Analytical Model for Surface Saltwater Intrusion in Estuaries

ABSTRACT Ye, R.; Song, Z.; Zhang, C.; He, Y.; Yu, S.; Kong, J., and Li, L., 2017. Analytical model for surface saltwater intrusion in estuaries. Based on the laterally averaged salt transport equation, a physically based surface saltwater intrusion model is presented for estimating the spatial distribution of salinity near the surface of the river along the estuary over high-water slack, low-water slack, and tidal-average conditions. The model is applied to simulate steady-state salinity profiles on the water surface of the Modaomen Estuary of the Pearl River delta in China. The results indicate that this model describes the surface salt profiles reasonably well and is capable of forecasting surface saltwater intrusion.
