wflow is Deltares’ own distributed hydrology modelling platform which maximizes the use of earth observation data and calculates all hydrological fluxes at any given location and time step, using physical parameters and meteorological input data.

The 2019 user day is for hydrological and environmental modellers who want to learn about wflow as well as for existing users. The day will cover the latest developments and features and the practical applications realized in the last year. And, by popular demand, the hands-on wflow session is back. The session gives users a chance to explore the framework and talk to the development team.

The wflow framework is an open source framework, based on Python and PCRaster languages. This structure allows users to build their own models from (open) global data and combine different modules. Major processes that can be included are snow and glacier melt, interception, soil moisture, runoff generating processes, sediment transport and river flow. This flexible modelling framework is being used around the world to simulate river flows for flood forecasting, flood risk analysis, water allocation modelling and water quality analysis. Its soil moisture module is providing valuable input for drought analysis and slope stability modelling.

Users can choose from a multitude of conceptual modules within the framework including: HBV, gr4, w3ra, sphy, pcrglobwb, FLEX-Topo and SBM. It also has been successfully coupled with MODFLOW, Delft-FEWS platform, SOBEK 2 Suite, Delft3D FM Suite and RIBASIM.
