The start data or time is invalid

Recommended Posts


I am trying to do the tutorial of HEC-HMS, once I saved the HMS file, the error message comes up as "The start data or time is invalid", where the problem may be?

Check your start date in the HMS job control settings in WMS.  Also if you have defined dates for your precipitation data, make sure these are correct and correspond to the start date in your HMS Job Control.  I'd always use the Hydrologic Modeling Wizard to set these parameters when setting up an initial HMS model using WMS.

Let me know if you continue to have problems.
