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.

Results generation and calibration

hello,
My QUICKPLOT is not working and I would like to know if there are any other tool/method for me to obtain my results.
Thank you!

There are a number of Delft3D Matlab tools available which can help you interrogate the output files easily.
I think the link below is the link to the delft3d_matlab tools in the open earth tools repository.

https://svn.oss.deltares.nl/repos/openearthtools/websites/trunk/matlab/applications/delft3d_matlab/

For example, to extract the water level results from observation points in my FLOW domain (from the *.trih file) I use:


fid=qpfopen(strcat(trih_path,'\trih-*.dat'));

trih=qpread(fid);

Stations = qpread(fid, trih(3), 'stations');

N=length(Stations);
for k=1:N
model.(sprintf('%s',Stations{k})) = qpread(fid, trih(3), 'data', 0, k);
end


This outputs a matlab structure with all of the stations containing water levels and times. You can change the index after trih(N) to change the variable you wish to output.

Hope this helps,
Erin
