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.

dear delft3d master user..

Is there a way to input wave data (e.g. radiation stresses) that
have already been calculated by a wave model other than
SWAN into the Delft3D hydrodynamic model?
We have an existing wave model for an area and we want to couple it to a hydrodynamic/sediment transport model.

forum user said,
make communication file(com-*.dat) yourself.
But, it was used for delft3d openearth tool.
Then, what is the convert file in openearth tool?

In definite example..
we have 1 month swan result.
we want to convert this data to delft3d input file for calcuate sediment modelling.

this data follow:

For general user, how to convert delft3d com-*.dat for this file?

If i made com-swan.dat, forum master?(concerned person) said that user used this script for delft3d wave-currnet interaction.


I try to download this adress, and findout this script. But, i don`t know how to use this program.

Have you process or example for user??

openearthtool package download ok.

In detail, program run and make input example are not suggest openearthtool..

please answer me.
