The project

Four influential trends are leading to drastic changes in the modelling of water systems: the explosive increase in freely available data, the integrated modelling of river basins, interactive modelling and open-source communities. Deltares is responding by developing the next generation of hydro software, Delft3D Flexible Mesh.

Delft3D Flexible Mesh integrates five software packages (Delft3D, Simona, DUFLOW, SOBEK-RE and SOBEK-RUR) in a single suite. The development of the new software took five years and it was launched officially at the Delft Software Days in October 2015.

Our role and the results

Hydro modellers can use Delft3D Flexible Mesh to visualise entire catchments from spring to sea. In other words: where a 1D model used to be used for the river, a 2D model for the flood plains and a 3D model for coastal waters, one model is now enough. This results in a clearer, and more in-depth, picture. The software includes modules for the simulation of flows, water quality, morphology, waves, real-time control and drainage. New technology has opened up the way to a flexible mesh that allows the visualisation of complex geometries.

The Delft3D Flexible Mesh is seen as a leading product both at home and abroad, and it is used on projects worldwide. Deltares has a community platform to support users. The community, which consists of more than 10,000 members worldwide, shares experience, models, codes and scripts. The open and modular design means they can team up to work on the new generation of hydro software!

With the new software, we can model water easily and completely anywhere in the world and look at different factors simultaneously: from flood risks to water quality.

The Delft3D Flexible Mesh suite makes it possible to connect different types of models together and to set them up flexibly so that Rijkswaterstaat can do its job better with fewer models.
