Issue with Hydroflow Hydrographs in Civil 3D 2019

[Anonymous]

Hello,

I’ve been using Civil 3D 2018 for about a year (upgraded to 2019 a few months ago), and have had problems with the Hydroflow Hydrographs (HH) program contained within.  I have been using HH for several years to design or analyze storm water detention ponds, and I have a pretty good feel for the results I should be getting.  I don’t see a problem with the peak flows for a sub-basin that are computed through development of hydrographs; the problem I am experiencing occurs within the process of routing the hydrograph through the detention pond.  When I route a hydrograph through the pond, it provides bogus results.

I have a separate older laptop with Land Desktop 2009 and a stand alone version of Hydroflow Hydroflow Hydrographs installed on it that I use for storm water detention design and/or analyses.  If I didn’t have it, I would be stuck.

Has anyone experienced a similar issue that could help me with a fix?  Many thanks in advance.

I downloaded the .exe and saved it in the file location specified, tried it again, and still the same result.  The issue shown on the post your forwarded isn't the same issue as I am having.  But it was definitely worth a try.  Thanks for your help.

Hi @Anonymous. Might we see these bogus results? I'd be happy to take a look if you could provide a file.

Were you all able to solve this issue with Hydrographs 2019.  I have the same problem - bogus results from the routing.  Please update with the latest solution if you found one.  Thank you.

can you share a model that shows these bogus results?

For some reason, I've not encountered the issue recently.  The issue occurred more than once in the past, but lately has not.  I will certainly post the next time I do.
