Abstract: The existing comprehensive fixed-bed model of James River was used for tests designed to determine the effects of the first and second phases of proposed shipyard expansion of the Newport News Shipbuilding and Dry Dock Company facilities on tides, currents, and adjacent ship channel shoaling. The test results consist of comparable measurements of tide heights, current velocities, and shoaling quantities for existing and proposed conditions. An analysis of the results of the model tests led to the conclusions that the proposed expansion at Newport Nevrs would have no significant effects on current velocities or tidal heights. The maximum increases in current velocities caused by the proposed expansion occurred in and adjacent to the navigation channel at bottom depth at sta 2A and 2 where ebb current strengths were increased from about 1.0 to 2.0 fps. Current directions in the adjacent reach of the James River navigation channel should be improved somewhat after completing the second phase. Shoaling rates in areas adjacent to the dock showed increases ranging from 1.5 to 2.5 times the rates with base conditions installed, with the maximum shoaling rate occurring with plan 2 installed. However, the quantities involved are comparatively small and the indicated increases should not be considered a significant deterrent to the proposed expansion.
