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.
CURRENT RESEARCH
- Nutrient and contaminant movement in groundwater systems
- Nutrient loading to lake and river systems
- Development of hydrologic Decision Support tools
- Simplification methods for hydrologic modeling (emulators, machine learning, analytic solutions)
- Uncertainty analysis and forecasting
- Groundwater flow and transport simulation
- Water availability and source water protection
- Groundwater/surface-water interaction (flow and chemistry)

Water Quality and Hydrology of Whitefish (Bardon) Lake, Douglas County, Wisconsin, With Special Emphasis on Responses of an Oligotrophic Seepage Lake to Changes in Phosphorus Loading and Water Level Water Quality and Hydrology of Whitefish (Bardon) Lake, Douglas County, Wisconsin, With Special Emphasis on Responses of an Oligotrophic Seepage Lake to Changes in Phosphorus Loading and Water Level
Whitefish Lake, which is officially named Bardon Lake, is an oligotrophic, soft-water seepage lake in northwestern Wisconsin, and classified by the Wisconsin Department of Natural Resources as an Outstanding Resource Water. Ongoing monitoring of the lake demonstrated that its water quality began to degrade (increased phosphorus and chlorophyll a concentrations) around 2002 following a...

Simulation of contributing areas and surface-water leakage to potential replacement wells near the community of New Post, Sawyer County, Wisconsin, by means of a two-dimensional ground-water flow model Simulation of contributing areas and surface-water leakage to potential replacement wells near the community of New Post, Sawyer County, Wisconsin, by means of a two-dimensional ground-water flow model
A two-dimensional, steady-state ground-water-flow model of the shallow ground-water-flow system near the community of New Post, Sawyer County, Wis., was refined from an existing model of the area. Hydraulic-conductivity and recharge values were not changed from the existing model for the scenario simulations described in this report. Rather, the model was refined by adding detail along...

Ground-Water Flow in the Vicinity of the Ho-Chunk Nation Communities of Indian Mission and Sand Pillow, Jackson County, Wisconsin Ground-Water Flow in the Vicinity of the Ho-Chunk Nation Communities of Indian Mission and Sand Pillow, Jackson County, Wisconsin
An analytic element ground-water-flow model was constructed to help understand the ground-water-flow system in the vicinity of the Ho-Chunk Nation communities of Indian Mission and Sand Pillow in Jackson County, Wisconsin. Data from interpretive reports, well-drillers' construction reports, and an exploratory augering program in 2003 indicate that sand and gravel of varying thickness (0...

Effects of climate and land management change on streamflow in the driftless area of Wisconsin Effects of climate and land management change on streamflow in the driftless area of Wisconsin
Baseflow and precipitation in the Kickapoo River Watershed, located in the Driftless Area of Wisconsin, exhibit a step increase around 1970, similar to minimum and median flows in many other central and eastern USA streams. Potential effects on streamflow due to climatic and land management changes were evaluated by comparing volumetric changes in the hydrologic budget before and after...

Hydrogeologic characteristics of the St. Croix River basin, Minnesota and Wisconsin: Implications for the susceptibility of ground water to potential contamination Hydrogeologic characteristics of the St. Croix River basin, Minnesota and Wisconsin: Implications for the susceptibility of ground water to potential contamination
Population growth in the St. Croix River Basin in Minnesota and Wisconsin has intensified concerns of county resource managers and the National Park Service, which is charged with protecting the St. Croix National Scenic Riverway, about the potential for ground-water contamination in the basin. This report describes a previously developed method that was adapted to illustrate potential...

Simulation of the shallow ground-water-flow system near Grindstone Creek and the community of New Post, Sawyer County, Wisconsin Simulation of the shallow ground-water-flow system near Grindstone Creek and the community of New Post, Sawyer County, Wisconsin
A two-dimensional, steady-state ground-water-flow model of Grindstone Creek, the New Post community, and the surrounding areas was developed using the analytic element computer code GFLOW. The parameter estimation code UCODE was used to obtain a best fit of the model to measured water levels and streamflows. The calibrated model was then used to simulate the effect of ground-water...

Scale effects of hydrostratigraphy and recharge zonation on base flow Scale effects of hydrostratigraphy and recharge zonation on base flow
Uncertainty regarding spatial variations of model parameters often results in the simplifying assumption that parameters are spatially uniform. However, spatial variability may be important in resource assessment and model calibration. In this paper, a methodology is presented for estimating a critical basin size, above which base flows appear to be relatively less sensitive to the...

Simulation of the shallow hydrologic system in the vicinity of Middle Genesee Lake, Wisconsin, using analytic elements and parameter estimation Simulation of the shallow hydrologic system in the vicinity of Middle Genesee Lake, Wisconsin, using analytic elements and parameter estimation
Middle Genesee Lake is a ground-water flow-through lake located in a developing area in southeastern Wisconsin. Because the lake is in good connection with the shallow ground-water system, hydrologic stresses to the shallow ground-water system could adversely affect the lake system. In order to assess the effects of potential stresses on the lake, a study was completed by the U.S...
