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.

DELWAQ MAXIMUM GRID NUMBER(MAX CELL)?

HI, BECOME A DELWAQ USER.

IN SPITE OF READ MANUAL, MODEL SETUP & APPLICATION IS NOT EASY FOR ME. '_'..

I HAVE ANY QUESTION FOR DELWAQ MODELING.

IN CASE OF ANOTHER MODEL(EX. efdc.. etc), IT IS ALREADY DETERMINED MAX GRID_NUMBER(EX. X,Y,Z).

HOW ABOUT THIS MODEL?

X,Y,Z IS DETERMINED FOR USED DELFT3D GUI?

PLEASE TELL ME.

THANKS YOU.

Hi Hrejet,

The dimensions of your WAQ domain are initially determined by the the FLOW (hydrodynamic) simulation. With the coupling between FLOW and WAQ you can then aggregate your dimensions in the horizontal, in the vertical or in time.

If you are using the hydrodynamic results (FLOW) from somebody else you can discuss with them how to best change their domain without incurring into excessive numerical diffusion or make changes that are not reasonable in terms of hydrodynamics.

If you want to start from scratch you have to learn how to use Delft3D-FLOW first if you don't know that already.

Regards,

João.
