Groundwater Desktop 5.2.30 Groundwater modeling and visualization
Groundwater Desktop is a specialized software designed for the visualization, interpretation, and management of groundwater-related data. It is often used by hydrogeologists, environmental engineers, and researchers to manage, analyze, and interpret groundwater flow and contaminant transport models. The program provides a user-friendly environment for working with complex groundwater modeling codes, particularly MODFLOW, which is one of the most widely used groundwater numerical simulation tools developed by the United States Geological Survey (USGS). By integrating various modeling components into a single platform, GWD simplifies the process of creating, editing, running, and visualizing models. Users can build conceptual models, define boundary conditions, assign hydraulic parameters, and simulate flow and transport in both steady-state and transient states . 

1. Purpose and Overview
Groundwater Desktop is a single workspace for managing different types of hydrogeological information, such as:

• Borehole and well data (location, depth, lithology, pumping tests, water level)
  
• Aquifer properties (hydraulic conductivity, transportability, storage)
  
• Groundwater quality (chemical concentrations, contaminants)
  
• Modeling results from numerical simulations (e.g., MODFLOW)
  

Its main goal is to make groundwater data more accessible, visual, and analyzable by integrating GIS mapping tools with databases and modeling software. It bridges the gap between traditional groundwater modeling tools and modern spatial data visualization systems.
2. Key Features
A. GIS integration
Groundwater Desktop includes full GIS capabilities and allows users to:

• Import, display, and analyze shape files, raster maps, and network data.
  
• Overlay groundwater features (e.g., wells, aquifers, rivers) with topographic and geological maps.
  
• Perform spatial analyses such as buffering, generating contour lines, and interpolating groundwater levels.
  
• This integration allows users to visualize relationships between surface features and subsurface conditions.
  

B. Borehole and hydrogeological data management
Users can store and manage detailed borehole information:

• Lithological and stratigraphic reports
  
• Coverage and screening details
  
• Water level and pumping test results
  
• Groundwater level time series or qualitative measurements
  

Data can be displayed as borehole reports, cross-sections, or 3D visualizations, helping to interpret groundwater aquifer structures.
C. 3D visualization and cross-sections
GWD supports 3D modeling of geological and hydrogeological layers. Users can:

• Create 3D fence diagrams and block models.
  
• Visualize aquifers, wells, and pollutants in three dimensions.
  
• Interactively draw geological cross-sections based on borehole and surface data.
  
• This capability is particularly valuable for understanding subsurface conditions and for communicating findings to stakeholders.
  

D. Integration with groundwater models
One of the main advantages of Groundwater Desktop is its compatibility with numerical groundwater models, in particular:

• MODFLOW (the most widely used groundwater flow model)
  
• MT3DMS/MT3D-USGS (solute transport models)
  
• MODPATH (particle tracking)
  
• SEAWAT (Density-dependent flow and transport)
  

Users can prepare model inputs, visualize model networks, and display simulation results such as hydraulic contour lines, water level drop maps, or concentration columns directly in the GIS environment.
E. Time data management
Groundwater Desktop can manage time series data for the following:

• Groundwater level
  
• Pumping rate
  
• Rainfall and nutrition data
  
• Pollutant concentration
  

Time series graphs and animations can be produced to show changes in groundwater conditions over time.
F. Importing and exporting data
This software supports a wide range of data formats:

• GIS formats: Shapefile, GeoTIFF, ASCII grid
  
• Model formats: MODFLOW, MT3D, MODPATH input/output files
  
• Database and spreadsheet formats: CSV, Excel, Access
  

This flexibility allows for easy data exchange between GWD, modeling tools, and GIS platforms such as ArcGIS or QGIS.
