SUMMARY OF CHANGES IN RIVERWARE PATCH RELEASE 9.5.5
Released November 4, 2025
Diversion Object: Pumping Energy Calculation was Incorrect
An issue, filed as RW-7231, was identified and fixed for a Diversion object using the Diversion Pump Energy category and Energy Equation and Cost user method. In this method, the computation for Energy Consumption was off by a factor of 3600 due to using seconds instead of hours. The resulting Total Energy Cost was also incorrect.
New Flow Units for Gallon Per Minute
The following flow user units were added, representing gallons per minute: All three have the same conversion factor.
RiverWare Issues
The following issues were addressed:
7227: The reservoir Predictor-Corrector Salt method failed if Storage and Inflows were zero.
7228: A crash occurred when opening a model after opening the Initialization Rules set editor.
7230: In addition to the RiverSMART issue described below, the following RiverWare issues were fixed as part of this bug:
  • The distributed MRM controller assumed that RDF files had a suffix of ".rdf".
  • The distributed MRM controller was incorrectly detecting and quoting white space in file paths.
7231: Diversion Energy Consumption was incorrect. See the note above.
7232: Running a simulation deleted Series Slot Notes when the series slot had no input values.
7233: A crash could occur when running a model with the Note Manager open.
RiverSMART
The following issues were addressed:
7230: Using Iterative MRM in RiverSMART, an internal error was issued when trying to combine RDF files.
