SOBEK 1DWAQ (Water Quality)

This module is based on the water quality 1D/2D/3D simulation engine which offers you more than 30 years of collective water quality modelling experience world-wide. It models almost any water quality variable and its related water quality processes. This component is highly flexible due to the many standard options and user-defined options available. It uses a library of 900 processes and substances, including eutrophication, adsorption, desorption, nutrients, bacteria, oxygen, phyloplankton, heavy metals and micro-pollutants. The interactive processes editor allows you to select the water quality variables and processes you want to model. Pre-defined sets of water quality variables and processes can be used for particular problems or following the standard set of rules and regulations for specific regions. To analyse the origin of pollutants in any water system, fraction computations can be easily made. No additional input data is required for fraction computations, which makes it easy to trace water or pollutants from to its source throughout the network. The state-of-the-art numerical schemes of the water quality 1D/2D/3D simulation engine use a finite volume approach and the module display mass balances. It is fully integrated with the standard user interface. Which means that standard network editing, animations, graphs and other post-processing facilities of SOBEK are used. Various options are available to avoid the tedious job of defining your boundary conditions. For example defining default boundary values for clusters of inflow locations. The possibility to overwrite these defaults for specific locations, and the option to link your own ASCII input file with boundary data.

Note that the D-Water Quality module will be the successor of the SOBEK 1DWAQ module in the new Delft3D Flexible Mesh Suite.
For researchers and software developers, the source code of DELWAQ, the computational engine of D-Water Quality, is already available in open source.
