Maintenance Dredging Of Georgetown Harbor Georgetown County South Carolina PDF Download

The Georgetown Harbor model, a fixed-bed model constructed to linear scale ratios of 1:800 horizontally and 1:80 vertically, reproduced a portion of the Atlantic Ocean, Winyah Bay including Mud Bay, North Inlet and marshes between Winyah Bay and North Inlet, the Sampit River including Georgetown Harbor, and the lower portions of the Pee Dee, Black, and Waccamaw Rivers and adjacent marshes. The model was equipped with necessary appurtenances for the accurate reproduction and measurement of tides, tidal currents, salinity intrusion, freshwater inflow, and shoaling distribution. The purposes of the model study were (1) to determine the effects on the hydraulic, salinity, and shoaling characteristics of a deepening from 27 to 35 ft of the main navigation channel to Georgetown Harbor and (2) to determine if present maintenance dredging can be reduced by proposed plans involving channel revisions, sediment traps, and freshwater flow diversion. These studies will be reported in later reports. Model verification tests, presented in this report, were conducted to ensure that the model hydraulic, salinity, and shoaling characteristics were in satisfactory agreement with those of the prototype. The agreements attained between model and prototype were considered satisfactory for the types of tests conducted in the model. (Author).
