A numerical model is presented for the computation of flow variables in a well-mixed estuary. The numerical method used is an implicit unconditionally stable finite difference scheme, of second-order accuracy. Data are presented for the scheme in a physically realistic way, to avoid nonlinear instabilities, and for this purpose the dynamic equations are written in pentadiagonal form and solved with a generalized double-sweep algorithm.
