intro story DELWAQ

DELWAQ

DELWAQ is the engine of the D-Water Quality and D-Ecology programmes of the Delft3D suite. It is based on a rich library from which relevant substances and processes can be selected to quickly put water and sediment quality models together.

The processes library covers many aspects of water quality and ecology, from basic tracers, dissolved oxygen, nutrients, organic matter, inorganic suspended matter, heavy metals, bacteria and organic micro-pollutants, to complex algae and macrophyte dynamics. High performance solvers enable the simulation of long periods, often required to capture the full cycles of the processes being modelled.

The finite volume approach underlying DELWAQ allows it to be coupled to both the structured grid hydrodynamics of the current Delft3D-FLOW engine and the upcoming D-Flow Flexible Mesh engine (1D-2D-3D) of the Delft3D Flexible Mesh Suite (or even other models such as TELEMAC).

'DELWAQ in open source' is our invitation to all leading experts to collaborate in further development and research in the field of water quality, ecology and morphology using Delft3D. Feel free to post your DELWAQ related questions or comments in this dedicated forum space. If you are new to DELWAQ, the tutorial (in the user manual) is a good place to start. A list of DELWAQ related publications is available here.

Grid Generation

Hello everybody!
I'm using delft3d software for my master's degree and i really need your help. I had some problems with flow, but maybe i made some errors when i realized the bathymetry, so I started from the beginning. I have the outline of an harbour and i have to make an irregular grid. But when i try to save the grid it is not a .grd file but a _net.nc file, is the only one i can export. For the bathymetry, on the quickin section, i need a .grd file. How can i do?
Thanks!

Hi Francesco,

Yes, NetCDF is the only format for unstructured grid files.

The structured Delft3D version (Delft3D 4) is fully open source. The UNstructured Delft3D version is only open source for a limited group of partners in development. Please contact sales@deltaressystems.nl in case you want to join. See this site for more information.

Regards,

Adri
