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.

Interaction D-Waq and D-Part

Hi,


wanted to know if it is possible to interact a bloom of microorganisms in the D-WAQ with an oil spill on the Paticle Track.

 

Thanks.

It might be possible, but you will have to do some coding.

 

In the Delwaq Input file manual in chapter 2.3.1, you can see how to hook up Particle tracking in Delwaq. You will than have the concentrations of the oil spill available in Delwaq. There, you can add an extra processes that reduce available based on that oil concentration. How you could do that is described in the Open PLCT manual.

Hello, Michelle, after using parallel computing flow module, I chose to calculate the core n = 24, because my computer is 24 cores. As a result, com files and hyd files are divided into 24 copies. Then I downloaded ddcouple and ran DDB files. As a result, only hyd files are merged, and the total size of the merged hyd files is 2.5 kb. My question is, why are files split after parallel computing? And why is the merged hyd file so small? Thank you for your advice.

Apabila saluran air telah terpasang, maka proses terakhir adalah pengurugan kembali galian disamping kanan kiri saluran agar saluran tidak bergeser. Hati-hati dalam pelaksanaan proses ini karena saluran dapat bergeser ketika terdorong oleh gaya dari benda urugan dan pemadatan. Setelah saluran terpasang sebaiknya memasang caping beam dari beton agar saluran tidak bergerak ke kanan dan ke kiri ketika terjadi proses pengurugan kembali. Setelah proses pemadatan harga u ditch 2020, area kerja harus dibersihkan dari bekas tanah galian, material lain serta peralatan
