Ayman98 0 Posted May 17, 2016 Report Share Posted May 17, 2016 (edited) Hello When running the HEC-HMS, there are warning and errors as follows: WARNING 20657: Hyetograph gage "NAKHIEL" for subbasin "691B" contains 596064 missing precipitation values that were set to zero. WARNING 41784: Simulation time interval is greater than 0.29 * lag for subbasin "630B"; reduce simulation time interval. ERROR: 10000 Process could not be completed because of a lack of memory. Contact HEC for recommendations. - The precipitation values of the Hyetograph gage are as follows: 12/5/2001 1:00:00 AM 0.25 1/3/2002 1:00:00 AM 0.76 1/9/2002 1:00:00 AM 0.51 1/10/2002 1:00:00 AM 4.06 1/28/2002 1:00:00 AM 0.51 2/11/2002 1:00:00 AM 1.02 10/28/2002 1:00:00 AM 2.03 10/30/2002 1:00:00 AM 10.92 10/31/2002 1:00:00 AM 32.0 ** up to 2016 The time interval in the job control is 15 min How to fix these problems Best regards Edited May 17, 2016 by Ayman98 Quote Link to post Share on other sites
kcornwell 0 Posted May 24, 2016 Report Share Posted May 24, 2016 Ayman98, For WARNING 41784, you can try decreasing the time step. Usually a 30 minute time-step does not return that warning. As for the other errors, if you would be able to email Tech Support at support@aquaveo.com and include your project file, it will be much easier for us to find a solution for you.

Ayman98 0 Posted May 31, 2016 Author Report Share Posted May 31, 2016 Dear Kyle Thank you so much, I fixed all of that but I still receive this error on saving the HEC-HMS file: Unrecognized time interval (E Part) What that error means and how to fix it?

Chris Smemoe 1 Posted May 31, 2016 Report Share Posted May 31, 2016 Ayman98, The problem is that you need consistent time intervals between your precipitation values. If there is no precipitation for a certain time interval, enter a value of 0 for the precipitation. If you try to do too large a time interval between precipitation values, you may also get this error message. I'd try to keep your precipitation time interval to less than an hour, though a single value for each day might work (I don't know that I've tried it). Chris Quote Link to post Share on other sites
