AHGW tools will enable you to take advantage of the ArcGIS platform to archive, manage, and visualize your groundwater information with
Groundwater Analyst, Modflow Analyst, and Subsurface Analyst.
Argus Open Numerical Environments (Argus ONE) - A finite-element and finite-difference numerical preprocessor providing a unified modeling solution for groundwater models
EnviroScape is a diverse collection of portable, hands-on table top models including non-point source pollution watersheds, hazardous materials, wetlands, landfill, riparian, coastal and groundwater.
GMS supports both finite-difference and finite-element groundwater models in 2D and 3D including MODFLOW 2000, MODPATH, MT3DMS/RT3D, SEAM3D, FEMWATER, PEST, UTEXAS, MODAEM and SEEP2D.
Seer3D - This software package (formerly called 3D Master or 3D Groundwater Explorer) provides for three-dimensional visualization and animation of data from groundwater flow and transport models. The current version of 3D Master uses any native MODFLOW 88/96/2000 input files or models created by PMWIN.
