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.

Judgement of NYC

Judgement of NYCWe have been habituated from infancy to look at the world through the lens of Judgement to meet our needs. The Judgement come in all forms like
  • We do certain things that make us good
  • If we do certain things that make us evil.
  • If we do it this way it is right
  • If we do the other way it is wrong
  • We do things because we should
  • We should not do things this way since it’s not accepted etc..
These Perspectives that we carry on with us from our young age keeps us occluded from the new learnings, accept the emerging organizational behavior changes and stops us from collaboration.
What NVC teaches us is to translate our Judgement thoughts to our needs thoughts which is a solution-oriented communication. It encourages us to share the views openly and frankly and hear/understand others view clearly. <!--td {border: 1px solid #ccc;}br {mso-data-placement:same-cell;}-->Devops Online Training
