Delft-FEWS 2023.01 released

Delft-FEWS Stable 2023.01 Released!

Delft-FEWS Product management proudly presents the new Delft-FEWS Stable release 2023.01!

This version of Delft-FEWS contains (again) more than 100 new features!

Explorer features and many new imports

Personalizing your startup tabs is now possible and easier alignment of your panels in the Dashboard Display has been implemented. Interesting new (spatial) transformations are included and so are more than 10 different new import routines.

Webservices and Open Archive

Many new endpoints for querying your grid plots, rating curves and ensembles have been added to the REST webservice. A new catalogue harvester based on Open Search was added to the Open Archive and the Archive Display now allows you to tag data for an event for files stored in the Archive with Delft-FEWS produced NetCDF files as well as files in the External NetCDF storage connected to your system.


Considering the increased interest in using the Topology for organizing the forecast process, new configuration options have been added e.g. to directly open a spatial plot from the Topology. Also the new What-if Editor functionality - which also uses the Topology tree - has been made more robust. A clear separation is now visible if you are working with modifiers in your day-to-day forecast process compared to ones used in your scenario work.

Web Operator Client

Last but not least, the Web Operator Client matured in this version. Although not an official product yet, it can already be tested within a Stand Alone environment with a minimum of configuration. If you are interested, reach out to

A webinar demonstrating the highlights of the Delft-FEWS 2023.01 new features is planned for September 14, 2023.
