• Abstract:
  Double-ring infiltrometer tests were used to measure infiltration rates in situ at three sites in the ; Piedmont physiographic province and one site in the Coastal Plain physiographic province of ; Georgia. The accuracy of predicting saturated hydraulic conductivity for Piedmont soils from the ; published soil surveys of the National Resource Conservation Service (NRCS) and the derived ; pedotransfer functions (PTF) was then investigated. ; The major findings of this study include: ; - Predicted values from the NRCS overestimated every measured value of in situ saturated ; hydraulic conductivity when compared to field values. ; - Predicted values from the ROSETTA pedotransfer software (primarily by soil grain size) ; more closely estimated the saturated hydraulic conductivity of the Piedmont soils. ; - The infiltrometer, which is known to work well in the sediments of the Coastal Plain, also ; performed well in the soils of the Piedmont physiographic province; however, care must be ; taken to ensure proper installation in soils in the Piedmont.
