The Delft3D FM Suite combines proven technology from the hydrodynamic engines of Delft3D 4 and SOBEK 2 and adds flexible administration. The new, advanced software will allow water managers and modelers to do their work better and faster.

SOBEK functionality in Delft3D FM Suite 1D2D

The Delft3D FM Suite 1D2D will be the aggregated successor of SOBEK-Rural and DUFLOW for irrigation and drainage systems, SOBEK-RE and SOBEK-River for river systems, and SOBEK-Urban for sewerage and urban drainage systems.

Delft3D FM Suite 1D2D is set up within the Delta Shell Framework, providing additional functionality, extensive compatibility and an intuitive user interface. The current performance (simulation time) of the prototypes of Delft3D FM with 1D-2D functionality, is matching the performance of DUFLOW and SOBEK-RE.
