Some times complex slopes
have a flat section in the middle of them that causes deposition. This deposition is also remote deposition
because it occurs some distance from where the sediment was detached.
|
|
Soil loss occurs at to two
locations on the slope, one on the upper end of the slope and one on the
lower portion of the slope.
|
|
RUSLE2 can estimate soil on
both sections of the slope and it computes the deposition that occurs in the
middle of the slope.
|
|
Applying RUSLE2 to compute
soil loss on the upper of the slope is the same as applying RUSLE2 to a
simple slope.
|
|
Soil loss on the lower
portion of the slope depends on runoff that originates over the entire slope
length.
|
|
Sediment yield (sediment
delivery) for this slope is also less than soil loss because of deposition.
|
|
Sediment yield= Soil loss -
Deposition
