Two‐Dimensional Branching Salt Intrusion Model

Publication: Journal of Waterway, Port, Coastal, and Ocean Engineering
Volume 109, Issue 1

Abstract

A two‐dimensional (in a vertical plane) branching model is developed to simulate salinity distribution in complex estuaries. The model is applied to a one‐month salinity study in the Chesapeake Bay during a period of low freshwater discharges from the Susquehanna River. Model results compare well with observations in the prediction of depth‐averaged salinities as well as vertical salinity profiles. Simulation of a hypothetical flow reduction suggests significant salinity increase near the head of the bay, and a stronger bottom salt intrusion over the entire bay.
