intro story 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.

Obtaining water levels/elevation in QUICKPLOT

Hello, I need to obtain water level/elevation output from QUICKPLOT. Is there a way to do so? I don't see it as an option in the drop down list. I've gathered that I may be able to use GPP to do so, but was hoping to obtain it through QUICKPLOT, as I am not familiar with using GPP.

Hi Audrey, using D3D Matlab-Toolbox you are able to load all of computed variables. You can find the Toolbox by OpenEarth or in trunk of Delft-Website: https://svn.oss.deltares.nl/repos/openearthtools/trunk/matlab/matlab/
