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.

Micropollutant modelling


I am planning to study micropollutant (PPCPs) modelling that are residue in the river water . I would like to ask whether this substance can be found in DELWAQ?

Anybody can help me?

Thank you in advance =)

Hi Zulhafizal,

The list of available organic micro polutants can be found in section 9.1 of the Technical Reference Manual.
In this list you will find a substance with id OMP, which is a generic omp which you can configure to have the desired properties.

If this turns out to be unsufficient to meet your needs, extending the library is very encouraged and we'll be glad to help you with this.

Dear Christophe,

Thank you for your prompt reply.. Really appreciate it.. I'll look into that manual..

Thanks once again..
