Presentation Transcript

  1. MODFLOW Data Model An extension of the Arc Hydro Groundwater Simulation feature dataset

  2. MODFLOW Data Model • Data standard for storing MODFLOW models in a GIS database • Importing models built externally • Archiving calibrated models • Building new MODFLOW models inside ArcGIS • Custom scripts for analyzing/modifying models can be developed as geoprocessing tools

  3. Simulation Feature Data Set

  4. Boundary Polygon J I

  5. Cell2D and Node2D Features Cell2D Node2D

  6. Arc Hydro Groundwater WPCGmP Cell3d animation

  7. MODFLOW Data Model

  8. MODFLOW Analyst

  9. 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

  10. Import MODFLOW Model Tool INPUT OUTPUT

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

  12. Map Layer – Computed Head

  13. Build Package Input • Discretize: • Spatial • Polygons  K zones (overlay) • Points  K values (interpolate) • Polylines  River cells • Points  Wells • Temporal • Time Series  Stress Periods

  14. Discretization of Features

  15. MODFLOW Array from Polygons

  16. Geoprocessing Tools

  17. Geoprocessing Tools

  18. 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
