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.

Initial Conditions - Bloom - Error code 6

Youngling Posts: 5 Join Date: 1/23/12 Recent Posts
Hi,I'm trying to set a simulation in a vertical and horizontal aggregated mesh using the .qin files from a not aggregated previous run as initial conditions. However, when I run the model it crashes delivering the message - Error code 6.
Looking into the bloom.dbg file I found this message: "The number of species 53 exceeds the maximum 15 set by the program."
After some tests I've managed to overcome the error using the .qin files for all substances, except for the algae.  But I still need to set initial conditions for algae concentration.Any advices?Thanks in advance.Leonardo.
