Release Notes

The release notes for HEC-ResSim 4.1.0 can be found here.


Model Linking

  • Improvements made to the "Get Linkages From" Option in the Model Linking Editor for HEC-ResSim. The "Use Existing ResSim Linkages" will overwrite the current linkages with the pathnames contained in the HEC-ResSim - Default variant. This is helpful if the user makes an update in the base HEC-ResSim alternative and needs to update to new DSS pathnames. 

New Features

  • New OSI Table Fill Options
  • New On-The-Fly (OTF) Fill Editor
  • New Observed Data addition in the OSI Variable Editor
  • In situations where multiple HEC-ResSim alternatives are present in a Forecast, the active HEC-RTS Forecast Run (checked box in the Forecast Window) now is synced with the Active HEC-ResSim Alternative.
