-
R code of the model is provided in simplemodel.R
- SWBM set up to compute hydrology at site Payerne
- sections concerning delayed runoff are commented out
- the delyed runoff requires an additional parameter and takes more time to compute
- it is required if daily runoff should be analyzed
- it is not required if the focus is on soil moisture, ET, or monthly runoff
-
R code of to plot simple model output is provided in figures.R
-
The model is tested with R Versions >= 2.10
-
Meteorological input data file required to run simplemodel.R:
./Data/pay_meteo_1998-2012.txt
- Input data files required to run figures.R:
./SoilMoisture_SimpleModel_Payerne_1998-2012
./Data/PAY_SM_2008-12.txt

Execute model with default parameters and create standard plots (make sure to create directory ./fig
beforehand)
output = simplemodel( exp_runoff=6.4, exp_et=0.06, beta=0.66, whc=220, melting=3 )

Model is introduced in:
- Orth, Koster, Seneviratne 2013, J.Hydrometeorol. (based on Koster and Mahanama, 2012, J.Hydrometeorol.)
-
Modifications to the model described in
- Orth et al. 2015, J.Hydrol [update to snow module]
- Orth and Seneviratne, 2015, ERL [accounting for dew formation]
- Precipitation
- Net Radiation
- Temperature
- Soil Moisture
- Runoff
- Evapotranspiration
- Snow Water Equivalent
-
local-scale: using streamflow observations from near-natural (usually rather small) catchments
- applied in Orth et al. 2015, J.Hydrol & Orth and Seneviratne, 2014, Clim.Dyn & Orth et al. 2013, J.Hydrometeorol.
-
continental-scale: using multiple hydrological reference datasets
- applied in Orth and Seneviratne, 2015, ERL & Orth et al., 2016, Scientific Reports
-
continental-scale calibration (applicable all over Europe):
- exp_runoff = 3.89, exp_et = 1.14, beta = 0.674 (maximum of normalized ET function), whc = 970.5 [mm], melting = 10.39 [mm snow water equivalent per degreee C above 1 deg C]
