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.

Run long-term AD using a repetitive HD pattern

Hi all,

I would like to ask about the possibility of running a long AD model but using a repetitive HD pattern (e.g.:spring/neap cycle that repeats)
The idea behind this is that as you know the HD takes long time to simulate, while running an AD model (having the HD) is fairly quick.
This would be used to assess the cumulative fate of conservative substances over a long period of time.
I understand I am making some assumptions by doing this but that is ok at the moment.

I believe this was possible in the older versions but not sure if it can be done with the new Flexible Mesh version.

Any comments/guidance?

Thanks in advance,

Fernando.

Hi all,

just found in this manual

https://content.oss.deltares.nl/delft3d/manuals/D-Water_Quality_User_Manual.pdf (page 77/396)

a brief description and as it is explained, it should be eru straight forward.
I will try and have a look, anyway let me know if you have some tips
