WQ Components

Each of the components (substances) to be included in the Advection-Dispersion computations (and possibly in MIKE ECO Lab models too) must be specified in the 'WQ Components' editor. The naming of component is absolutely flexible, and no "reserved" or "standard" component names are prescribed.

The specified WQ components can be declared as 'Pollutant', 'Microorganisms', 'Temperature', 'pH', 'Salinity', 'Water Age', 'Water Blend', 'Other' or 'Fixed matter'. This categorization is used for handling of units: each component type has its own list of possible units.

When working with a water quality model using MIKE ECO Lab, each MIKE ECO Lab state variable is associated to a WQ component from this 'WQ component' editor, and the biological processes are controlled by properties defined in the MIKE ECO Lab templates. The 'Fixed matter' type of WQ component is a special type which is relevant for this MIKE ECO Lab models, and is used to describe e.g. components deposited at the bottom and not moving with water.

Decay of the WQ components is defined in the '2D decay' editor, and therefore the 'Decay' parameter in the 'WQ components' editor is ignored for 2D overland modelling.

Initial conditions for the WQ components can be specified in the '2D AD Initial Conditions' editor. Boundary conditions for the WQ components can be specified in the '2D WQ boundaries' editor. Refer to the corresponding chapters for more description.

Info

For coupled 1D-2D models, the defined water quality components are common to both 1D and 2D models. See also WQ components for 1D model.
