520 |a"The aim of this report was to assess the sources of nitrogen and phosphorus to the Athabasca and Wapiti- Smoky rivers and evaluate the need to consider groundwater contributions when undertaking simulation modelling of chemical parameters of the Athabasca River during winter. To address the first objective, longitudinal trends in nitrogen (N) and phosphorus (P) were examined for each river system in relation to point-source inputs and the contributions of anthropogenic point sources and agricultural activity to the rivers' nutrient loads were quantified. The importance of groundwater during winter was assessed by examining hydrologic mass balances and changes in dominant ion proportions"--Report summary.
