3. DESCRIPTION OF PROGRAM OR FUNCTION

FE3DGW (Finite Element 3-Dimensional Ground Water) analyzes flow through large, multilayered, ground-water systems. The code has the capability to model noncontinuous as well as continuous layers, time-dependent and constant sources/sinks, and transient as well as steady-state flow.

7. UNUSUAL FEATURES OF THE PROGRAM

The code offers a wide choice of boundary conditions including prescribed heads, nodal injection or withdrawal, constant or spatially varying infiltration rates, and elemental source/sink. Initial conditions can be prescribed as vertically hydrostatic or variable hydraulic head. The heterogeneity in aquifer permeability can be described by geologic unit or explicitly for given elements. Three-dimensional elements are generated from user-defined well logs at each surface node. To facilitate interaction between disciplines, auxiliary programs are provided to plot the finite-element grid, well logs, contour maps of input and output parameters, and vertical cross sections and to determine ground-water pathlines and travel from a specified point. FE3DGW does not account for density variation and calculates only the hydraulic heads. The program can be used to support site characterization, evaluate ground-water flow rates, and estimate travel path and time in regional and local ground-water systems.
