Abstract: A new mathematical modeling approach for predicting the concentrations of water quality constituents in an estuary has been developed. The model foundation is a two-dimensional partial differential equation describing the transport process in the estuary. The discretized version of a steady-state model is reformulated as a large dimensional linear matrix equation whose solution is obtained by an efficient iterative procedure. An analytical criterion for calibration is considered and the agreement of the matrix model solution with field data is examined. The model is calibrated with data for total phosphorus collected in two periods in the fall of 1972 from 18 sampling stations in Corpus Christi Bay. Numerical analysis of the matrix model is presented and its performance is compared with another phosphorus model for the Corpus Christi Bay system. This approach provides a simple structure for the model that is ideally suited to water quality management analysis.
