Impact model: SWAT-VUB

SWAT is one of the 15 regional hydrology models following the ISIMIP2a protocol which form the base of simulations for the ISIMIP2a regional water sector outputs; for a full technical description of the ISIMIP2a Simulation Data from Water (regional) Sector, see this DOI link: http://doi.org/10.5880/PIK.2018.007

Resolution

Spatial aggregation: subbasins

Horizontal resolution: subbasins

Temporal resolution of input data: climate variables: Daily

Temporal resolution of input data: co2: 30 years

Temporal resolution of input data: land use/land cover: constant

Temporal resolution of input data: soil: constant

Input data

Observed atmospheric climate data sets used: GSWP3, PGMFD v2.1 (Princeton), WATCH (WFD), WATCH-WFDEI

Climate variables: tasmax, tasmin, wind, rhs, pr

Spin-up

Was a spin-up performed?: Yes

Natural Vegetation

Natural vegetation partition: Static Landuse

Management & Adaptation Measures

Management: Management for agriculture crop (Irrigation and fertilization, both at auto)

Extreme Events & Disturbances

Key challenges: Outputs are at daily time step (as the inputs), therefore reproducing flood extreme may not be meaningful

Additional comments: Elevation bands (10 bands) was used and Temperature lapse and precipitation lapse rate were used

Methods

Potential evapotranspiration: Penman-Monteith, Hargreaves, Priestely-Talyor

Snow melt: Degree-day method

Routing

Runoff routing: Muskingum method
