Abstract : In this report a mathematical study of the tidal motion in the St. Lawrence River and Estuary is presented. Three different types of finite-difference models are discussed in detail, one explicit scheme and two implicit schemes. The differential equations are derived and methods of schematization are discussed. Subsequently, for each of the models the finite-difference equations, the methods of solution, stability, convergence, and final results are given and the models are compared as to their relative advantages and usefulness.
