Overview

With the ability to simulate groundwater and surface water interactions, and the added capability of calculating changes to groundwater chemistry, groundwater professionals now have a complete set of tools necessary for addressing water quality, groundwater supply, and source water protection initiatives.

SEAWAT v.4 - the latest USGS modeling code designed to address 3D variable-density groundwater flow coupled with multi-species solute and heat transport
MODFLOW-2000 - World standard for groundwater flow simulations
MODFLOW-2005 - three-dimensional finite-difference groundwater-model, 2005 version
MODFLOW-NWT- a Newton Formulation for MODFLOW-2005
MODPATH - standard package for forward and reverse particle tracking
Zone Budget - for sub-regional water budget calculations
MT3DMS - for multi-species contaminant transport simulations
MNW (Multi-Node Well) - designed to help simulate wells with well screens that span multiple layers.
RT3D - for reactive transport simulations
PHT3D – a multi-component transport model for three-dimensional reactive transport in saturated porous media. It couples the two existing and widely used computer programs, the solute transport model MT3DMS and the USGS geochemical code PHREEQC-2.
MGO - for determining the optimal well pumping and/or injection rates at one or more wells, in order to achieve a specific objective while maintaining reasonable system responses.
VMOD 3D-Explorer - 3D visualization and animation
WinPEST - automated calibration and sensitivity analysis
GMG (Geometric Multi-Grid) Solver Integration - latest USGS solver designed to optimize memory usage and reduce model run times
Stream Routing Package - suited for simulating the effects of surface water/groundwater interactions Lake Package (LAK3) - simulate lakes and how they interact with the aquifer within your model Evapotranspiration Segments (ETS1) Package - simulate evapotranspiration using a user-defined relation between evapotranspiration rate and hydraulic head.

Add-on software

Hydro GeoBuilder - Hydro GeoBuilder prepares a wide-range of output data for Visual MODFLOW within a single modeling environment for simulating your groundwater and surface water interactions.
MODFLOW-SURFACT - Three-dimensional finite-difference variably-saturated flow or soil vapor flow simulations (supports flow only)
MT3D99 - an enhanced version of MT3DMS, that includes support for implicit solver, TVD Solution scheme, dual-porosity advection-diffusion, Non-equilibrium Sorption and Monod Kinetics, and Multispecies Reactions, including First-Order Parent-Daughter chain reactions, and Instantaneous Reactions among species.


With Visual MODFLOW Pro, you have all the tools necessary to:

• Graphically assign model grids, properties and boundaries
• Visualize model input parameters (2D or 3D views)
• Run the flow, pathline, and transport simulations
• Automatically (WinPEST) or manually calibrate the model
• Display and interpret the modeling results in full 3D
• Produce professional reports

Visual MODFLOW Pro Product Details Overview

About The Interface	Specifically designed to increase modeling productivity and decrease complexities typically associated with building three-dimensional groundwater flow and contaminant transport models. The interface is divided into three separate modules; Input, Run and Output.
Building The Model	Logical structure and layout eliminates the difficulties of building the input data file for a groundwater flow and/or transport model by guiding the user through the sequence of steps necessary to build a model.
Running The Simulation	Allows the user to select and modify the various flow and transport run-time options and start the model calculations using the Win32 MODFLOW Suitedirectly from within the modeling environment.
Power Features	Visual MODFLOW Pro has multiple power features including: USGS SEAWAT v.4 MGO - Modular Groundwater optimizer GMG Solver Implementation MNW – Multi-Node Well
Displaying And Interpreting Results	Visual MODFLOW Pro automatically reads the results created from each successful simulation and provides a comprehensive selection of graphical formats for displaying full-color results in plan view and cross-sectional views.
Calibrating The Model	An extensive selection of built-in model calibration plots and statistical summaries give you with all the interpretation capabilities you need to properly and thoroughly analyze the model calibration data.
