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.

What is the difference between Agile and Scrum and why people get confused?Scrummaster is a framework where people can solve complex problems and deliver products of high values. Scrum has 3 pillars where it stands tall and those are being transparent, constantly inspect & adapt at frequent intervals and there by failing faster.Agile is a philosophy because it is in everyone’s way of life. Agility is part of everyone’s life and Scrum is one the ways to achieve agility. If you ask me what Agility is, I would say “Common Sense”.Doing what is necessary or addressing the need of the hour matters the most than following a framework.How do you measure team performance?There is not a magic variable where you can just get a value for it and measure a team’s effort or performance. A team’s performance is directly proportional to Organization’s outcome.How you can measure it is based on how they achieve their team goal. Their participation in events, their results based on Sprint commitment, their accountability for the actions and so on. Devops Online Training
