MINEDW is a three-dimensional (3D), finite-element, groundwater flow program that was developed specifically for mining applications but can be used in a wide-range of water resource applications. MINEDW is used worldwide to design dewatering or depressurization systems, predict local and regional environmental impacts of mine dewatering, assist in the design of water-supply systems, simulate the infilling of a pit lake after mining ceases, and estimate pore-pressure distributions within pit highwalls for geotechnical design purposes. Its user-friendly graphical interface with pre- and post-processing functionality provides a powerful numerical modeling framework.

Originally developed from FEMFLOW3D, MINEDW was validated by Sandia National Laboratories in 1998 and has been used at more than 75 mines worldwide in diverse hydrogeologic and climatic conditions. MINEDW includes 3-D graphic representations of geology, model domain, pit geometry, groundwater heads, and pore pressures; Simulates excavation and subsequent pit-lake infilling to represent different mining schedules; Simulates interaction between groundwater and surface water; Simulate long-term closure and groundwater recovery.
