5203 |a"A simple mathematical model of the Fraser River salinity intrusion is presented which is designed to be suitable for microcomputer applications. One of the novel features of the model is that it allows for landward migration of the boundary between fresh and sea water on the flood and thus is relevant to low river discharge conditions (Q <3000 m³/s) as well as higher flows. The model is applied to the main arm of the Fraser River Estuary by assuming a trapezoidal cross-section with an average breadth of 350 m, surface width three times the bottom width and a bottom drag coefficient of 1.0 x 10⁻³ and to the north arm by assuming a rectangular cross-section. Fifteen sets of observations of the intrusion of the salt wedge and its maximum excursion in the main firm reported by Ages (1979) and Geyer (1985) are compared to modelled results based on measured river discharges at Hope and semi-diurnal tides at Pt. Atkinson over river flow conditions ranging from freshet to low flow. Although the agreement is reasonable it could likely be improved by including forcing from diurnal tidal constituents"--Abstract.
