MODPATH is a particle tracking

code that is used in

conjunction with MODFLOW.

simulation, the user can

designate the location of a set

of particles. The particles are

GMS provides a custom interface to the MODPATH model offering a simple way to set model

parameters and a graphical user interface to run the model and visualize the results. Gather

background data from a variety of sources from GIS to CAD and access online data from

numerous databases of maps, images, and elevation data. GMS allows you to interact with

models in true 3D taking advantage of optimized OpenGL graphics and to create photo -realistic

renderings and animations for PowerPoint, print, and web presentations .

MODPATH was developed by the U.S. Geological Survey. Version 5.0 of MODPATH is supported in

GMS. The version of MODPATH distributed with GMS is the original public domain version

distributed by the USGS, with minor modifications to accommodate GMS.

then tracked through time assuming they are transported by advection using the flow field

computed by MODFLOW. Particles can be tracked either forward in time or backward in time.

Because of the user-friendly interface in GMS, an intimate knowledge of MODPATH is not

required to effectively do particle tracking in GMS. Particle tracking analyses are particularly

useful for delineating capture zones or areas of influence for wells.

MT3DMS is a newer version of the MT3D model distributed with earlier versions of GMS.

MT3DMS differs from MT3D in that it allows for multi-species transport, supports additional

solvers, and allows for cell-by-cell input of all model parameters.

a modular structure similar to the structure utilized by MODFLOW. MT3DMS is used in

conjunction with MODFLOW in a two step flow and transport simulation. Heads and cell -by-cell

flux terms are computed by MODFLOW during the flow simulation and are written to a specially

formatted file. This file is then read by MT3DMS and utilized as the flow field for the transport

portion of the simulation.

RT3D is a multi-species

reactive transport model

Pacific Northwest National

Laboratory. RT3D is a modified

version of MT3DMS that utilizes

GMS provides a custom interface to the RT3D and SEAWAT models offering a simple way to set

alternate Chemical Reaction packages. Numerous pre-defined reactions are available and an

option is provided for creating user-defined reactions. RT3D is well-suited for simulating

natural attenuation and bioremediation.

SEAWAT3D Variable-density

Groundwater Flow Coupled

with Multi-species Solute &

Heat Transport

SEAWAT is a three dimensional

variable density groundwater

flow and transport model

GMS supports SEAWAT as a pre- and post-processor. The interface to SEAWAT relies on the

interface to MODFLOW and MT3DMS. The input data for SEAWAT is generated by GMS and saved

to a set of files including a MODFLOW model, an MT3D model if transport is used, and a SEAWAT

model pointing to the MODFLOW and MT3D model's package files. These files are then read by

SEAWAT and executed. SEAWAT uses the MODFLOW and MT3D interfaces for boundary condition

display and for post-processing.

developed by the USGS based on MODFLOW and MT3DMS. SEAWAT v4 is based on MODFLOW

2000 and MT3DMS 5.2. SEAWAT includes two additional packages: Variable -Density Flow (VDF)

and Viscosity (VSC).

PHT3DReactive Transport

Modeling with GMS

PHT3D is a multicomponent

transport model for three-

dimensional reactive transport

in saturated porous media.

PHT3D is a combination of

MT3DMS and PHREEQC-2. The

PHREEQC component allows for a variety of low temperature aqueous geochemical reactions.

SEAM3DReactive Transport

Modeling with GMS

SEAM3D is a reactive transport

model used to simulate complex

biodegradation problems

involving multiple substrates

and multiple electron

acceptors. It is based on the

MT3DMS code. In addition to the regular MT3DMS modules, SEAM3D includes a Biodegradation

package and NAPL Dissolution package. SEAM3D was developed by Mark Widdowson at Virginia

Tech University.

MOADEMAnalytic Element Modeling with GMS

The MODAEM model is developed by Vic

Kelson of Wittman Hydro Planning

Associates in Bloomington, Indiana. 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. Since GMS users are already in the habit of building conceptual models in the Map Module using

points, arcs, and polygons, analytic element modeling is a natural fit for GMS.

FEFLOWFinite Element Groundwater Flow &

Transport in GMS

Import and export 2D and 3D finite element

meshes into and out of GMS using the FEFLOW

ASCII Model File Format (*.fem). This makes it

possible to build a mesh in GMS and export it

so it can be used to build a model in FEFLOW.

Contaminant Transport in GMS

FEMWATER model offering a simple way to set

data. GMS allows you to interact with models in true 3D taking advantage of optimized OpenGL

graphics and to create photo-realistic renderings and animations for PowerPoint, print, and web presentations.

SEEP2DEarth Dam and Levee

Analysis with GMS

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 can be used for either confined or unconfined steady state flow models. For

unconfined models, both saturated and unsaturated flow is simulated. The phreatic surface

can be displayed by plotting the contour line at where pressure head equals zero .

Contours of total head (equipotential lines) and flow vectors can be plotted. An option is also

available for computing flow potential values at the nodes. These values can be used to plot

flow lines. Together with the equipotential lines, the flow lines can be used to plot a flow net.

GMS 10.3 System Requirements

✓ Operating System : Windows® XP (Limited support), Windows Vista®, Windows 7, Windows 8/8. 1 or Windows 10

✓ RAM : 4 GB (8GB or more recommended)

✓ CPU: GMS software is CPU intensive. We recommend the fastest CPU your budget allows.

✓ Graphics Card : For all display features to be enabled, OpenGL 1.5 or higher must be supported. The use of a dedicated

graphics card is strongly recommended. Integrated graphics cards are often problematic.

✓ Display Resolution : 1920 x 1080 or greater
