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.

Help with CONSBL process

Padawan Posts: 70 Join Date: 3/30/11 Recent Posts
Hi All,

In my substance file I have the following substances:
Algae (non-diatoms)
NO3
NH4
PO4
DetXS1
OOXS1
POX1
POX2
DOX

The model is working for primary production but I wanted to include 1 grazer class with CONSBL.
The strange thing is that the set-up for this process needs DetX as a user input and it makes it constant.
Shouldn't this be already linked to the modelled DetCS1, DetNS1 and DetPS1 in case of zoobenthos and to POC1/2, PON1/2 and POP1/2 for plagic zoo?

Regards,

João.

Hey João,

DetC and DetCS1 are two different "substances". So you have to add DetC to your substances and activate relevant processes if you want it's value to be computed.
The same holds for DetN adn DetP.

Christophe
