Groundwater models utilize sophisticated computer programs, or codes, to solve complex problems involving recharge, discharge, wells, drawdown, and groundwater-surface-water interactions. Numerous such codes exist. MODFLOW, a model developed by the U.S. Geological Survey, is considered an international standard for groundwater modeling and is one of the most widely-used groundwater codes.
