GMS

GMS

3D groundwater modeling system

  • Groundwater software solution to develop, characterize and visualize groundwater models in a 3D environment
  • Flexible modeling
  • Data importing from several sources

 

Overview

GMS is the most sophisticated and comprehensive groundwater modeling software available! GMS provides tools for every phase of a groundwater simulation including site characterization, model development, calibration, post-processing, and visualization. GMS supports both finite-difference and finite-element models in 2D and 3D including MODFLOW 2000, MODPATH, MT3DMS/RT3D, SEAM3D, ART3D, UTCHEM, FEMWATER, PEST, UCODE, MODAEM and SEEP2D. The program's modular design enables the user to select modules in custom combinations, allowing the user to choose only those groundwater modeling capabilities that are required. Additional GMS modules can be purchased and added at any time.

Flexible modeling approaches

  • Build a conceptual model by constructing a high level representation of the model using familiar GIS objects: points, arcs and polygons.
  • Work with large, complex models in a simple and efficient manner by using the conceptual modeling approach
  • Easily update or change the model as needed.

MODFLOW
MODFLOW

MODPATH

MODPATH is a particle tracking code that is used in conjunction with MODFLOW. After running a MODFLOW simulation, the user can designate the location of a set of particles. The particles are then tracked through time assuming they are transported by advection using the flow field computed by MODFLOW.

MODPATH

MT3DMS

MT3DMS is a modular three-dimensional transport model for the simulation of advection, dispersion, and chemical reactions of dissolved constituents in groundwater systems.

MT3DMS

SEAWAT

SEAWAT is a three dimensional variable density groundwater flow and transport model developed by the USGS based on MODFLOW and MT3DMS.

SEAWAT

RT3D

RT3D is a multi-species reactive transport model developed by the Battelle Pacific Northwest National Laboratory. RT3D is a modified version of MT3DMS that utilizes alternate Chemical Reaction packages.

RT3D

SEAM3D

SEAM3D is a reactive transport model used to simulate complex biodegradation problems involving multiple substrates and multiple electron acceptors.

SEAM3D

MODAEM

Unlike finite difference and finite element models, analytic element models do not require a discretization of the problem domain. Rather the model is completely defined by boundary conditions, source/sink terms, and material property zones represented by points, polylines (arcs), and polygons.

MODAEM

UTEXAS

UTEXAS quickly analyzes dams, levees and other slopes for the critical failure surface and factor of safety. Use CAD and GIS data to quickly set up a 2D profile model, or sketch it in GMS using the easy and familiar arc and polygon tools.

UTEXAS

SEEP2D

SEEP2D is a two-dimensional finite element groundwater model developed by Fred Tracy of the U.S. Army Engineer Waterways Experiment Station (WES). SEEP2D is designed to be used on profile models (XZ models) such as cross-sections of earth dams or levees.

SEEP2D

FEMWATER

A fully 3D finite-element model used to simulate density-driven coupled flow and contaminant transport in saturated and unsaturated zones. FEMWATER allows modeling of salinity intrusion and other density-dependent contaminants.

FEMWATER

Supported Utilities

PEST & Parallel PEST

A model-independent, non-linear parameter estimator. The nonlinear parameter estimation algorithm used by PEST is uniquely robust and powerful having been developed for use with complex environmental models. The purpose of PEST is to assist in data interpretation, model calibration, and predictive analysis.

T-PROGS

The T-PROGS software is used to perform transition probability geostatistics on borehole data. The output of the T-PROGS software is a set of N material sets on a 3D grid.

SAMG Solver

GMS now has the support for the SAMG (Algebraic Multigrid Methods for Systems) mulitgrid solver for MODFLOW. SAMG is the most efficient solver available for use with MODFLOW. Depending on the application and problem size, the computational cost can be reduced by one to two magnitudes.

System requirements

  • Operating Systems
    • Windows XP (limited support)
    • Windows Vista
    • Windows 7
    • Windows 8
  • RAM: 1 GB (8 GB or more recommended)
  • CPU: GMS software is CPU intensive. We recommend the fastest CPU your budget allows. A multi-core CPU may be useful for multi-tasking while GMS is running. However, GMS software does not use more than a single core at this time, so a faster dual core may provide better performance than a slower quad core CPU.
  • Graphics Card: For all display features to be enabled, OpenGL 1.5 must be supported. We recommend NVIDIA® Quadro® based graphics cards because of their superb OpenGL support. The use of a dedicated graphics card is strongly recommended. Integrated graphics cards are often problematic.
  • Display Resolution: 1024 x 768 or greater
