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

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

Arc Hydro GW Data Model

Wells and 3D data

3D data is referenced along the well From depth (top) – To depth (bottom)

From

To

3D features (BorePoints and BoreLines)

Combining the well geometry (x, y) and the vertical measurements we can describe a set of 3D geometries (x, y, z)
