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.

Problems when importing the discharge file

I always get into trouble when import the discharge file in Delft3D. Generally, I define the location of the discharge and save the .src file and .dis file first, then I open the .dis file with a text editor, usually Notepad++, and copy the data from Excel and replace the discharge respectively. Sometimes it works well, but sometimes not. And if I revise the data in the file and reload it. It always get into trouble.
Error info: "No time-series found for discharge Dis1."
I can make it work if I redo it by save a .dis file and replace the data one by one again. But if I have several discharges, it will be a hard work.
I don't know how to upload the file, so I get a picture for the beginning part of the file.
