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 Wells in the Edwards Aquifer Point dataset Well HydroID HydroCode LandElev WellDepth AquiferID AqCode HGUID FType
Time series views create graph Well HydroID = 2791 FeatureID of the time series = HydroID 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 1991 1992 1993

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

Summary Key Points 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
