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.

Wind Input for SWAN

Youngling Posts: 3 Join Date: 2/10/17 Recent Posts
Hello All,

I am posting about generating a file for wind data in SWAN. For this question, I'm concerned about winds that are not varying in time, just supplying winds in a grid format to my domain. From my understanding with reading the manual, the winds can be given as a single grid file with U grid given first and then V grid given second in the file. Is this correct? I see that winds can also be given as separate U and V grids. Is one method superior? Or is it user preference? I guess my question is am I understanding the way to supply grids correctly in that they need to be supplied in a similar format to a .bot file, both syntax and file format? Also are there any resources or code examples online in python or matlab that I could compare to what I have for generating the wind file? Any help in this area would be greatly appreciated!

Cheers,
Nate
