intro story DELWAQ

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.

Dear all!

I am trying to create Depth file from xyz file .but my xyz file in sperical coordinate system ,my depth file and grd file should be in cartesian coordinate system.so pls someone help me to change my xyz file coordinate system. I upload my xyz file 

Thank you

Hi shuluckson sathiyaseelan,

Which local cartesian coordinate system do you want?   You may do it using Supertrans function in OpenEarth tools. 

Cheers,

Qinghua

Hi Qinghua Ya,

Thank you,

for my project i need to take Srilankan east coast (lat 6.733 to 9.651 long 80.677 to 82.602).Can I take cartesion coordinate file for this coastal area?

Hi,

as Qinghua said, you should have to use Supertrans function of OET or you can use the Dashboard (Supertrans is integrated to the GUI). Using Dashboard, you can design your grid and get the bathymetry in the coordinate system that you want to work.

 

Regards,

Hi, Shuluckson Sathiyaseelan,

Using OpenEarth SuperTrans functions, I transfered for you, assuming your original coordinate is WGS84(4326), to Kandawala / Sri Lanka Grid (EPSG 5234).  See if it works for you.

Best Regards,

Qinghua
