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.

Who is a Business Analyst?A Business Analyst is a person with appropriate skills to perform Business Analysis. Business Analysts are responsible for: • understanding enterprise problems and goals, • analyzing needs and solutions, • devising strategies, • driving solution development, and • facilitating stakeholder engagement and collaboration.Change is defined as the act of transformation in response to a need. Need is a problem or opportunity to be addressed. A solution is a specific way of satisfying one or more needs in a context. Value is the worth, importance, or usefulness of something to a stakeholder within a context.In simple words, Business Analysis is creatively solving user’s problems through solutions that generate value for all stakeholders (users as well as the organization building the solution). Business Analysis the process of uncovering the current state from different perspectives( customers, users, and organization) and determine activities required to evolve towards the future state.A Business Analyst should have the following skills to be an effective one: • Creative Thinking, • Decision Making, • Problem Solving, • Systems Thinking, • Business Acumen, and • Facilitation Devops Online Training
