Abstract: A method for the estimation of the parameters of generalized Streeter-Phelps river quality models is developed in this paper. The method is quite flexible since it does not require any uniformity in the geometry of the measurement points and can be used in the case in which only DO data are available. The validity of the method is tested by means of real data collected on the Bormida river in northern Italy, and the corresponding results and difficulties are pointed out. Finally the sensitivity of the method with respect to missing data is analyzed.
