators of climate and satellite-based...
Numerical experiments were developed using different water table depths and soil textures to investigate the impact of aspen harvesting on hydrological processes on the Western Boreal Plain. The effect of harvesting on soil moisture dynamics, fluxes at the water table, and water table fluctuation...
Influence of subhumid climate and water table depth on groundwater recharge in shallow outwash aquifersDownload
 Hypothetical one-dimensional models of unsaturated flow were used to estimate the probability of groundwater recharge to shallow, glacial outwash aquifers. Simulations were supported by field data, previous three-dimensional modeling, and cross-sectional models of water table response to...
Particle density is a fundamental soil physical property, yet values of soil and organic matter particle density (ρs and ρo) vary widely in the literature. We measured particle density of organic soils from five wetland types, and from exposed sediments of drying ponds, in northern Alberta,...
Simulations of fully coupled lake‐groundwater exchange in a subhumid climate with an integrated hydrologic modelDownload
 A fully coupled, integrated surface water/groundwater model was used to study hydrologic controls on lake-groundwater interaction in the subhumid, Boreal Plains of northern Alberta, Canada. Findings from a previous water budget study indicate that lakes on the outwash landscape capture...
