HyperLink GroundWater Desktop
Environmental Data Analysis and 3D  Visualization

Version 4
Skip Navigation Links

GroundWater Desktop (GWD) is a 3D User Interface for visualizing and analysis of:

  • Groundwater models and their results. While GWD is general, and might be used to visualize any model, its development to-date has focused on MODFLOW, MODPATH and MT3D, including the latest unstructured grid capabilities encompassed within MODFLOW-USG.
  • Latest mayor additions in version 4 include support for Modflow 6 and mod-PATH3DU. 

  • mod-PATH3DU support includes creating input files, particle starting locations, visualization of pathlines, 3D capture zones simulations.
  • Environmental data such as water levels and chemistry, well boring and various basemap data types including Rasters, GIS shapefiles, and Images.
  • GWD provides powerful unique 3D kriging capabilities with an option to do kriging directly on Modflow grid and use of MT3D output as an external drift.
  • BIOSCREEN. BIOSCREEN-AT3D uses an exact analytical solution for transport from a patch boundary condition with time varying concentration developed by Chris Neville from SSPA. The solution considers the following transport processes: advection, dispersion, sorption, and first-order transformation reactions. Enhancements include: use of exact analytical solution, 3D simulations and multiple sources with several types of inflow concentration.
  • KT3D_H2O is a program for kriging water levels using Hydrologic Drift Terms. Implemented in GWD, KT3D_H2O combines various programs to generate gridded maps of water level elevations with an option to use several drift types, together with approximate particle tracks and capture zones
  • Share your visualization files with colleagues and clients using a freely-available restricted-capability version of the same program as a free 3D viewer

  • Export report-quality high resolution images for presentations or reports

  • Create high resolution animations

  • Capabilities can be customized to meet project-specific needs

  • Technical support available directly from the developer
