Create Hydro Network from Subwatershed
Description
Generate a hydro network (hydro edges and hydro junctions) from drainage lines, catchments, and drainage points.
- Convert the Drainage Line feature class into the Hydro Edge feature class.
- Create the Hydro Junction feature class as the From Nodes/To Nodes without duplication (a junction is defined by one and one point only)
- Create an Arc Hydro Network based on the Hydro Edge and Hydro Junction feature classes.
- Establish attribute connectivity between the drainage and network feature classes.Attribute each junction with HydroID and NextDownID field.
- Create a relationship between the Catchments and Hydro Junctions: HydroJunctionHasCatchment
