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.

Some of the way of Retrospective TechniquesDot VotingWhen teams passionately discuss the ideas, a lot emerge. There will be tens and hundreds of thoughts coming up. We cannot consider them all to be implemented immediately in the upcoming Sprint. So, we need to choose.
  • Have the team put their ideas on the board; alternatively, they can use stickies as well.
  • Have them put everything on the wall or the board. Instruct the team to grab markers and place a dot on the idea, which they think as a priority.
  • Ask the team to discuss what made them consider the top priority ones. Use inquiry and have conversations to understand their perspectives.
  • Identify ownership for the prioritized items and a target end date for implementing them. Devops Online Training
