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.

Executing .bat file Delft Dashboard

Hi

I've recently started using Delft Dashboard, and was trying to follow the tutorial for setting up a tidal simulation for Sao Tome. After completing all the steps, I'm meant to execute a batch file that is created.

The problem is when I click the the .bat file a command window opens and closes before the file is executed. I have tried running the file through the command window but I keep getting this message: 'The system cannot find the path specified'.

Anyone have any idea what the problem might be?

Cheers!

Hi Augusto,

If I'm correct, the Dashboard scripts are based on Delft3D-FLOW version 5.xx. If you built the source code based on Delft3D-FLOW 6.xx the Dashboard batch script will not work.

Work around:
Copy from (your local checkout of) https://svn.oss.deltares.nl/repos/delft3d/trunk/examples/01_standard, the files "run_flow2d3d.bat" and "config_d_hydro.xml" into your working directory containing all the input files. Open the xml-file in an editor and adapt the name of the mdfFile file. Open the batch file in an editor and check that D3D_HOME points to a directory containing the binaries.

See the release notes for more details.

Regards,

Adri

I am having the same problem...anyone found a resolution to this? I'm trying to work through the saotome tutorial.

I am running delftdashboard through matlab and my version of Delft 3D is 4.00.02

My working directory for delftdashboard is C:\delftdashboard\saotome
My working directory for Delft 3D is C:\Delft3d

I did everything exactly the same as in the tutorial, but when I try to run the batch file (in the command prompt), I get this:

C:\delftdashboard\SaoTome>batch_flow
'\deltares_hydro.exe' is not recognized as an internal or external command, operable program or batch file.

I tried the work around suggested, but it did not work.

Please help!
