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.

Trouble importing observation points to Delwaq
observation points .obs import

Hi,

I have been unsuccessful in importing observation points to Delwaq. Attached is my observation point file (.obs). When I try to import the points they all plot in the same, incorrect, random location. Has anyone else had this problem? The observation file format seems pretty straightforward, am I missing something?

Thanks,
James

I cannot see anything wrong with the file itself. The one thing I can imagine is that the coordinate system in the (hydrodynamic) grid doesn't match the coordinate system in the observations file. Could you check that?
