—This paper presents a large scale hydrological
model for the Fitzroy Basin using the MIKE 11 NAM modelling
system. This model simulates the rainfall runoff processes for
the three different and interrelated storages which are surface
storage, root zone storage and groundwater storage. The
parameters of such model cannot be obtained directly from
measurable quantities of catchment characteristics. Hence
model calibration is required to get the model parameters.
Manual calibration is very time consuming and it only focuses
on a single objective function. Thus tradeoff exists between the
different objectives. For this study, an automatic calibration
was done considering the four multiple objectives and obtained
the optimal values of the model parameters for each catchment.
The simulated and observed discharge hydrographs show a
reasonable good match for each sub-catchment. Moreover
model reliability was evaluated using the statistical methods
Index of Agreement (IA) and Efficiency Index (EI). The IA and
EI obtained 0.821-0.951 and 0.849-0.961 for different
—Basin, catchment, calibration, hydrological
model, MIKE 11 NAM.
