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.

Wave - Rock out crops

Padawan Posts: 35 Join Date: 7/31/12 Recent Posts
Hello All,


I would like to know if any one has attempted breaking and reflection near rock outcrops in wave model.

I'm aware of alternatives of non erosive bed in flow and couple with wave (but leads to large velocities and excessive erosion at the rock foot in the flow)

Every advice is welcome.

hank you so much for this. I was into this is https://vidmate.onl/download/ sue 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
