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.

Using Visual Studio 17 to compile Delft3D

Using Visual Studio 17 to compile Delft3D

Hello all, I am trying to compile Delft3D using Visual Studio 2017, but I am not sure which VS 17 modules I should install. I have had to use VS 17 because I can’t find a version of Intel Fortran Compiler to download, that is compatible with VS 15. On this site’s source code instructions, it says:

Be sure that the following modules are installed in your VisualStudio (by default, they are not installed):
  • - "Common Tools for Visual C++ 2015"
    - "Microsoft Foundation Classes for C++"
    - "Windows 10 SDK"
    - "Windows 8.1 SDK and UCRT SDK"
    - "Visual C++ MFC for x86 and x64"
    - "C++/CLI support"
    - "C++ Universal Windows Platform tools"
    - "Common tools for Intel compiler projects"
    - "Intel(R) Software Manager"
    - "Intel(R) Fortran Expression Evaluator"
    - "Fortran IDE"
However, not all of these appear as options on VS 2017. I was wondering if anyone knew of the equivalent packages I should install, so that I can compile Delft3D without errors.
Alternatively if anyone knows how I could get ahold of a Intel Fortran 16 installer that would be great.

Hi Chris,

I used Microsoft VS 2015 and Intel Parallel Studio 2018. Intell Parallel Studio needs a license but I was able to get a free license (for 1 year) since I am a student. So far, these two versions worked well for me.
