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.

Intuition best Example

Intuition best ExampleLet's take an example that you read a book which has more than 150 pages. You read them completely, and how much you actually remember? It's impossible that anyone remembers all the 150 pages, word by word. Does that mean you do not have the essence of the book or what it has to offer? You do have all the information you read but the information which you can readily access is very less. The information which made sense to you stays in the subconscious for faster access and rest of the information goes to the unconscious where information retrieval is hard but it is there.(Note: There are theories out there calling out the non-existence of Subconscious, where Sigmund Freud call it as Preconscious. Let's not get there as it needs deeper understanding.)Let's take the example of getting an intuition about rain while it looks sunny outside. You never know whether it will rain or not. You have a choice. Either you can take an umbrella/jacket and proceed or choose to ignore and leave. But, what if you took the umbrella and it rains? Do you have a theory that can prove your intuition? It's all about the empirical data which your brain holds. Observation of similar weather pattern at this time of the year (or) information received in a weather announcement which you weren't paying attention to etc. You can validate your intuition but you cannot understand how it is predicted.Like how data analytics works, your brain works the same way. It takes a while to figure out perfect predictions based on the huge data available in your brain. One has to validate their intuitions every time to make it perfect and correct. You could have noticed certain people whose intuitions are always correct in the workplace or in your friend's circle or in your relations. They frequently validate their intuition to make it right. I myself know of people whose intuitions are to the point. Coaching agile transitions
