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.

Open Processes Liberary for Linux

Hi dear D3D-Delwaq community,

I read the manual of Open Processes Liberary, on page 30, the instructions for generation of a new library for Windows and Linux are explained. However, the term "relevant source files/source files" is a general word, which does not clear which part of source code does it mean. 

I provided for my Linux D3D required files as were recommende in manual, you can see them in the attached photo.

But to generate the new poc_def.dat and proc_def.def, a GUI tools for Windows was introduced and nothing about Linux was said in Manual !Could anyone tell me how in Linux can I generate these two files (proc_def.def and proc_def.dat)? I know that in Linux should a Makefile using make command run, which is like build in visual studio but am I right? Is there a Makefile for producing proc_def.def and proc_def.dat in src?
