Reduction of Shoaling in Charleston Harbor and Navigation Improvement of Cooper River, South Carolina. Hydraulic Model Investigation

摘要

The existing comprehensive fixed-bed model of the Charleston Harbor system was used to conduct several special-purpose studies. These studies involved a proposed silt trap in Wando River, salinity investigations, a proposed spoil area dike, a scheme to redivert powerhouse discharge from Cooper River into Wando River, intermittent powerhouse operation to meet peak demands, and a proposed extension of the existing navigation channel in Cooper River. In general, model tests were conducted to determine the effects of the several proposals on tides, currents, and salinities throughout the estuary, and test results consist primarily of measurements of tide heights, current velocities, salinities, time-exposure photographs of surface current patterns, graphic illustrations of dye dispersion, and analyses to determine flow predominance.
