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.

Delft-3D Flow, Linux, Ubuntu | how to completely UNinstall

Hello world!

I wish to fully uninstall my current Delft3D suite and repeat the process from scratch.

My distro is Ubuntu Precise Pangolin. The info in the Installation Manual briefly refers to a Red Hat distribution only ('rpm -e Delft3D')
  • I was thinking of a 'sudo apt-get purge <path>/d_hydro.exe'. Is there a(nother) way to do this that you would recommend?
  • Could you also mention if the proposed solution would also be applicable to D-Flow FM as the need arises? (Two pigeons with one stone...)

Thanks a lot in advance for dealing with this.

Sorted! For future reference and corrections/integrations at any time, I did the following

  • Go the directory containing the configuration files (<path>/src/)
  • Run
    make uninstall
  • Run
    make clean

According to The GNU Make Manual the aim of item 2 is
to delete all installed files -- the copies that 'install' and 'install-*' targets create.

The aim of item 3 is
to delete all the files that are normally created by running 'make'.

Therefore I chose to run both actions by undoing the sequence 'make' and 'make install' in reverse order upon using 'sudo' rights. The directories /usr/local/bin were effectively cleared of the Delft3D executables. I missed out checking the content of /usr/local/lib before taking action, but I assume it worked equally well.

As far as I can see, this procedure is independent of the Linux distribution, so it seems to be more general that the one currently suggested in the Delft3D - Installation Manual v1.0, which is specific to the Red Hat distro (Section 4.6).
Subject to the developers' sanity and laugh checks, a distro-independent procedure like this might possibly be included in the manual.
