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.

Challenges in AdoptionMy wife is not a dog person. She has her reservations when it comes to a dog as she grew up thinking dogs spread diseases. Her mental model was so strong. After a couple of months, she started liking him very much.I am a trainer, coach, and consultant by profession. It involves traveling, and I had to be away from home for my work at times at a regular interval. My wife is a working professional, and my kid will be off to school. That leaves the poor creature all alone during the day, expecting us to be home soon.Dogs howl when they are alone, and its a cry. It's a myth that when a dog cries, something terrible happens. The neighb ors started complaining, and my wife started believing in that myth. She started complaining to me about the howls. Devops Online Training
