sediment concentration and accumulative sediment-runoff in slope lengths of 20
40
60m were analyzed based on field simulated rainfall experiments.Results showed that maximum sediment transport rate occurred in 40m slope length at rainfall intensity less than 2mm/ min
while it occurred in 60m slope length at rainfall intensity greater than 2mm/min.Max imum sediment concentration was always observed in 20m slope length in all the experiments.Accumulative sediment-runoff was prone to be steady with time.The study implies that the measures such as farming along contour
which increases the roughness value of slope and changes slope form
should be taken to reduce high sediment concentration and sediment transportrate
and thus control soil and water loss on loess slope.
