Paul F Juckem

Paul Juckem is a Hydrologist with the Upper Midwest Water Science Center.

His expertise in groundwater flow and transport modeling is used in studies of regional water availability, groundwater/surface-water interaction, and water quality characterization and prediction for lakes, streams, and aquifers.  Current work involves: leading the development of tools to inform resource managers about the sources, timing, and fate (forecasts) of nutrients in aquifers, wells, and waterbodies; investigating factors that influence groundwater age distributions and travel times within aquifers; assessing the role of groundwater/surface-water interactions along flood plains in attenuating peak flows; mapping the probability of contaminant plume extents in aquifers using Analytic Element groundwater flow models and Monte Carlo techniques; and evaluating effects of water level fluctuations and water quality in shallow lakes.
