intro story DELWAQ
DELWAQDELWAQ 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.

swan diag warning - length of segment short
Youngling Posts: 5 Join Date: 11/8/16 Recent PostsI'm getting a warning from a coupled wave-flow simulation in the swn-diag file for one of my four boundaries. The warning says:
"** Warning : Length of segment short, boundary values ignored".
I'm running condspecatdist using 2D spectra files as input at each location specified by condspecatdist. As you can see from an extract of the swn-diag file below, I'm not getting the warning at any of the other three boundaries. Oddly, the results seem to be ok, and I can see waves propagating in from all segments of all boundaries, so it would seem that it is not ignoring the boundary values, as the warning below indicates. But the warning is worrying, as I'm not sure why it is there, or what effect it is having in the model. Does anyone have any experience with this issue?
It looks like this:
