# Run from Delft-FEWS

Wflow integrates easily as part of an operational system by linking to the Delft-FEWS platform. Delft-FEWS integrates data and models, and is for example used in many active flood forecasting systems around the world.

This can be done without a model adapter that provides the interface between Delft-FEWS and an external model (or module). This is possible because time information in the TOML configuration file is optional and Delft-FEWS can import and export NetCDF files. When time information is left out from the TOML configuration file, the starttime, endtime and timestepsecs (timestep) of the run is extracted from the NetCDF forcing file by Wflow.

To indicate that a Wflow model runs from Delft-FEWS, the following setting needs to be specified in the main section of the TOML configuration file:

fews_run = true                         # optional, default value is false

This ensures that Wflow offsets the time handling, to meet the expectations of Delft-FEWS.
