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.

When i start a calculation in Flow, the massage "Executable d_hydro.exe not found on directory C:/Program Files/Deltares/Delft3D 4.02.02/win64/flow2d3d/bin" appears. What is wrong?

Hi Denis,

After downloading and installing the GraphicalUserInterface, you still have to compile the kernels yourself. Please follow the instructions on this page.

If you don't want to compile the kernels yourself, you can buy a service package.

How does one go about compiling the kernels , can you give me a walk through please ?

Hello Adri,

 

I am having the same error message as the people above. I found that I do have the d_hydro.exe but it is not in the c: drive (this is because I am using an university computer and need permission to access the c: drive).

Will the computations work if I simply move the folder from the current E: drive to the C: drive? Please advise!

 

Thank you,

 

Gabriel
