Abstract
Analysis of High-Resolution Numerical Simulations of the James River Estuary in Support of the USRS Project (continuation of ONR Grant N000141812750.The goal of this project is to analyze hindcast numerical simulations of the James River Estuary to provide a predictive understanding of the surface and sub-surface hydrographic features that were observed during the April 2019 USRS experiment. A unique data set that includes in-situ ship-based measurements, data collected from multiple coordinated autonomous underwater vehicles, and remote sensing imagesprovided unprecedented three-dimensional resolution of the density and velocity fields in a region of complex estuarine bathymetry. The model, which reproduced many of the observations with high fidelity, will be used to improve the basic understanding of the physical processes that result in the frontal features that were observed. Output from the numerical model will be used to test algorithms that estimate the estuarine bathymetry from remotely sensed surface velocity. This effort also will include the development of higher resolution (~10m in the horizontal) nested grid to examine the effect of small-scale bathymetric variations associated with the Monitor-Merrimack tunnel.
