Why MODFLOW with GMS?

Advanced three-dimensional groundwater modeling
with MODFLOW and GMS

Dedication to MODFLOW support

  • All versions of MODFLOW supported: 2005, 2000, 96, 88
  • Many MODFLOW packages supported including: DRN1, DRT1, EVT1, ETS1, GHB1, HFB1, LAK3, MNW1, RCH1, RIV1, SFR2, STR1, CHD1, WEL1, UZF1, BCF6, LPF, HUF, GMG, SIP, PCG2, SOR, SAMG and more to come
  • Guaranteed to read any model that MODFLOW can run
  • Support for MODFLOW related packages such as MODPATH, MT3DMS, RT3D, PEST, and built in ZONEBDGT tools
  • Full suite of manual and automated calibration tools including PEST, Parallel PEST, Monte Carlo simulations, calibration targets, plots and charts
  • Large model support (grid cells, stress periods) with smart memory management and caching for maintained responsiveness
  • Transient data support in real date/time format
  • Interpolation of transient data
  • Stochastic Simulation tools including Monte Carlo, Latin Hypercube, Gaussian Field, T-PROGS (better than indicator kriging) and Risk Analysis wizard for capture zone and transport analysis.

Full 3D visualization

From cross-section editing to advanced probability statistics, GMS offers unparalleled subsurface modeling tools.

  • Real time panning, zooming and rotating in 3D
  • Optimized OpenGL graphics for improved hardware rendering
  • Texture mapping of images on surfaces
  • Transparency of contours, texture maps, surfaces, iso-surfaces
  • Light source and specularity
  • Cut away views to see the inside
  • 3D cross sections at any angle
  • Iso-surfaces
  • Create animation videos - create fly-bys, animate transient data, moving cross sections

Conceptual modeling

Discover the power and capabilities of MODFLOW & GMS with a free 2-week trial. Visit the Download Center for the latest full installation of GMS. Included in the installation are a collection of GMS and MODFLOW tutorials.

The MODFLOW tutorials provide step-by-step instructions for:

  • Grid independent representation of model features using GIS type objects (points, arcs and polygons)
  • Grid independent representation of stratigraphy using solids
  • Grid independent representation of stratigraphy using point data and interpolation to MODFLOW layers
  • Display of background images of maps, aerial photos etc.
  • 2D and 3D interpolation and geostatistics including kriging

GIS integration

  • Tight integration with GIS data
  • Open Geodatabases and Shapefiles directly in GMS
  • Export Geodatabases and Shapefiles
  • Integration with Arc Hydro Groundwater for powerful report and map generation inside ArcMap
  • Worldwide global projection support including Cartesian and geographic (lat/lon)

User friendly interface

  • Standard, intuitive, user-friendly windows interface
  • Annotation tools for report generation
  • Many step-by-step tutorials
  • Complete help system
  • Active forums with contributions from users and developers
  • Full phone and email tech support
  • Regularly scheduled training courses with expert modelers. On-site training available
