Figure 4 . (a) Daily time series of discharge, when calibrating
the model with six different variables. (b) Time series of the six
variables when calibrating the model with discharge observations only
(discharge, water level, flood extent and soil moisture are at a daily
time step, while TWS and ET are at a monthly time step). KGEiniis the mean KGE of initial runs, KGEcal is the mean KGE of
calibrated runs, evaluated for the same period of calibration,KGEeval is the mean KGE of calibrated runs, evaluated for a
different period than calibration. Time series for all variables by
calibrating the model with all setups is presented in supporting
information (Figure S1).
