Abstract: The existing comprehensive fixed-bed model of James River was used to determine the effects of the proposed Elizabeth River dike on tides, currents, salinities, and shoaling in the Elizabeth River channel. The test results consist of measurements of tide heights, current velocities, salinities, and shoaling quantities. From these data it was concluded that the proposed dike had little effect on tides, currents, or salinities in the problem area. In the model, the major source of sediment moving to and depositing in the Elizabeth River channel was found to be the shallow-water area between the Craney Island disposal area and the Newport News Channel. If this area does, in fact, constitute the major source of Elizabeth River channel shoaling in the prototype, the annual shoaling rate in the channel will be greatly reduced by construction of the dike; and the shoaling in the slips will be increased slightly. It is recommended that consideration be given to radioisotope or other tracer techniques to determine the source of shoaling in the Elizabeth River channel, provided an analysis of benefits and costs indicates that construction of the dike would be economically feasible.
