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.

Dear all,

I was facing some issues with the new GUI and DELWAQ which I would like to share.

PLCT windows freeze when I try to re-open a recently saved processes file (*.0) .
I could reproduce this bug in a windows 10 and windows 7 (VM).
Solution: Downgrade the GUI

When I tried to import a segment file using the GUI, it complains that I should select the file, even when the file is already selected.
Solution: Downgrade the GUI

DDcouple using D3D-flow parallel run output (multiple com files).

The unique com file didn't worked.
The solution was to use the ddcouple within the following post:

Thanks for mentioning this. We must have a look at these issues!
