Historical erosion from agricultural fields with subsequent deposition in riparian systems has resulted in a pronounced landscape feature in the upper Coastal Plain physiographic area. Erosion of soil particles and aggregates on cropland with downslope transport by runoff water has resulted in deposition of larger and heavier material that entered riparian areas. This forms terrace-like deposits at the lower edges of fields (Figure a). Continued deposition year-after-year further results in flow restrictions that have to be removed to prevent encroachment into the field. Roadways and/or turn rows are common on these deposits, which require periodic grading or removal.
