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.

Modelling storm surge

Hi Everybody,
I am pretty new in Delft3D . I am trying to model a nested hydrodynamic and sediment transport model coupled with wave. I would like my model to include storm surge. I have a couple of questions:
1. Other than space time varying wind data, do I need to add pressure as well in order to capture storm surge accurately?2. I have a large computational domain and I could just find some atmospheric pressure data which will be located in downstream of my model (coarse grid) however I don't have any pressure data in the estuary where I have a finer grid and local effect. Is there any resource I can find the atmospheric pressures?
3. If I want to use space varying wind on the computational domain, how can I input multiple meteo stations into to the model. Can I use multiple .wnd files or I need to interpolate all of them into one file?
Thank you in advance!
Cheers,Nora

Thank you so much for this. I was into this issue and tired to   tinker around to check if its possible but couldnt get it done. Now that i have seen the way you did it, thanks guys
