GMS (GROUNDWATER MODELLING SYSTEM)
The Groundwater Modeling System (GMS) is a comprehensive groundwater modeling environment. GMS provides GIS based graphical preprocessing tools to automate and streamline the modeling process. GMS interfaces with MODFLOW and several other standard groundwater models, and provides advanced graphical features for viewing and calibrating model results. With thousands of users at U.S. and foreign government agencies, private firms, and universities, GMS has proven to be the modeling system of choice for groundwater professionals.

GMS provides tools for every phase of a groundwater simulation including site characterization, model development, calibration, post-processing, and visualization. GMS supports a number of finite-difference and finite-element models in 2D and 3D including MODAEM, MODFLOW 2000, MODPATH, MT3DMS, RT3D, SEAM3D, FEMWATER, PEST, SEEP2D and UTEXAS.
GMS can be used for a number of modeling applications including site visualization, aquifer resource studies, well field management and permitting, site contamination evaluation and cleanup, natural attenuation and bioremediation, as well as seepage and slope stability.

Features and benefits
The Groundwater Modeling System (GMS) is a comprehensive graphical user environment for performing groundwater simulations. The entire GMS system consists of a graphical user interface (the GMS program) and a number of analysis codes (MODFLOW, MT3DMS, etc.). GMS is used as a preprocessor to graphically create numerical models, and as a post processor to import and visualize model results
GMS uses a Conceptual Modeling Approach to create and manage numerical models using GIS based objects. Other powerful GMS features include 3D Model Conceptualization, Site Visualization, Advanced Geostatistics, Automated Calibration, Stochastic Modeling. GMS also has advanced tools for Data Import, Data Export and data Visualization and Animation. (leave room for images)
GMS Annual Maintenance Program
We strongly recommend that you subscribe to the annual maintenance program when you purchase GMS. The program provides you with the following benefits:
- Upgrades and patches free of additional charge.
- A telephone ‘hot line’ support service from which you can obtain advice on issues related to the use of GMS
Membership of the program is optional. The fee to join the program is calculated as 15% of
the software purchase price.
If you choose not to join, then support will be charged on a ‘per-instance’ basis at £65 per hour. A minimum charge of £15 is applicable for all calls. Software upgrades are charged at 70% of the standard software price.
If you currently have GMS v6.0 licenses, you only need to pay the 15% annual maintenance fee to upgrade to version 6.5. If you currently have older versions of GMS, you will first have to upgrade your license to GMS v6.0 at current upgrade fees, and then pay the 15% annual maintenance fee (contact us for details).
