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.

Delwaq results as time-series per layer

Padawan Posts: 65 Join Date: 6/25/16 Recent Posts
Hi, why in a 3D-model using Delwaq, it is not possible to see time-series for each layer using d3d_qp in Matlab? however using the map-file (.ada-file) it is possible to see results layer per layer in map. Should I activate some options in Input file to see the time-series  layer per layer? or it has not been programmed for Delwaq to see time-series of results layer per layer? If it is not possible, what type of averaging has been implemented for the single time-series for all layers. Using .hda-file, I get only one time-series for all layers!

An estuary is a partially enclosed coastal body of brackish water with one or more rivers or streams flowing into it, and with a free connection to the open sea. basketball legends
