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.

Implicit expectations

Implicit expectationsImplicit expectations: These are the expectations that the stakeholders have on the leaders. The leaders rarely do understand the impact of these expectations and the effect that it has on their overall effectiveness. Some of them are commitment, engagement, listening, fair treatment, competence, being an inspiration, and so on. One may wonder, why would someone become a leader keeping in mind these expectations. Coming to leadership, it is a responsibility. The responsibility is not straight forward and or affected by the increase in change, complexity, and connectivity. Life is in a complex domain and one cannot predict what may come. Leadership lies in accepting what had happened and working towards making it right. Take an example of the COVID situation, every nation’s leaders are expected to make decisions and things which are right for their people. Both implicit and explicit expectations are there and they will be unrealistic considering the situation at hand.Despite all of the challenges they face, great leaders do love their jobs as leaders. Some may even call that as a calling. Many great leaders see them as challenges than hurdles or blockers. They do operate with more transparency and disclosure as they endure greater scrutiny. The leaders use these chances to influence people, create positive results, and change things. As we have discussed earlier in the article, it’s a responsibility and great leaders do handle these expectations with ease. Devops Online Training
