intro story 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.

Running Delft3D-Flow with GUI and Compiling Source code

Running Delft3D-Flow with GUI and Compiling Source code

Youngling Posts: 1 Join Date: 2/11/20 Recent Posts

I want to use Delft3d GUI, for which I had downloaded the Delft3d GUI and also downloaded the source code of Delft3D (tag number 56936).
I compiled the source code using visual studio, and then as a test, I run an example provided in source code using the script. The example was also executed with 0 errors, which means my binary is created correctly as mentioned in the Delft3d website.  

Now when, I open my .mdf file to solve in Delft3d-Flow it appears with an error message "d_hydro.exe" don't exist.

Can you please help in this regard?

Thanks, regards,
Imran Ali
