W. Barclay Shoemaker
W. Barclay Shoemaker is a research hydrologist for the U.S. Geological Survey in Davie, Florida. His interests include numerical modeling, micrometeorology, and hydrologic characterization for conflicts over water. Barclay was invited to appear on a National Public Radio (NPR) show titled "Florida Aquifer and Saltwater". He has authored numerous USGS technical reports and journal articles; and has served as peer-reviewer for scientific journals including Ground Water and Water Resources Research.

Estimating changes in heat energy stored within a column of wetland surface water and factors controlling their importance in the surface energy budget Estimating changes in heat energy stored within a column of wetland surface water and factors controlling their importance in the surface energy budget
Changes in heat energy stored within a column of wetland surface water can be a considerable component of the surface energy budget, an attribute that is demonstrated by comparing changes in stored heat energy to net radiation at seven sites in the wetland areas of southern Florida, including the Everglades. The magnitude of changes in stored heat energy approached the magnitude of net...

Important observations and parameters for a salt water intrusion model Important observations and parameters for a salt water intrusion model
Sensitivity analysis with a density-dependent ground water flow simulator can provide insight and understanding of salt water intrusion calibration problems far beyond what is possible through intuitive analysis alone. Five simple experimental simulations presented here demonstrate this point. Results show that dispersivity is a very important parameter for reproducing a steady-state...

Comparison of Estimated Areas Contributing Recharge to Selected Springs in North-Central Florida by Using Multiple Ground-Water Flow Models Comparison of Estimated Areas Contributing Recharge to Selected Springs in North-Central Florida by Using Multiple Ground-Water Flow Models
Areas contributing recharge to springs are defined in this report as the land-surface area wherein water entering the ground-water system at the water table eventually discharges to a spring. These areas were delineated for Blue Spring, Silver Springs, Alexander Springs, and Silver Glen Springs in north-central Florida using four regional ground-water flow models and particle tracking...

Potential for saltwater intrusion into the lower Tamiami aquifer near Bonita Springs, southwestern Florida Potential for saltwater intrusion into the lower Tamiami aquifer near Bonita Springs, southwestern Florida
A study was conducted to examine the potential for saltwater intrusion into the lower Tamiami aquifer beneath Bonita Springs in southwestern Florida. Field data were collected, and constant- and variable-density ground-water flow simulations were performed that: (1) spatially quantified modern and seasonal stresses, (2) identified potential mechanisms of saltwater intrusion, and (3)...

MODFLOW-2000, the U.S. Geological Survey Modular Ground-Water Model--Documentation of the SEAWAT-2000 Version with the Variable-Density Flow Process (VDF) and the Integrated MT3DMS Transport Process (IMT) MODFLOW-2000, the U.S. Geological Survey Modular Ground-Water Model--Documentation of the SEAWAT-2000 Version with the Variable-Density Flow Process (VDF) and the Integrated MT3DMS Transport Process (IMT)
SEAWAT-2000 is the latest release of the SEAWAT computer program for simulation of three-dimensional, variable-density, transient ground-water flow in porous media. SEAWAT-2000 was designed by combining a modified version of MODFLOW-2000 and MT3DMS into a single computer program. The code was developed using the MODFLOW-2000 concept of a process, which is defined as ?part of the code...
