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.

Why do we need Scrum?
  • Scrum helps product teams maximize ROI for products in complex domains by reducing the Cost of Delay and Cost of Production through safe to fail experiments called Sprints.
  • Scrum makes clear the relative efficacy of your product management and work techniques so that you can continuously improve the product, the team, and the working environment.
Scrum is a framework, which can be useful in complex domains. Scrumis just enough to have some order in place and give you space to be creative in solving the problems. It advocates a time boxing approach called Sprints. Sprints are nothing but safe to fail experiments to uncover the problem to figure out the next steps.It's safe to fail because the amount money you would lose if the experiment fails is much lower compared to failing the whole product. It’s an experiment because there is always learning.Scrum encourages teams to review the system and improve it to increase the effectiveness of the team.Scrum enables product development teams to get frequent feedback from customers at the end of every Sprint. Devops Online Training
