Models

All models are available here:

https://svn.oss.deltares.nl/repos/openearthmodels/trunk/riverlab
 

Models within the RiverLab are available according to the OpenEarth philosophy. This means that the models are stored in a Subversion system (repository), and everyone can download, adapt and upload them in such a way that all steps are traceable (and reversible). This is analogue to the way the open source software is maintained and developed. You only need to subscribe once. Here is described which steps you have to take to download, adapt, run and upload the models. On this website a basic tutorial about using the SVN-subversion system can be found.

Schematic test cases

Schematic test cases

Within the RiverLab several 1D , 2D, and 3D schematic test cases are available that are used to test all the software functionalities (hydrodynamic and morphological). These test cases are preferably based on analytical solutions or a comparison with available 2D results and can be used by the research community to test new functionalities that are implemented. A validation document is available with a detailed description of the testcases.

Real world cases

Real world cases

Real world cases can be shared within the RiverLab to be further developed by the whole community.

 

 

Model Specifications Description

Waal

 

  • D-Flow FM 1D
  • morphodynamics
This model of the Waal River is based on a recent hydrodynamic 1D (SOBEK3)-model (sobek-rijn-j17_5-v2) of Rijkswaterstaat and describes the geometry of approximately 2017. The SOBEK3-model is converted to D-Flow FM 1D and morphological information and boundary conditions are added based on the SOBEK-RE model that was used in an earlier pilot within NKWK-Rivieren (Sloff, 2006; Giri and Spruyt, 2017).

Black Volta 

  • D-Flow FM
  • Delft3D-4
  • 2D, 3D
  • morphodynamics
This model of the Black Volta is an example of 2D and 3D hydrodynamic and morphodynamic modelling. 

Pannerdensche Kop

 

  • D-Flow FM
  • 2D
  • morphodynamics
This model of the bifurcation of the Rhine River at Pannerden stems from the existing DVR model in Delft3D-4 of the entire Rhine Branches. 

Other available models

Other available models

The available 1D hydrodynamic (SOBEK3)-models of the Dutch water systems, as used by Rijkswaterstaat, can be requested from the Helpdesk Water.

Rijkswaterstaat is also setting up 2D hydrodynamic models in the new D-Flow FM software. This is still work in progress, but a pilot model of the Waal and a preliminary version of the Maas can be requested via the Helpdesk Water as well (only for research purposes). In 2019 the first 2D models for the Rhine branches and the Rhine-Muese Delta in D-Flow FM will be developed and will be provided in the RiverLab.
