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.

Model 2 - Heat - Absolute flux, net solar radiation

Hello everyone.

My Delft3D FLOW GUI is the version 3.56.29165, and the second Heat flux Model 2 (Absolute flux, net solar radiation) present the necessity input the SKY CLOUDINESS.
But, in FLOW manual, page 76, is write:

Sky cloudiness --> The fractional blocking of the solar radiation by clouds in [%]. Required by heat flux models 1, 4 and 5.

The model 2 is really required the sky cloudiness in the calculation?



Thank you very much.
