In the original publication the first sentence starting with “The model calibration process…” in Sect. 3.2.3 Model calibration and validation should be amended as,
“The model calibration process refers to an estimate of the model parameters to fit the model results to a set of observed data, while the validation process refers to an evaluation of the results of the model outputs using the calibrated model parameters compared to the observed outcomes [13].”
