Computational Framework

Update 2022: 
A lot of developments for Computational Framework and applying the new what-if concept in client-server applications have been implemented in 2022. Interaction with the Open Archive and extending the types of supported modifiers can be added to this list as well. A table modifier for multi-value attributes can now be used and a widely used type in the ‘legacy’ what-if concept – the typical profile modifier – can now also be applied within the new what-if approach. A series of usability improvements have been implemented as well. Mostly applicable to the client-server forecasting systems, the creation and (auto) approval of what-if scenarios have been simplified. Since modifiers can also be used in the regular (classical) fashion, the relevant displays (Modifier Display and What-if Editor Display) clearly distinguishes in what kind of modifiers users are creating using these displays. A number of configuration blueprints have been developed as well. As part of the HydroMT automatic model building process, users can generate Delft-FEWS computational framework configuration for wflow and D-Emission/Delwaq (in combination with wflow). 


Plan 2022

The Computational Framework is the mode of Delft-FEWS to run scenarios which are not strictly connected to the 'here & now' like in operational forecasting systems. You can define and run scenarios in the (far) past or future, visualize, compare and manage them.

These scenarios allow combination of properties with the existing modifiers concept to allow input changes in models, external boundary conditions, model/parameter settings etc. The scenarios are organized in the IFD-tree and can be managed in the new WhatIfEditor-display using the new what-if templates concept of Delft-FEWS. Scenario results can be viewed by selecting the scenario in the IFD-tree.

  • In 2022 we are focusing on the final developments creating, running and managing these scenarios, like:

  • Improved interaction of the Computation Framework with the Open Archive (to search and retrieve results based scenario identification)

  • Exchange what-if scenarios between users

  • Extension of modifier options: multi-value attributes and typical profile modifier

  • Introducing this new what-if concept in a 'normal' operational, client-server forecasting system

  • Creation of configuration blueprints for Deltares models (Ribasim, wflow, delwaq) for quick integration into Delft-FEWS applications.

Expected effort in 2022:  ±55 days
