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.

Dashboard problem

Hi

I'm student studying delft3d-flow and dashbaord.

I found the error message using the dashboard.  It's not working to make the file of *.bca . I searched for a soultion. There was an answer that it could be a network problem. So I waited for a day and tried again. But it still doesn't work. I wanna know the reason for this error and solve it. The error message is below. Does anyone know the answer? Could you help me? plz...

: nc_varget_java (line 31)
Could not open 'http://opendap.deltares.nl/thredds/dodsC/opendap/deltares/delftdashboard/tidemodels/tpxo80/tpxo80.nc' with java backend.

Thanks,

Kim

I have the same problem at the moment, Kim. Spontaneous server error that arose a couple days ago. I guess that the server for the tidal database is having problems. 

Hope this resolves quickly, Christian

Hi, Christian

I'm relieved to know the reason.

Thank you a lot
