Abstract
The Waccamaw River Basin is located in the coastal plain and meanders from North Carolina to South Carolina. This tidal black-water river flows parallel to the coast past the cities of Conway and Georgetown, terminating in Winyah Bay. The river is hydrologically connected to the Atlantic Intracoastal Waterway (AIW) and experiences semi-diurnal tides with a range classified as micro-tidal (< 6.5 feet). The semi-diurnal tidal amplitude in the Waccamaw River declines with increasing distance upstream from Winyah Bay and the AIW. Temporal variations in the longitudinal tidal gradient of Winyah Bay, AIW, and the Waccamaw River reflect varying effects of astronomical tides, weather, and streamflow.
