problem delineation watershed in geohms

[antonio82]

i have a problem with the delineation watershed in geohms.
when i start with a "new project", geohms give me a project area that it's a bad clip to the correct watershed....
again i have notated that catchment polygons have "HydroID" and "GridID" empty.... and AdjointCatchment has not elements!!!

excuseme for my bad english!

bye Antonio

Antonio,

Did you have any luck solving your problem with GeoHMS? I am having the same error -2147220982, the object has been deleted and is no longer valid. [xxdis].
Then, when I try to create the Adjoint Catchments, it creates an empty dataset. Any guidance you can give would be much appreciated.

Thanks,
Caitlin

Try closing the ArcMap document and deleting all files in the TEMP folder (C:/.../Local Settings/temp).

To delete the contents of the TEMP folder follow the steps below.
1) Open up a Command Prompt by going to:
Start Menu, All Programs, Accessories, Command Prompt
2) Type the following, one at at time hitting ENTER after each line.
a. cd /d %TMP%
b. rd /s .

you need to use ArcHydro to populate the hydro ID field. That error is because HEC-Geo can't keep track of what values it's writing because HydroID is null.
