Explanatory variables used in the South Carolina study (see paper for description)									
									
"The analysis for the State of South Carolina included sites from North Carolina and Georgia, and the whole area was divided into four hydrologic regions with three binary variables (Z1, Z2, Z3) as follows: Blue Ridge (0, 0, 0), Piedmont (1, 0, 0), Upper Coastal Plain (0, 1, 0), and Lower Coastal Plain (0, 0, 1) "									
									
"Numbers below are real values of: (1) Drainage area, A, in squared miles; (2) main channel slope in feet per mile; (3) length of the main channel in miles; (4) the mean basin elevation in feet above sea level; (5) annual mean precipitation in inches at the centroid of the basin; (6) annual mean runoff in inches at the centroid of the basin"
