Arc Hydro Groundwater DATA MODEL

Arc Hydro GW Data Model

Framework Surface water Groundwater Temporal

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 2 D point in the Well feature class § In the Arc Hydro model we only predefine a set of basic attributes Wells in the Edwards Aquifer

Aquifer and well Well Hydro. ID = 53

Surface water and groundwater • In many cases collected and stored separately • Store, visualize, and analyze in the same context Well in the Edwards Aquifer (state well 6823302) Streamflow Gage at Comal Springs, New Braunfels Texas

Framework Temporal

Time series views – create graph Well Hydro. ID = 2791 • Feature. ID of the time series = Hydro. ID 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
