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.

Subconscious mind is responsible for the habits

Subconscious mind is responsible for the habitsIf subconscious mind is responsible for the habits I have, how will I change a habit? If you are planning to start a tremendous change suddenly and drastically, then it might be difficult to implement. If you succeed in implementing it, you will not be able to sustain the change. That’s because your routine is different and your conscious is struggling to make sense of it. How to do it then? Start small. One good thing I have learned over the period is to switch to trivial things whenever you are going to perform something from your routine. I know its still confusing and so I will explain with an example.First, identify one habit which you want to change. Put that to test and see if its nagging you, driving you, not letting you sleep etc. for changing that. It should drive you to get rid of it and you should be self-motivated. Else, you will be wasting time doing something which is not needed for you. Let’s take an example where you want to quit smoking. Instead of smoking, when you have the urge, what do you want to do?Let’s say you want to walk till the pantry, fetch a bottle of water, walk and little around the cabin and come back to your seat. Start the small activity instead of the regular habit. You may ask, what will I do in home. Choose what do you want to do when you have the same urge in home and continue doing that. Slowly make that as a routine and your subconscious makes a note of it. Piece of cake, isn’t it? Coaching agile transitions
