Arc Hydro GW Data Model
Aquifer features
• An aquifer is defined by one or a set of polygon features
• Aquifer features can be grouped by HGUID
Wells
The Well location is defined as a 2D point in the Well feature class
In the Arc Hydro model we only predefine a set of basic attributes

of the spatial feature (e.g. Well)
Raster Series
Raster datasets indexed by time
Each raster represents a continuous surface describing a variable for a given time over an area of interest

Geoprocessing Tools
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
Automated Well Permitting
Calibrated regional model is imported to ArcGIS as a “baseline” model
Candidate wells are added to baseline model using well package.
Impact of new well is analyzed using MODFLOW and/or SEAWAT
Case Study #1 – Virginia DEQ
Virginia Coastal Plain Model (VCPM)
10-layer MODFLOW model used to analyze impacts of candidate wells
Criteria based on state law Potentiometric surface
cannot fall below a critical surface (80% drawdown)
Area of Impact defined by drawdown = 1 ft
Heads for layer 8
Well Permitting Workflow
Create new well update well table export well package file run MODFLOW import solution build drawdown map layer

We can build web apps for systematic application of groundwater models
Web apps result in Lower cost
Greater access
Fewer errors
Since every model is different, app must be customized for each implementation
Library of ArcGIS/AHGW geoprocessing tools provide the foundation for building apps in an economic fashion

1. Enhance cyberinfrastructure facilities
2. Enhance access to data- and computationally-intensive modeling
3. Advance high-resolution multi-physics watershed modeling
4. Promote STEM learning and water science engagement
Goal is to provide and use these tools to enhance the capacity for water resource planning and management in the Utah-Wyoming region
