Slope–channel linkage and sediment delivery on North Carolina coastal plain cropland

This paper presents the results of field measurements conducted in a small (19Ð4 ha) agricultural basin on the North Carolina coastal plain. The overall objective of the study is to determine the magnitude of soil erosion and sediment delivery as a result of storm runoff. The results suggest that erosion in the region is more rapid and extensive than previously thought. Fields at the site are experiencing accelerated soil loss, with rates often comparable to those of the southeastern Piedmont, a region long recognized as having rapid and problematic soil loss. This casts doubt on some assessments of the coastal plain as being a stable, non-eroding landscape. However, much of the soil mobilized is redistributed and stored within the watershed with only a small portion of the soil eroded from slopes leaving the basin on an event time frame.
