Abstract:

A nearshore hydrodynamic and sediment transport model was developed to simulate synthetic storms with design SLR scenarios surrounding the military installations in Norfolk, Virginia. Foreseeable risk and effect of storm surge damage accompanied by waves, tides, and Sea Level Rise SLR were examined. The final results include the evaluation of impacts for five SLR 0.0, 0.5, 1.0, 1.5, and 2.0 m and three storm conditions 50-yr, 100-yr return tropical storms, and a winter storm. Associated with the storm surge and SLR, extensive inundation will occur at the Naval Station Norfolk, approximately 70-80 of the Naval Station Norfolk under the 2-m SLR scenario. The calculated morphology changes indicate that the sediment movement mostly occurs in the navigation channels and the maximum depth changes are more than 3.0 m along the channels. The bed volume changes show that the storms induce a net volume loss within the channel area, an indication of channel flushing in the study area.
