The Percent Removal filter removes a fixed percentage of the constituent associated with the quick flow of the functional unit (FU) and a fixed percentage of the constituent associated with the baseflow.
Scale
This model is a catchment scale model.
Principal developer
Cooperative Research Centre for Catchment Hydrology
Version
Source v2.10
Dependencies
Requires a constituent generation model to be assigned to the corresponding functional unit(s).
Availability/conditions
The Percent Removal filter is automatically installed with Source.
Flow phase
Each time-step, the model removes a fraction of the constituent load that was generated from the functional unit.
The constituent generation models generate both a ‘quick load’, associated with the quick flow component of runoff, and a ‘slow load’, associated with the slow flow, or baseflow, runoff component.
The quick load is reduced by the Percent Removal filter using the PercentRemovalQ parameter.
Equation 1 |
|---|
The same process is applied to the constituent load associated with the baseflow (the ‘Slow Load’ here), using a separate, PercentRemovalS parameter.
| Equation 2 |
|---|
The result of the filter is the total load for the functional unit, which is the sum of the filtered quick load and the filtered slow load.
| Equation 3 |
|---|
Input data
This model operates on the incoming constituent load, which is automatically provided to the model by Source.
