Presentation transcript:

There are 116 Drainage Points, Drainage lines and Catchments. This is the number of features in the DrainagePoint, DrainageLine and Catchment feature classes respectively obtained from examining the attribute tables. These numbers are all the same because there is a one to one correspondence between drainage points, lines and catchments. The graphic above excerpts information from the Catchment, DrainageLine and DrainagePoint feature classes created by the ArcHydro tools. Note that each feature has a unique HydroID. Note also that the DrainID field in the DrainageLine and DrainagePoint feature classes cross references to the HydroID of the Catchment that these features drain. Missing in the Catchment feature class attribute table is a JunctionId field that should link each catchment to its downstream junction. This is present in the ArcHydro design (Maidment, 2002, ArcHydro, p85) but not implemented in the current version of the tools.
