Book excerpt: The Virginia Institute of Marine Science (VIMS) team has applied a 3D unstructured-grid hydrodynamic model SCHISM in the study of the impact of channel dredging on hydrodynamics in the lower Chesapeake Bay project area. This report is a companion report to that of Zhang et al. (2017; doi:10.21220/V5MF0F) and focuses on the impact of channel dredging specifically under the projected future sea-level change (SLC) of 1 meter rise by 2100. This is an average of the high end of semi-empirical, global sea-level rise (SLR) projections adopted by the Virginia Port Authority (VPA) and the Army Corps of Engineers, Norfolk District, for the evaluation. From a tidal dynamics point of view, the 1-meter mean SLR increases the water depth in the channel and also increases the horizontal extent of the Bay water coverage.
