Description	MODFLOW - EPA Problem Set is a Manual of Instruction Problems that addresses the principles of ground-water flow modelling and the modelling options associated with MODFLOW. It provides a series of twenty problem sets which illustrate by example the use of MODFLOW including modelling principles, input/output specifics, available options, rules of thumb, and common modelling mistakes. For each problem, the manual presents a problem statement and set-up, input data sets, model output, and a discussion of results. Model input data sets and output files are included on the accompanying disks. Specific issues addressed in the manual include radial flow to a well, anisotropic conditions, artisan-water table conversion, steady-state simulations, grid and time-stepping considerations, transient calibration and prediction, representation of aquitards and leaky aquifers, solution techniques and convergence, head dependent (third-type) boundary conditions, cross-sectional simulations, application to a water supply problem, and application to a hazardous waste problem. All of the packages in MODFLOW are utilised at least twice in the series of problems. It may be used as a self-study guide, or as a text for ground-water modelling courses. It can also be used to verify correct installation of the MODFLOW code on a particular computer system. The data sets are provided in a form ready-to-run with the IGWMC version of MODFLOW and can be edited in IGWMC's PREMOD pre-processor. They also can be used without modification with most of the commercially available versions of MODFLOW. The MODFLOW program and documentation must be purchased separately.
