Dynamic Digital Twin for sewerage and flooding

Innovation update! Together with Nelen & Schuurmans we developed a Hydrodynamic calculation model in a 3D Dynamic Digital Twin

The project Dynamic Digital Twin for Sewerage aims to develop a dynamic 3D model for urban water management. In order to make this 3D model easily accessible for the entire sector, open standards are used as much as possible.

With the GWSW (Urban Water Data Dictionary) to CityGML (Data Model for the representation of urban objects in 3D) converter, it has recently become possible to present sewerage data in 3D. The project has now reached the next milestone: the integration of a hydrodynamic 3Di calculation model in a 3D Dynamic Digital Twin.

GWSW is an open standard for unambiguous exchange and disclosure of data in urban water management. This open standard improves cooperation between the administrator and the user of the sewerage data. This also makes it easier to draw up a hydrodynamic calculation model (such as 3Di). The water manager can rely on a good interaction between the surface and the underground sewage system.

All participating municipalities (Breda, The Hague, Groningen and Rotterdam) can now build a hydrodynamic calculation model according to the GWSW standard.

In recent months, Nelen & Schuurmans and Future Insight have been working on a 3Di plug-in that makes it possible to count on high resolution water within a 3D Digital Twin. With the plug-in, the integral calculation model is called on the 3Di server. The user can choose a rainfall event as desired and start the simulation. The result is the water depth which is refreshed per time step.

“Performing these simulations within a 3D Digital Twin makes the impact of flooding in urban areas even more transparent”
