Runoff on undisturbed hillslopes only occurred when storm precipitation exceeded 2--3 cm, while only 0.3 cm was needed to generate runoff from unpaved roads. Runoff coefficients for the undisturbed hillslopes averaged 3% and had a maximum of 8%,

Streambanks produced sediment at a rate of 10 kg m-2 yr-1, and treethrow produced 0.17 tons per kilometer of stream per year. Annual sediment production rates from undisturbed hillslope plots ranged from 1--27 g m-2, while mean rates from undist

STJ-EROS is a GIS-based system that uses empirical sediment production functions and delivery ratios to estimate watershed-scale sediment yields. STJ-EROS indicated that unpaved roads are increasing sediment yields by 5--40 times above undisturb
