Examples of Sensitivity (cont)
nLow sensitivity
-Slope length at flat slopes (0.5%) A= 4.6 t/a at k = 150 ft, 5.2 t/a at k = 500 ft, 5.5 t/a at k = 1000 ft
nModerate sensitivity
-Slope length at steep slopes (20%) A = 129 t/a at k = 50 ft, A = 202 t/a at k = 100 ft, A = 317 t/a at k = 200 ft.
These results how sensitivity to a variable depends on the situation and illustrates how one need not be concerned with estimating a variable under one condition but give much greater care under another condition.

For example, being off in slope length by 850 ft didn’t have much effect on a 0.5% slope, but being off just 50 ft had a tremendous effect on a 20% slope.
