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.

Problem with running the DD

Hi,

Im doing my study on hydrodynamic at Kudat, Sabah, Malaysia. I have a problem in running my DD, and I end up stuck without any solution. Everytimes i try this will appear.


Part I - Initialisation Time Dep. Data module...
runid : Kudat_delftdashboard_40m
Part II - Creating intermediate files...
Part III - Initialisation of the Execution module...
Part IV - Reading complete MD-file...
Part V - Initialisation & checking input...
Part VI - Initialisation & checking second part...

The Error messages thrown up by DD are generally not related to the error which caused them, so ignore them. Try running each of your models separately, see if they are ok, or if they give erros which you can then address.
