“…Measurements or estimates of erosion rates on cropland typically range from 5 to more than 30t ha ±1 a ±1 (Beasley, 1979;Dendy, 1981;Sheridan et al, 1982;Lowrance et al, 1986Lowrance et al, , 1988Cooper et al, 1987;Phillips, 1993Phillips, , 1997Phillips et al, 1993;Slattery et al, 1997), while sediment yields of coastal plain streams are, at least an order of magnitude lower (Dole and Stabler, 1909;Kennedy, 1964;USDA, 1979;Simmons, 1988;Hubbard et al, 1990;Kim, 1990). The disparity between sediment eroded from hillslopes and fluvial sediment yields is well known and occurs in a variey of environments, but is often particularly evident in the coastal plain.…”
