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.

Flexible contracts are also known as Minimal Viable ContractsContracts are required to have better collaboration between customers and suppliers. On traditional contracts, the focus is on activities carried out by supplier and delivery of features but the focus should be on the real value which should bring more business.If your contract impedes your collaboration, contracts should be changed. Flexible contracts really help in solving the traditional approach where the focus is on the outcome and business objective is the key.In traditional contracts, there are long discussions which go quiet back and forth with a lengthy process and adds Cost of delay. Flexible contracts really help in solving the traditional approach by delivering value quickly.They are also known as Minimal Viable Contracts which has very less information in-built but different modules can be added to current conditions of the product/project/services.  A flexible contract blends TnM (time and material) with the outcome delivered. It really helps supplier to reach an outcome as quickly as possible and also ensures customer on their business needs. Coaching agile transitions
