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.

unable to compile delwaq

I am unable to compile delwaq on windows 7 pc using visual studio 2008 and Visual Intel Fortran compiler 11.1 and I am hoping someone will help me out.

I added waq projects to existing d_hydro_open_source.sln project as shown in the webinar files. When building the project, however, almost all projects were successfully compiled except waq projects shown. I tested the recent TRUNK as well as previous tagged versions. Build configuration was set to win 32 release.

It generated numerous warnings and errors that include:

LINK : fatal error LNK1181: cannot open input file 'delwaq1_lib.lib'
LINK : fatal error LNK1181: cannot open input file 'delwaq2_lib.lib'
LINK : fatal error LNK1181: cannot open input file 'waq_io.lib'
G:\Delft3d_Trunk\src\engines_gpl\waq\packages\delwaq2_lib\src\waq_omi_lib.f90(153): error #6460: This is not a field name that is defined in the encompassing structure.
G:\Delft3d_Trunk\src\engines_gpl\waq\packages\delwaq2_lib\src\waq_omi_lib.f90(166): error #7002: Error in opening the compiled module file. Check INCLUDE paths.
G:\Delft3d_Trunk\src\engines_gpl\waq\packages\delwaq2_lib\src\waq_omi_lib.f90(427): error #6366: The shapes of the array expressions do not conform.

Thank you in advance.
