Delft3D Modelling Guidelines

Delft3D is a world leading open-source 2D/3D modeling suite to investigate hydrodynamics, sediment transport, morphology and water quality for fluvial, estuarine and coastal environments. The software is applied and has proven his capabilities on many places around the world, like the Netherlands, USA, Hong Kong, Singapore, Australia, Venice, UAE, etc. The software is continuously improved and developed with innovating advanced modelling techniques as consequence of the research work of our institute and to stay world leading.

The experience and feedback from starting modellers is that they can learn how to handle the buttons in the user-interfaces from the manuals, but they lack knowledge on the required steps in the modellling process as well as more practical choices they have to make when setting up a Delft3D model. Things like what should be the grid resolution, how to derive boundary conditions and what processes or parameters are important in which situation. The present software packages provide an overflow of options, while certain combinations of options can lead to unrealistic model outcome. These modelling guidelines are meant to support this process.

These modelling guidelines are meant to provide and share knowledge so that new users are not tempted to invent the wheel again. They may, preferably, focus their minds on new areas. The guidelines discuss several approaches to Delft3D modelling in coastal areas, rivers and lakes and provide several tips and tools to make life easier. Hence, these guidelines will not tell you how to use the buttons in the user-interfaces; we refer to the comprehensive manuals for each module of Delft3D.
