Time of Concentration - Not working

[PrasadDaggupati]

Dear all,

I am trying to run the time of concentration tool in Archydro 1.4 in ArcGIS 9.3 and I get the below error. I am using ArcHydro tutuorial data and calculated the slope myself as it was not given in the tutorial data.

Executing: ComputeTimeofConcentration Catchment TR55zone fdr Divide_slope1 yr2hr24prec manningsn paved D:\deleteme\Ttgrid D:\deleteme\Longestflowpath1 HydroEdge

End Time: Thu Sep 15 12:06:27 2011 (Elapsed Time: 1.00 seconds)

I also tried it in ArcGIS10 with ArcHydro 2 and still I have similar error. Anybodys help on this error and how to fix it would be greatly appreciated.

Thanks,
Prasad.

Dear Prasad,

I am also getting the same error when I am running the longest flow path tool in Hec-GeoHMS V5.

Did you able to fix that error?

Hi,

Usually, for errors of this type, you need to check the path of your file location, as in if it matches with the path set in APUtilities
Location.

Your output cannot be a shape file (Longestflowpath1.shp). It needs to be feature class stored in a geodatabase.
