- Model for continuous strearnflow simulation, namely Rainfall-Runoff Model PLN-PPE Release 01 has been developed by Faculty of Engineering Gadjah Mada University, through cooperation with Engineering Service Centre of National Electricity State Owned Enterprise (PLN-PPE). In order to improve efficiency of the use of model, particularly on calibration procedure, catchment parameter values were optimized using "Gauss-Newton" search algorithm. � In this research, optimization was done for both of calibration and verification model, based on the data collected from upstream Serayu catchment area at central ofJava. For the preliminary research, four of ten parameters were optimized using three set of initial values. As result, the accuracy of model output which were measured by annual volume error (VE), correlation coefficient (R), and mean of relative error (RE) between computed and observed discharges could be increased. All of the optimized parameters proved be converge on the same .final optimum values. By such approach, computation tune needed to carry out model calibration can be reduced significantly because the initial values of some calibration parameters are determined automatically
