Book Description
This report presents results from physical and numerical model tests on the effects of the proposed I-664 James River Bridge-Tunnel complex on (a) sedimentation in the federally maintained channels (Newport News, Norfolk Harbor, and Elizabeth River); (b) general sedimentation in the lower James River; (c) changes in overall flushing characteristics; and (d) changes in current velocities and flushing near the Craney Island disposal site. The navigation channel sedimentation was evaluated using the TABS-2 finite element numerical models RMA-2V for hydrodynamics and STUDH for sedimentation with an existing numerical mesh of the Elizabeth River and lower James River areas. For the general sedimentation investigation, a new numerical mesh was created and the same numerical models, RMA-2V and STUDH, were used. Data for the flushing and currents evaluation were provided by the Virginia Institute of Marine Science. Results from the physical model tests indicate circulation changes will be localized with minimal effects on the general circulation of the lower James River. Results from the numerical sedimentation modeling indicate that sedimentation will be generally unchanged or reduced except on either side of the north island where increases can be expected. The areas experiencing unchanged or slightly reduced sedimentation rates include the oyster grounds, the Elizabeth River and Norfolk Harbor Channels, and the Newport News Channel. (fr).

Book Description
Hopewell, Virginia is a highly industrialized city, the Celanese Corporation of America, the Continental Can Company, the Hercules Powder Company and the Solvay Process Division of Allied Chemical and Dye Corporation having plants there. All of these plants have industrial and human wastes, the combined amount of which is great from the standpoint of both volume and strength. In addition, there are human wastes from the City cf Hopewell and its suburbs in Prince George County and from Camp Lee. All of those wastes, sewage and industrial are discharged into the James River, Bailey Creek and into other tributaries of the two. Primary treatment is given the wastes at Camp Lee; the others are discharged untreated. The location of all discharges in the Hopewell vicinity are shown in Figure I. With the exception of Bailey Creek, the impact of these wastes on the streams they enter was largely unknown, prior to this study. For many years Bailey Creek has been organized as an open sewer. Following passage of the Virginia. State Water Control Law in 1946, the Hopewell industries all began programs leading to reduction of wastes they discharged. In order for them to determine the extent to which such reductions must ultimately be carried, it soon became apparent that information was needed regarding the effect of their wastes on the James River. During the summer of 1951 the Hopowell Industries, through the Hopewell Manufactures Association requested the Water·Control Board's help in making a study of the stream in the Hopewell vicinity in an attempt to answer this question. The Board's staff agreed to lend such assistance as was possible, and the initial phases of such a study were completed during the period August 6 - September 6, 1951.
