This renewed effort in calibrating the two largest operational hydrologic models for the Netherlands is intended to address:
- Primarily timing lead and lag times in event onset and arrival on a per catchment basis.
- Improving high and low flow simulation accuracy.
- Providing uncertainty estimates that stem from calibration.
- Reproducibility.
A workflow is built for the Meuse, which is then deployed for the Rhine.
This workflow is borrowing and expanding on the work done for:
- Interreg (calibration, Laurene Bouaziz and Anais Cousanon)
- Puget (Joost Buitink and Brendan Dalmijn)
The innovations and contributions of this new effort in model calibration are:
- Event timing metrics as calibration objectives (mean timing offset and std of lead/lag)
- Cascading calibration (dependency tree solver)
