MIKE ECO Lab Constants

Constants are values which are fixed in time and affect some of the processes on the state variables. They are automatically listed in this editor when the MIKE ECO Lab template is imported, from the 'MIKE ECO Lab templates' editor.

This editor is used for setting the values of the constants used in the MIKE ECO Lab model, typically during model calibration:

  • ID: Unique MIKE ECO Lab constant identifier in MIKE+.
  • MIKE ECO Lab template: MIKE+ ID for the template to which the constant belongs.
  • Constant ID: Constant identifier in MIKE ECO Lab template.
  • Default / uniform value: Value for the constant, when it’s defined as uniform
  • File name: Path and file name for the 2D data file containing the constant values, when the constant is defined as varying in domain (only available when the MIKE ECO Lab template is connected to the 2D overland model).
  • Item: Data item selected in the file.
  • Local values: From the 'Local values' tab, it is possible to apply local values on the 1D network, which will override the default value. For MIKE ECO Lab templates connected to the 2D overland model, use the option 'Varying in domain' instead. Multiple local values can be defined for the same constant, with the following settings:
    • Interpolate this constant between local values: If this option is selected, local values for the same constant will be interpolated in space when they are defined on the same river or pipe. If not selected, values will be interpreted as local values valid only for the specified chainage.
    • Location: each local value is specified either for a specific node or storage (respectively from the CS network and the river network), an entire link (river or pipe), a point on a link (at a single chainage), a reach on a link (defined from a start chainage to an end chainage), or finally using a list. When using a list, the local value is applied to all nodes, storages, rivers and pipes in this list.
    • Local value: local value for the constant.
  • Description: Free text description for the constant defined in the Description tab page of the editor.
