Downscaling models for hydrology:
The downscaling of hydrological information is based on the HYPE hydrological model. For Stockholm the model is based on the Swedish model S-HYPE, for Bologna and Amsterdam the model is based on E-HYPE.
For details about the setup please see:
- The model setups for each city are described in D3.3
- Calibration and simulation runs is described in Section 2.1 of the hydrological validation report (D5.3)
Essential Climate variables (ECVs) from HYPE:
| ECV | Unit | Hype output variable |
| Local runoff | mm/h | crun |
| Surface runoff | mm/h | cros |
| Evapotranspiration | mm/h | evap |
| River discharge | m3/s | cout |
| Soil moisture | mm | smfp |
| Snow water equivalent | mm | snow |
