Since its introduction in 2002/2003, the current generation of the Delft-FEWS operational forecasting platform has found application in over forty operational forecasting centers worldwide. The platform is used to link data and models in real time and to produce forecasts on a daily basis. In some cases it forms a building block of a country-wide national or even international forecasting system using distributed client-server technology. In other cases it is applied at a much smaller scale on a simple desktop workstation, providing forecasts for a single basin. The flexibility of the software in open integration of models and data has additionally appealed to the research community and year-on-year hundreds of features are added.
Delft-FEWS provides an open shell system for managing forecasting processes and/or handling time series data. Delft-FEWS incorporates a wide range of general data handling utilities, while providing an open interface to any external (forecasting) model. The modular and highly configurable nature of Delft-FEWS allows it to be used effectively for data storage and retrieval tasks, simple forecasting systems and in highly complex systems utilizing a full range of modeling techniques. Delft-FEWS can either be deployed in a stand-alone, manually driven environment, or in a fully automated distributed client-server environment.

- Capable to handle large datasets of scalar, profiles, grids, ensembles
- Model independent: clear interface between Delft-FEWS and models (testable), which resulted in the development of the Delft-FEWS Published Interface (XML with XSD schema’s)
- Only develop Forecaster GUI, no GUI for system configuration, which resulted in the introduction of XML for configuration
- Client-Server communication works with PSTN, ADSL and Intranet through (at that time Java Messaging Service; replaced in 2018 by communication through the database)
- Use off-the-shell components, libraries when possible
