Watersheds

Streams
The Arc Hydro Framework is a simplified version of the full Arc Hydro data model designed for an entry level user who just wants to put together a basic data set for streams, watersheds, waterbodies and hydro points like stream gages and water quality monitoring points
Hydro Points

4. Arc Hydro Framework Data Model
The Arc Hydro framework is built on a Hydro Network made up of HydroEdges (stream lines) and HydroJunctions (points of interest on the lines). The watersheds, waterbodies and hydropoints are connected to the hydronetwork using relationships with the hydro junctions (blue lines in the diagram).

7. Operations Decision Support System
A WCU is a body
of water that is
surrounded by
control structures
Goal of the Operations
Decision Support System:
to control the
hydraulic head
and water flow
in water control units
(WCU’s)
in a satisfactory manner
