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.

I try to run a flow-wave coupled model using a space varying wind and pressure defined on computational grid, but I got an error as follows:

*** End of morphological input

*** MESSAGE Wind and pressure specified on the hydrodynamic grid
*** ERROR Meteo input: wrong entry in meteofile tst.wnd; expecting keyword or commentary, but found: -1.020229 -1.011463 -1.011463 -1.001666
*** ERROR Flow exited abnormally

The numbers "-1.020229 -1.011463 -1.011463 -1.001666" are located in the block of "TIME = 12.0 hours since 2015-09-30 00:00:00 +00:00", not in the beginning (see the Fig attached).

What's going wrong?
