Description

DelftFEWS is a software platform for real-time operational forecasting systems in the hydrological, hydraulic and water quality domain. Operational water management agencies around the world deploy over 40 simulation models in manual and automated time series processing workflows to produce real-time forecasts information with DelftFEWS. DelftFEWS has also been used outside the scope of real-time applications in studies requiring execution of workflows composed of long term simulations and statistical postprocessing tasks. DelftFEWS has not specifically been designed for this purpose and does not intend to be a generic scientific workflow tool similar to e.g. Kepler. However, it offers features which make it, under some conditions, a useful production environment for scientific workflows where a chain of time series are being manipulated by generic (spatial) time series handling operations and dynamic simulation models. Data that cannot be represented as a (spatial) time series cannot be properly accommodated by the system. DelftFEWS is not a suitable environment for discovery types of workflows as its architecture, workflow composition process and its graphical user interface do not offer suitable facilities for the user.
