Aquifer features An aquifer is defined by one or a set of polygon features Aquifer features can be grouped by HGUID

Wells in the Edwards Aquifer 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

Aquifer and well Well HydroID = 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 FeatureID of the time series = HydroID of the spatial feature (e.g. Well) Well HydroID = 2791

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
