There is widespread agreement that good correspondence of measured and calculated streamﬂow at the catchment outlet is not a sufﬁcient criterion for the validity of a physically based hydrologic model, but that additional knowledge concerning catchment-internal processes is needed (e.g. Beven, 1989). Yet, for many catchments such information is not available and the model’s performance can only be assessed by comparing calculated and measured streamﬂow. However, the information provided by a hydrograph is not limited to the absolute height of the runoff. For example, a separation of the hydrograph allows for identiﬁcation of runoff components originating from different compartments of the considered system, and responding differently delayed and smoothed to rainfall events. An example of the potential beneﬁt of this information for model
veriﬁcation has been given by Eckhardt et al. (2002).
