Adjustment of Calibration Parameters
For the calibration of the model, the following calibration factors are provided. These calibration parameters are listed in the model in the following views:
- Kalinin-Miljukov Strand
- Processing/editing the calibration parameters of the Kalinin-Miljukov strands.
- Reservoir Strand
- Processing/editing the calibration parameters of the reservoir strands.
- Sub - Catchment
- Processing/ editing the calibration parameters of the sub-catchment.
Kalinin-Miljukov Strand
In the Kalinin-Miljukov Strand view, the calibration factors are listed: factor k and factor n.See Figure View of calibration of the Kalinin Miljukov strand)
- Factor k
- Optimization factor of the retention constant k (Kalinin-Miljukov method)
- Factor n
- Optimization factor of the retention element number n (Kalinin-Miljukov method)
Reservoir Strand
In the Reservoir strand view, a factor (double) can be entered for the Lake Evaporation (see Figure View of calibrating the reservoir strands). The correction factor is multiplied by the Lake Evaporation value with the associated time series.
Sub-Catchments
The calibration parameter of sub-catchments are divided into:
- General calibration parameters
- Correction Soil parameters
- Retention and Translation parameters
- Initial conditions
(see Figure View when calibrating the sub-catchments)
