Note: Max. CS for the Zimbabwe sub-basins (GWA3 to MAP4) do not include the log transformed statistics (i.e. max. value = 2) and the behavioural ensembles are further constrained by the number of months of zero flows. The behavioural ensemble members for sub-basins with maximum CS values of >3.2 are chosen as those with CS values of >0.05*MaxCS, the others are chosens as those with CS values of >0.1*MaxCS (to obtain enough behavioural ensemble members to analyse the range of different process proportions).
