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.

Delwaq problem by generating proc_def.def and proc_def.dat

Dear Delwaq developers,

I am trying to follow the instructions on page 30 of the Open Processes Liberary (OPL) manual. I did it for both Linux as well as Windows, but none of them produced the proc_def.def and proc_def.dat after compiling (the compiled results are attached). I think this was not mentioned in manual or Delwaq has a problem by producing the proc_def files. Could anyone tell me what should I do after build/compiling ?

The definition of the processes you add via the Open PLCT GUI to the set is automatically stored in the processes library files you selected. If you open those, then you should be able to see the new processes. Note that this may be the processes library files that come with the installation.

By the way: I have added the makefiles needed to make the waqpb programs on Linux - these were missing (we simply never created them for these tools). After an update of the source code you should be able to build them as part of the general build process.
