GMS:What Is GMS

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.). The GMS interface is developed by Aquaveo, LLC in Provo, Utah.

GMS was designed as a comprehensive modeling environment. Several types of models are supported and facilities are provided to share information between different models and data types. Tools are provided for site characterization, model conceptualization, mesh and grid generation, geostatistics, and post-processing.

Modules

The interface for GMS is divided into twelve modules. A module is provided for each of the basic data types supported by GMS. As you switch from one module to another module, the Dynamic Tool Palette and the Menus change. This allows you to focus only on the tools and commands related to the data type you wish to use in the modeling process. The following modules are supported in GMS:

TIN Module

Borehole Module

Solid Module

2D Mesh Module

2D Grid Module

2D Scatter Point Module

3D Mesh Module

3D Grid Module

3D Scatter Point Module

Map Module

GIS Module

UGrid Module
