Salt-water intrusion in the Fraser River estuary was modeled numerically and compared with a field measurement program. The salt wedge was observed to have a highly dynamic behavior and yet to retain its stratified character. The main physical and computational problems studied were: (1)The interfacial stress term; (2)the necessary boundary conditions at the river mouth; and (3)the computational stability.
