Snowmelt, low temperatures and agricultural practices such as tillage and tile drainage impact biogeochemical cycles and the runoff of excess nutrients to Canadian lakes. Eutrophication of large lakes such as Lake Erie and Lake Winnipeg are environmental disasters that result from this runoff. There is great interest in hydro-biogeochemical tools to support nutrient management and help with recommendations for beneficial management practices (BMP). However, deficiencies in the representation of cold regions hydro-biogeochemical processes in existing catchment, instream and lake models make their application problematic. A combined experimental-modelling program focused on the development of multi-scale models of water quality suitable for cold regions has been undertaken to improve upon existing prediction tools, develop a suite of new generation modelling systems, and advance theory. This talk will share some of the achievements and present a roadmap for delivering better research and management tools for Canada to support sustainable development and climate change adaptation.
