SWBM is one of the 13 global hydrology models following the ISIMIP2a protocol which form the base of simulations for the ISIMIP2a global water sector outputs; for a full technical description of the ISIMIP2a Simulation Data from Water (global) Sector, see this DOI link: http://doi.org/10.5880/PIK.2017.010

Information for the model SWBM is provided for the simulation rounds shown in the tabs below. Click on the appropriate tab to get the information for the simulation round you are interested in.

Spin-up
Was a spin-up performed?: Yes
Spin-up design: 5 years with climate data provided

Calibration
Was the model calibrated?: Yes
Which years were used for calibration?: Calibration against multiple hydrological reference data available in different years, overall spanning a period from 1984-2012
How many catchments were callibrated?: >100 near-natural catchments were used
Vegetation
Is co2 fertilisation accounted for?: No
How is vegetation represented?: not specifically accounted for
Methods
Potential evapotranspiration: net radiation used instead of potential evapotranspiration
Snow melt: Degree-day method
