Calibration parameters and their order of sensitivity with and without the involvement of biophysical parameters. Respective initial ranges and the spatial scale of iteration are shown in Table A1 (Appendix A). See Neitsch et al. (2011) for parameter definitions, except GIW_K; GIW_K is a new SWAT parameter for surface depressions (Evenson et al., 2016). ** Calibration was discontinued after the first batch of iterations; *** these parameters were not calibrated in M1[Basic].
