Abstract—Marine water quality model plicated because of investment. The application of data-assimilation method is
its multi-parameter and multi-response characteristic. In this limited (Ma, 2005).
paper, a new method based on data-driven model (DDM) is
developed to retrieve the value of model parameters for model The present paper aims to develop a more practical
calibration. All training data are calculated by numerical water technique for optimal estimation of model parameters for
quality model from results of multi-parameter matching design model calibration. In this technique, optimal parameters are
cases. The basic idea is to find out the relationship between model estimated by data-driven model (Solomatine, 2002) which is
parameters and the pollution concentration values of interior based on artificial work. Osaka Daigaku Estuary
