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.

Good Morning,

I have already received your package for Delft3D 4.03.01 and I attempted to run a specific example : ‘The Friesian Tidal Inlet’ , which is located in the Delft3D_Flow_User_Manual.

It is worth mentioning that the data for this example are from the Delft3D 4.02.01 version. In addition, when I executed the scenario (in GUI/start window) , I received the following message: ‘The d_hydro.exe file does not exist’ . Thus, I utilized the d_hydro.exe file from a previous version (Delft3D 4.02.01 ) , but then I received a new message: ‘ the MDF and DDB files don’t exist’. Can anyone  send to us the d_hydro.exe file for Delft3D 4.03.01 version ?

Please if you can, help me with this problem!

Hi Christoforos,

when you download the GUI package from the Deltares ftp and you do not have the service package, it does not mean that Deltares gives us the Delft 3d system bin files, we have to compile the system souce files.

You should try to compile the Delft 3d and once you have get the bin files, you will copy these files in each of the folders you have in GUI installation folder.

 

Regards.
