Newport News Channel Deepening Study, Virginia. Numerical Model Investigation

Abstract

This report presents results from the numerical model investigation whose primary objective was to evaluate general changes in circulation, currents, and sedimentation associated with the overdeepening of the Newport News Channel. An additional objective of the study was to assess the effects of the overdeepening on the reported estuarine circulation cell (flow convergence) off Hampton Flats and Newport News Point. Three alternative plans of overdeepening, 57, 64, and 70 ft, were evaluated. This numerical model investigation used the TABS-2 finite element numerical models RMA-2V for hydrodynamic analysis and study for sediment transport computation with a modified version of an existing numerical mesh (expansion plan B) of the lower James River.
