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.

Use the binary files created with the other computer on my laptop

Hello all, 

I was trying to download the source code and compile it but faced lots of problems with the VS and ifort compilers. Finally, I quit and just was very upset not to get the binary files. I am using VS2012 and IFORT13. I tried to follow all the steps correctly but I did not succeed. The build process continue until I got a fatal error and it says "/Release/data.lib" can not be opened and then the program crashed and even I cannot close the VS and I have to restart the computer. 

I am wondering if it is possible that someone compile the last tag version successfully can upload the binaries file here, so I can use them on my laptop for my modeling purpose.
