Delft-FEWS vision 2025

Delft-FEWS users are a global community

Did you know that Delft-FEWS is used in nearly 70 countries? We've put together a map of applications worldwide, dating all the way back to the very first system in 1999. While most applications are for flood forecasting, you'll see that Delft-FEWS is also used regularly for reservoir and hydropower management, drought and water quality forecasting, groundwater modelling, navigation, and more. Please help us keep it up-to-date by sending us information about your system!
