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 duration of the Sprint Retrospective?

What is the duration of the Sprint Retrospective?Sprint Retrospective is three hours time-boxed event for a one-month Sprint. It will be 45 minutes for a one-week Sprint, 1.5 hours for a two weeks Sprint and 2.15 hours for a three weeks Sprint. It will be shorter for shorter Sprints.
Scrum stands tall on three main pillars and they are Inspect, Adapt and Transparency. Every event in Scrum is an opportunity to inspect and adapt. Frequently inspect and adapt helps the Scrum Team to create an empirical process. Scrum also says that too much of inspect and adapt should not get in the way of creating a “done” product increment. Sprint Retrospective is a formal opportunity for the Scrum Team to inspect everything that happened in the Sprint and create a plan to improve and implement during the sprint.Learning and improvement is continuous. Scrum believes in continuous learning and continuous improvement. There is no ultimate state that one has reached, there is always further and beyond. If a Scrum Team thinks that they have reached a state where they do not have to improve anymore, then their stagnancy starts there. Stagnancy leads to a state of worsening. Teams should always find ways and means to improve themselves, their ways of working, processes, tools and basically everything.  <!--td {border: 1px solid #ccc;}br {mso-data-placement:same-cell;}-->Devops Online Training
