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.

Product Backlog

Product BacklogThe Product Backlog is one of the primary artifacts in Scrum. Each item in the Product Backlog is called a Product Backlog Item (PBI). Each of these items could be a
  • Functional requirement
  • Non-functional requirement
  • Defect
  • Enhancement
  • Change Request
and anything that impacts the product that goes into the Product Backlog.The whole Scrum Team (Product Owner, Development Team, and the Scrum Master) collaborates to add more details to the top priority Product Backlog Items. We call this Product Backlog refinement.The purpose of this activity is to have just enough details for PBIs for the first few sprints. Refinement is an ongoing activity that should happen in every Sprint, as Scrum suggests. Devops Online Training
