High Resolution Modeling of the James River Estuary in Support of the USRS Project

Abstract

The overall goal of this project is to develop a high-resolution numerical circulation model of the James River estuary in support of the USRS Project. The primary James River model was developed as a nested grid within an existing and extensively validated model of Chesapeake Bay. A second higher resolution nested grid was developed and successfully used to simulate the April 2019 USRS experiment. The new higher resolution model focuses on Newport News Point, with horizontal resolution of 17m. This horizontal resolution is roughly the same as the water depth, and realistically resolves the bathymetry of the region, including the complex variability associated with Monitor-Merrimack bridge-tunnel. Including this high-resolution bathymetry has improved the models ability to simulate many of the easily observable surface fronts in the region and has increased model skill in simulating both in-situ and remotely sensed data.
