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
