Figure 4.3 Rural Piedmont Regional Curve with Surveyed Bad@l Cross-SectionAreas for the Tributary to Fork Creek, Tributary to Sandy Creek, West Branch Tibbs Run and Project Reaches. (Project data points were not used in determining the regression line.) (Harmun et al., 1999)
In order to verify that the Piedmont regional curve is appropriate to use in this region, we compared data from three reference reaches in the NCDOT reference reach database. These three streams, Tributary to Fork Creek, Tributary to Sandy Creek, and West Tibbs Run, are all located in the Cape Fear River Basin within Randolph County. The reference reaches show additional points in the vicinity of the project area that were not used to determine the regression line. As indicated in Figure 4.3, each of the reference reaches falls within the 95 percent confidence interval. The Tick Creek gage station, surveyed for the rural piedmont regional curve regression line, is also located approximately 20 miles from the restoration site and agrees with the regional curves. Vegetation The riparian areas of Reaches UT1, UT2, and M1 have been cleared to expand grazing areas for cattle. Only a handful of tnees are found along the streaJn bank, primarily black willow (Salk 4.4
