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.

If we demo in between sprint, won’t Product Owner change his mind again?

If we demo in between sprint, won’t Product Owner change his mind again?People usually forget the fact that Sprint Review is not for Product Owner but for the Stakeholders to review the work done by the Development team. Product Owner will get the demo of the product backlog items once it is done by the development team.Product Owner of course will provide the feedback immediately and any changes pertaining to the feedback will be done soon. Product Owner after seeing the product backlog item in the form of a usable feature, he/she can change his mind.It is possible that PO assumed something and is not satisfied with what is built. Also, possible that PO can change his mind on his assumption were wrong with how the product is built.Product Owner knows the pulse of the customer and the market and decides/changes based on the same. Moreover, team should validate their assumptions faster by demoing it to the product owner as fast as they can. Devops Online Training
