Description :
This study examines recent floodplain deposits throughout the Cape Fear River basin in North Carolina to address downstream changes in mineralogy and the signature of alluvium from Piedmont and Coastal Plain sources. The results indicate that sediment transport in the Coastal Plain is highly dependent on particle size. Sand in the estuary is derived from local blackwater sources, but much of the fine silt and clay is delivered by brownwater rivers that drain from Piedmont sources.
