  1. Modeling tools

  2. What is GMS? Groundwater Modeling System Computer program for building groundwater models and managing groundwater data Development partially sponsored by the U.S. Army Corps of Engineers (Waterways Experiment Station)

  3. Main Features and Capabilities Site Characterization and 3D Visualization

  4. Main Features and Capabilities, cont. 2D and 3D Contaminant Plume Mapping

  5. Main Features and Capabilities, cont. Groundwater Flow Modeling

  6. Main Features and Capabilities, cont. 20-yr Chromium Transport Contaminant Transport Modeling

  7. Conceptual Model - Site Map

  8. Feature Objects Well Point General Head Polygon River Arcs Variable Head Polygon Specified Head Arcs

  9. Grid-Based Numerical Model

  10. Telescopic Grid Refinement • The regional model can be used as a foundation for deriving local-scale models for analyzing small-scale groundwater issues • This process can be automated using custom tools in GMS

  11. Exporting Results to Google Earth Model results can be exported from GMS to Google Earth for presentation

  12. Arc hydro groundwater

  13. Arc Hydro Groundwater Data model and tools for managing groundwater data in ArcGIS

  14. What is a GIS? • Geographic Information System • Spatial Data Management • Mapping • Database • Scripting and modeling

  15. Arc Hydro GW Data Model

  16. Groundwater Analyst

  17. Arc Hydro Groundwater demo – Subsurface analyst

  18. Subsurface Analyst

  19. 3D GeoVolumes

  20. Transform GeoSections to XS2D

  21. 2D Cross Section Editing Edit cross sections in ArcMap Outcrop Borehole data Salt water interface Panel divider Panel

  22. Transform to 3D GeoSection

  23. MODFLOW Analyst • Import MODFLOW simulations • Visualization • Post-processing • Build models

  24. Simulation Feature Data Set

  25. MODFLOW Data Model

  26. MODFLOW Analyst Tools • Developed as geoprocessing (GP) tools • Classes of tools • Import • Export • Visualization/Map Layers • Model editing • Building package input • Working with transient input/solutions

  27. Import MODFLOW Model Tool INPUT OUTPUT

  28. Make MODFLOW Features Tool + Or Node2D Cell2D INPUT OUTPUT

  29. Geoprocessing Tools

  30. Geoprocessing Tools - Workflows • GP tools enable the development of workflows as models or scripts • Extendable – You can create your own workflows • Leverage low-level tools to create new tools

  31. Demo in ArcGIS Automated well permitting for the virginiadeq

  32. Summary • Model Status • Built but not calibrated • Completion target = January 2010 • Model features • Based on MODFLOW code • Numerous pre- and post-processing options available • Companion packages for particle tracking and transport • Local-scale models can be extracted from regional model • Automated workflows via Arc Hydro GW and ArcGIS • Solid foundation for ongoing water resource management in the region
