Automatic calibration of tank model : in Ping River Basin, Thailand Bangkok : Asian Institute of Technology, 1980 viii, 109 p. Thesis ; no. WA-79-4 A thesis submitted in partial fulfillment of the requirements for the degree of Master of Engineering, School of Engineering and Technology Thesis (M.Eng.) - Asian Institute of Technology, 1980 An automatic calibration procedure is applied to calibrate the outlet coefficients of the tank model for humid region which is constructed to describe the rainfall-runoff relationship of the upper Ping river basin above Ban Tha Sala gaging station, Thailand. 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.
