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.

Potential Causes - Process, Structure and Organizational Context
  • What do you think are the causes of the problems? What have you seen or heard that leads you to believe these are the causes?
  • How does the group solve problems and make decisions? Communicate and manage conflict? Coordinate its work with others in the organization? Do any of these seem related to the issues you described? If so, how?
  • Does the team have clear goals?
  • Are members motivated by their tasks?
  • Does the team have the right kind of members to do its work?
  • Do members understand and agree on their roles?
  • Do they have enough time to do their job?
  • What types of behaviors do members expect of each other?
  • What are the core values and beliefs that members share about work? Do any of these seem related to the problems you described? If so, how?
  • In what ways does the organization help or hinder the team? Is there a clear mission and a shared vision? Is the culture supportive?
  • How are team members rewarded? Does the team get enough information to do its work? Enough training and other resources? Appropriate physical space to work? Do any of these seem related to the problems you described? If so, how?
  • What is the history of the group? How has the membership and the leadership changed?
  • How do you think other people in the group would identify the problems and their causes? Would others disagree? Product Prototyping
