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.

Kanban is design of both physical and software products

Kanban is design of both physical and software productsKanban is a method for defining, managing, and improving services that deliver knowledge work, and the design of both physical and software products. The Kanban Method is based on making visible what is otherwise intangible knowledge work, to ensure that the service works on the right amount of work—work that is requested and needed by the customer and that the service has the capability to deliver. Kanban focuses on the delivery of services by an organization—one or more people collaborating to produce working products.As per the super market concept, limiting the stock and making it available at the same time is exactly the concept behind limiting the amount of work in progress.Kanban is a popular Agile framework used by software development and support teams. Kanban originated almost three forth of a century, back in time. During late 1940s, Toyota wanted to optimize its engineering processes. The inventory management system which super markets use, was very efficient because they efficiently decrease the amount of excess stock from the consumer’s consumption patterns. This approach helps super markets to keep stock of any given product which the customers need and avoid excessive stocks.The goal of Toyota is to make their inventory available to match with their consumption of the same in manufacturing. This leads to the evolution of JIT (Just-In-Time) manufacturing process. <!--td {border: 1px solid #ccc;}br {mso-data-placement:same-cell;}-->Coaching agile transitions
