The model parameters other than the outlet coefficients are determined by trial and error along with the automatic calibration procedure. The period of computation covers ·the calibration from 1973 to 1975 and the verification from 1976 to 1977. Both calibration and verification results are found to be quite satisfactory. The effects of different initial assumed values of outlet coefficients through the automatic calibration procedure has been analyzed. The effects of assumed initial storages in each tank on the computed hydrographs have also been studied. The sensitivity analysis on the effects of model parameters other than the outlet coefficients have also been carried to understand more about the effectiveness and characteristics of each parameter on the computed hydrographs. It is concluded that the automatic calibration procedure of the tank model works efficiently and can be used in general practice.
