Background
What is Arc Hydro?
Data models (geodatabase designs): Best GIS practices in a specific field. Terminology, common language. Standard.
Tools – surface water, groundwater. Community – user community advances best practices.

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

TimeSeries - Tabular structure for storing time series values indexed by time, location, and variable. FeatureID of the time series = HydroID of the spatial feature (e.g., Well).

Combining the well geometry (x, y) and the vertical data stored in the BoreholeLog table we can describe a set of 3D geometries (x, y, z)

From the tabular data we create 3D features that can be viewed in ArcScene.
