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.

History of ScrumHistoryThe word "Scrum" is derived from the game, Rugby. In Rugby, Scrum is a method that involves the players sticking very closely together with their heads down to get the possession of the ball.The concept of Scrum is a cross-functional team working together to pass the ball back and forth and reach a distance to win.In the year 1986, Hirotaka Takeuchi and Ikujiro Nonaka introduced the word Scrum in context to Product Development in the article "The New New Product Development Game" appeared in Harward Business Review.They described a new approach to traditional product development based on their case studies that enhances speed and flexibility.In the early 1990s, Ken Schwaber and Jeff Sutherland worked together to integrate their ideas into a single framework and named it Scrum. In 1995, Jeff and Ken presented a paper describing the Scrum framework at the OOPSLA '95 (Object-oriented Programming, Systems, Languages, and Application) conference in Austin, Texas.After that, Ken Schwaber and Jeff Sutherland refined the framework further with their combined experience. That framework developed to became what we know now as Scrum. Devops Online Training
