GMS is a comprehensive groundwater modeling environment with GIS based graphical preprocessing tools to automate and streamline the modeling process. GMS seamlessly interfaces with MODFLOW and several other preeminent groundwater models, and provides advanced graphical features for viewing and calibrating model results.
Features
The Groundwater Modeling System (GMS) is a comprehensive graphical user environment for performing groundwater simulations. GMS 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, and Stochastic Modeling. GMS also has advanced tools for Data Import, Data Export and Data Visualization and Animation.
What's new in GMS 7.1
The following is a list of the more significant changes in GMS 7.1
New toolbar
The new toolbar includes tools for building polygons, running models, and for the Map -> X commands where X is a geometric object or numerical model
. MODFLOW enhancements
MODFLOW MNW Package
MODFLOW HFB parameters
MODFLOW SFR parameters
Better handling of unsupported MODFLOW packages in the Name file
Model checker support for DRT, ETS and MNW packages
PEST
Support for the latest version of PEST
Parallel PEST
Now you can run PEST in parallel on your own computer to take advantage of machines with multiple cores
SVD and SVD-Assist
Now you use the Singular Value Decomposition option with PEST as well as the very powerful SVD-Assist method
UTEXAS enhancements
1. Pseudo-static analyses option support (seismic coefficient, Group K Sub-Command "SEI")
Tangent line support for starting circles
Interpolated shear strengths support
Fixed grid search support
Graphical editing of starting circle
Import of GeoStudio files
Simplified interface for GMS 2D mode
Hiding of tools and modules not in use
SEEP2D model automatically initialized from conceptual model
SEEP2D boundary conditions automatically mapped from conceptual model (no need to run Map -> SEEP2D)
Easily create all coverage types in one step
. Feature object types automatically assigned based on coverage attributes
Allow only one conceptual model
New Redraw Display command to force recreation of all the display lists
Map to existing feature polygons when doing Shapes -> Feature Objects or ArcObjects -> Feature Objects
