Calibration is a necessary process for rainfall-runoff models. A fuzzy multiobjective function (FMOF) was proposed to combine various objective functions using only three important features of a hydrograph (i.e., time to peak flow, peak flow, and total runoff volume) for model calibration. A distributed storm-event rainfall-runoff model was used in the study to show how to use FMOF for different applications. The results reveal that FMOF using only three features of a hydrograph for model calibration, not a whole hydrograph, has a performance equivalent to that of the conventional single objective function.
