Flow duration curves simulated by the models
Calibration of hydrological models using flow duration curves
... Hydrologic models are simplified conceptualisations of the hydrologic processes in a catchment. Such simplifica- tions will necessarily lead to errors in the way the struc- ture of the model represents the ...
