Good day! Im Bryan Allan Talisay from Philippines. I deal with flood modelling and hazard mapping.
I have encountered this error when creating basin model in GeoHMS 10.1 and ArcMap10.1. Is there any solution to this problem?
Are you working over a network? Take a look at this Thread Mark Boucher seems to be familiar with ArcHydro. You could contact him if that thread does not help.
