The prediction or forcast of water quality of lakes is one of the important parts of water quality control techniques. In near future, there may be chances of changing of the water quality of the Lake Biwa, because of the regional development depending upon the Lake Biwa Comprehensive Project. For the quantification of the changes, the finite element model has been developed to simulate and predict the possible changes of the water quality. The deduction processes of the finite element equations from the shallow water equations and the water quality equation are fully described and some related cares are noted in this paper. The applications of the proposed method to the southern part of the Lake Biwa and the practicability of the model will be discussed together with the observed data in the comming publication.
