Real-time updating and data assimilation information

DHI Comments
"Real-time updating or data assimilation are not mentioned in the
questionnaire or the general comments of the report. It has been our
experience that this process of correcting the forecast in real-time is
vital to achieving accurate and reliable information to use for making
critical decisions on flood warnings vs. flood alerts. Neither HEC-RAS
nor FLDWAV have the capability of performing this type of treatment on
the simulated data.
If you do come across a situation where you are evaluating the
performance of the flood forecasting systems and it appears that they
are not producing representative forecasts of water levels or flows,
then it may be something that could be resolved using the data
assimilation techniques available with the MIKE 11 system."
