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.

Problem in creating bathymetry file

Hi everyone, I am currently trying to model a strait located in Indonesia, and have used delft dashboard before. It seems to be working just fine a few months ago till  today. Its seems not to be able to create bathymetry data and it keeps on appearing:Error using snc_read_backendCould not determine which backend to use with C:\UsersError in nc_vargetrError in nc_vargetError in ddb_getShorelineError in ddb_updateShorelineError in ddb_uodateDataInScreenError in ddb_zoomInOutPan>StopPanError while evaluating figure WindowButtonUpFcnHow can i get this problem done? Any insights would be appreciatedThank You, Feldy
