My current research is focused on understanding the magnitude and dynamics of nutrient legacies in agricultural landscapes in the Baltic region and how they contribute to river loads to the sea. To that end, I develop and apply numerical models to try and capture the effects of historical agricultural practices and water management on nutrient cycles at the watershed scale.
I have side interests in programming and computational techniques, and a long experience in modeling groundwater flow and transport processes in deep fractured bedrock and engineered buffer materials to support the risk assessment for final nuclear waste repositories.
Nutrients that accumulate in soils and in the bottom sediments of lakes and streams have a long-term impact on eutrophication in the Baltic Sea. The modeling project “Legacy nutrient dynamics in the Baltic Sea catchment: implications for managing eutrophication” will estimate the magnitude of these legacies and suggest appropriate measures.
