The Observed Concentration model is used to set quick flow and slow flow concentrations.
The observed concentration model operates at the functional unit scale at the time-step of the main model.
Applies to catchment models built in Source.
Observed Concentration is automatically installed with Source.
Time series, constant value or function for each functional unit in concentration units, such as mg/L. If using time series data, it should be gap-filled.
This model sets the constituent output of the target functional unit and, through this, the constituent output of the sub-catchment and the downstream node. You can record constituent output at the functional unit, the surrounding catchment or any point downstream.
