WATER EROSION PREDICTION AND CONTROL
The Revised Universal Soil Loss Equation (RUSLE) is used to estimate interrill (sheet) and rill erosion
caused by water. RUSLE is an erosion model designed to predict the long time average annual soil loss
carried by runoff from specific field slopes in specified cropping management systems. RUSLE provides
a method for determining the right combination of land use and conservation practices that will result in
satisfactory water erosion control on each specific site.
Sheet and rill erosion can be controlled by using one or more conservation practice. In Michigan, the
following practices are applicable: conservation cropping system, conservation tillage system, contour
farming, contour stripcropping, cover and green manure crop, critical area planting, crop residue
management, diversions, terraces, or a change in land use.
The computer version (1.05) of RUSLE was used to develop many of the erosion prediction tables.
RUSLE is available and distributed from the Soil and Water Conservation Society, Inc. under a
Cooperative Research and Development Agreement with USDA-ARS.

WATER EROSION EQUATION A = RKLSCP
A = predicted average annual soil loss (tons/acre year)
Soil loss can be predicted on any field condition where soil erosion by water is probable.
R = rainfall-runoff erosivity factor. It is the average annual summation (EI) values in a normal year's
rain. The erosion-index is a measure of the erosion force of specific rainfall. When other factors are
constant, storm losses from rainfall are directly proportional to the product of the total kinetic energy of
the storm (E) times its maximum 30-minute intensity (I). Storms less than 0.5 inches are not included in
the erosivity computations because these storms generally add little to the total R value. R factors
represent the average storm EI values over a 22-year record. R is an indication of the two most important
characteristics of a storm determining its erosivity: amount of rainfall and peak intensity sustained over
an extended period.
The erosivity of rainfall varies greatly by location. The R factor in Michigan ranges from 75 to 135.
Approximately 70 percent of the erosivity occurs in the months of May, June, July, and August in
Michigan.
K = soil-erodibility factor. It is a measure of erodibility for a standard condition. This standard
condition is the unit plot, which is an erosion plot 72.6 ft long on a 9 percent slope, maintained in
continuous fallow, tilled up and down hill periodically to control weeds and break crusts that form on the
surface of the soil. The plots are plowed, disked, and cultivated the same for a row crop of corn or
soybeans except that no crop is grown on the plot.
The soil erodibility factor K represents both susceptibility of soil to erosion and the rate of runoff, as
measured under the standard unit plot condition. Fine textured soils high in clay have low K values,
about 0.05 to 0.15, because they are resistant to detachment. Coarse textured soils, such as sandy soils,
have low K values, about 0.05 to 0.2, because of low runoff even though these soils are easily detached.
Medium textured soils, such as the silt loam soils, have moderate K values, about 0.25 to 0.4, because
they are moderately susceptible to detachment and they produce moderate runoff. Soils having a high silt
content are most erodible of all soils. They are easily detached; tend to crust, and produce high rates of
runoff. Values of K for these soils tend to be greater than 0.4.
In Table 4, there are K and Kf factors listed for each soil series. The K for a soil series may vary by soil
type. K factors are developed from a soil nomograph representing.soil properties that influence
erodibility by water: texture, organic matter, structure, and permeability. These are the major factors that
affect the infiltration rate and the total water capacity of a soil. The soil nomograph rates each factor and
is used along with Soils 5 data for each soil type to select a K factor and estimate how well a soil can
resist the dispersion, splash, abrasion, and transport forces of rainfall and runoff.
Organic matter reduces erodibility because it reduces the susceptibility of the soil to detachment, and it
increases infiltration, which reduce runoff and thus erosion. Addition or accumulation of increased
organic matter through management such as incorporation of manure is represented in the C factor rather
than the K Factor. Extrapolation of the K factor nomograph beyond an organic matter of 4 percent is not
recommended or allowed in RUSLE. In RUSLE, factor K considers the whole soil and factor Kf
considers only the fine-earth fraction, the material of <2.00mm equivalent diameter. FOR MOST
SOILS Kf=K.

EROSION PREDICTION-WATER-5
However, rock fragments are not taken into account in the nomograph or the RUSLE equation. If rock
fragments are substantial, they have an armoring effect, and the K factor should be adjusted downward.
Therefore, K will be less than Kf because armoring is comparable to mulching in the C factor, i.e. there is
less splash erosion on gravelly soils. For example, from Table 4, Water 16.4, is the Boyer soil series. A
Boyer sandy loam soil type has a Kf of 0.24 and a K of 0.24. Kf equals K. A Boyer gravelly sandy loam
has a Kf of 0.24 and a K of 0.17. Use the K of 0.17 to make the erosion prediction. K is less than Kf on
this soil.
Soil structures affects both susceptibility to detachment and infiltration. Permeability of the soil profile
affects K because it affects runoff.
Although a K factor was selected to represent a soil in its natural condition past management or misuse of
a soil by intensive cropping can increase a soil's erodibility. The K factor may need to be increased if the
subsoil is exposed or where the organic matter has been depleted, the soil's structure destroyed or soil
compaction has reduced permeability. A qualified soil scientist can assist in making this interpretation.
L = slope length factor. Represents the effect of slope length on erosion. It is the ratio of soil loss from
the field slope length to that from a 72.6-foot length on the same soil type and gradient. Slope length is
the distance from the origin of overland flow along its flow path to the location of either
concentrated flow or deposition. See Figure 1. Fortunately, computed soil loss values are not
especially sensitive to slope length and differences in slope length of + or - 10 percent are not important
on most slopes, especially flat landscapes.
Slope lengths are best determined by visiting the site, pacing out flow paths, and making measurements
directly on the ground. Obtain L by measuring perpendicular to the contour from the point of origin of
overland flow to where deposition begins or runoff enters a well defined channel. Contour maps having
intervals greater than 2 feet should be used cautiously, if at all, to determine slope lengths. Slope length
values are generally too long when contour maps are used to choose slope length. Slope lengths usually
do not exceed 400 feet. Slope lengths longer than 1,000 feet should not be used in RUSLE because the
reliability of RUSLE at these long slope lengths is questionable, and flow becomes concentrated on most
landscapes before such long slope lengths.

Determining where slope length end can be difficult in Michigan’s glacial topography. Generally it is
necessary to measure several slopes in a field with variable soils. The main areas of deposition that end
RUSLE slope length are at the base of concave slopes. If no signs of deposition are present, the user will
have to visualize where deposition occurs. The slope-ending depositional area on a concave slope is
usually below where the slope begins to flatten.
As a rule of thumb, if no signs of deposition are present on a concave slope, assume that deposition
begins at the location where the steepness is 1/2 of the average steepness of the concave area.
Another difficulty is determining if a channel is a concentrated flow channel that ends a RUSLE slope
length. Channels that collect the flow from numerous rills are generally considered to be slope ending
concentrated flow channels.
S = slope steepness. Represents the effect of slope steepness on erosion. Soil loss increases more
rapidly with slope steepness than it does with slope length. It is the ratio of soil loss from the field
gradient to that from a 9 percent slope under otherwise identical conditions. The relation of soil loss to
gradient is influenced by density of vegetative cover and soil particle size.
LS factors = The slope length factor L computes the effect of slope length on erosion, and the slope
steepness factor S computes the effect of slope steepness on erosion. Values of both L and S equal 1 for
the unit plot conditions of 72.6 ft. length and 9 percent steepness. Values of L and S are relative and
represent how erodible the particular slope length and steepness is relative to the 72.6 ft long, 9 percent
steep unit plot. Thus some values of L and S are less than 1 and some values are greater than 1.
Stripcropping or contouring does not affect the LS value.
In Michigan, three of the four RUSLE LS tables are used to compute LS values. Table 2 is chosen for
most cultivated cropland in row crops and small grains. Table 1 is used for pasturelands and situations
where the soil is consolidated and resistant to rill erosion. Table 3 is for the case where most of the
erosion is caused by rill erosion, which is often the case for construction sites immediately after
disturbance.
C = cover-management factor. The C-factor is used to reflect the effect of cropping and management
practices on erosion rates. It is the factor used most often to compare the relative impacts of management
options on conservation plans. The C-factor indicates how the conservation plan will affect the average
annual soil loss and how that soil-loss potential will be distributed in time during construction activities,
crop rotations, or other management schemes.
The C-factor is based on the concept of deviation from a standard, in this case an area under clean-tilled
continuous-fallow conditions. The Soil Loss Ratio (SLR) is then an estimate of the ratio of soil loss
under actual conditions to losses experienced under the reference conditions.
“C” represents the effects of plants, soil cover, soil biomass, and soil disturbing activities on erosion.
RUSLE uses a subfactor method to compute soil loss ratios, which are the ratios at any given time in a
cover management sequence to soil loss from the unit plot. Soil loss ratios vary with time as canopy,
ground cover, roughness, soil biomass, and consolidation change. A “C” factor value is an average soil
loss ratio weighted according to the distribution of R during the year. The subfactors used to compute
soil loss ratio values are canopy, surface cover, surface roughness, prior land use, and antecedent soil
moisture.

Surface cover is material in contact with the soil surface that intercepts raindrops and slows surface
runoff. The total percent of the surface covered is the characteristic used by RUSLE to compute how
surface cover affects erosion. Surface cover includes all cover that is present, including rock
fragments, live vegetation, cryptograms, and plant residue. The only minimum size requirement
for material to be counted as surface residue is that it either be of sufficient size or attached to the
surface such that it is not removed by runoff.
RUSLE accounts for surface roughness in the C value calculation. Surface roughness ponds water in
depressions and reduces erosivity of raindrop impact and water flow. If the depositions are sufficiently
deep, much deposition occurs in them. Over time, roughness disappears as the depressions fill with
sediment and the soil subsides after the tillage operations that formed the depressions.
Roughness is reduced in RUSLE as a function of cumulative rainfall after the last tillage operation.
Roughness also indicates the degree of clodiness and the likelihood that the surface will seal, producing
increased runoff and soil erodibility. Accounting for roughness, such as with the plow plant tillage
system, is one reason some C values are lower with RUSLE.
If a C factor of 0.15 represents the specified cropping management system, it signifies that the erosion
will be reduced to 15 percent of the amount that would have occurred under continuous fallow conditions.
The C factor in Michigan ranges from 0.005 for continuous grass/hay to 0.50 for continuous row crops
with low residue returned to the soil. C factors are also available for pastureland, wildlife land, idle land,
and woodland uses.
There are four regions representing Michigan’s RUSLE C & K factor zones: 100a, 102a, 102b, and 102c.
Each zone is represented by the following cities for historical weather data as follows: 100a, Marquette,
Michigan; 102a, Gladwin, Michigan; 102b, Grand Rapids, Michigan; 102c, Norwalk, Ohio.
P = support practice factor. The RUSLE P-factor reflects the impact of support practices on the
average annual erosion rate. It is the ratio of soil loss with contouring and/or stripcropping to that
with straight row farming up and down slope.
As with the other factors, the P-factor differentiates between cropland and rangeland or permanent
pasture. Both options allow for terracing or contouring, but the cropland option contains a stripcropping
routine, whereas the rangeland/permanent-pasture option contains an “other mechanical disturbance”
routine. For the purpose of this factor, the rangeland/permanent-pasture option is based on the support
operation being performed infrequently, whereas in the cropland option the support operation is part of
the annual management practice.
T = soil loss tolerance expressed in tons per acre per year.
The “T” value is important in the use of the soil loss equation itself. Soil loss tolerance is the maximum
amount of soil loss, in tons per acre per year, that can be tolerated and still permit a high level of crop
productivity to be sustained economically and indefinitely.
Soil loss tolerance values of 1 through 5 are used. These values represent the tolerable tons of soil loss
per acre per year where food, feed, and fiber plants are to be grown. T values are not applicable to
construction sites or other non-farm uses of the erosion equation.

The RUSLE Adjusted K factors from this table are to be used only for hand calculations prior to the use
of the computerized version of RUSLE in FOCS.
Procedure:
1.
Obtain K for each soil from the K factor data element on the Soil Interpretations Record (SOI-5), or
from the K factor column in the Interpretative Groupings Table in Section II of the FOTG.
2.
From the table above, read the RUSLE Adjusted K that corresponds to the K factor obtained in Step
1. This is the K value to use in RUSLE.

ESTIMATES OF RESIDUE COVER REMAINING AFTER SINGLE
OPERATION OF SELECTED TILLAGE MACHINES
Each tillage or planting leaves a percent of the residue that was present just prior to that operation. The
following tables are classified as being either Non-Fragile or Fragile. See list below . This is a subjective
classification based in part on the ease in which crop residues are decomposed by the elements or buried
by tillage operations. Plant characteristics such as composition and size of leaves and stems; density of
the residue; and relative quantities produced were considered.
Many factors affect the amount of residue left after a pass with a tractor and tillage or planting machine.
Residue levels are sensitive to depth and speed of equipment operation and to row spacing. When
selecting values from the ranges in Table 2 for a specific machine, consider the following general rules of
thumb: (1) At shallower operating depths, greater amounts of residue are left on the surface, while at
deeper operating depths, more residue is buried; and (2) Slower operating speeds tend to leave more
residues on the surface, while at faster speeds more residues are buried. Under some conditions, field
cultivators and other finishing tools with field cultivator gangs and some planters and drills may return as
much as 20 percent of the residue incorporated at shallow depths by recent previous operations. Excess
wheel slippage caused by improper ballasting of tractor tires can destroy valuable residues in the wheel
tracks.
Use the figures as a guide in selecting the types of equipment and types of blades, points or sweeps to be
used in the tillage system. Measure the actual amount of residue being left by the operation and make
adjustments accordingly.

significantly.
FORMULA: Crop Residue Remaining = % residue cover x tillage factors x decomposition rate.
The values in this list can be used to estimate reductions in surface cover that result from one or a series
of tillage or other field operations, when they are calculated and expressed as reductions in percent
ground cover.
The values in this list should not be used to estimate reductions in surface cover calculated and expressed

How To Compute Percent Residue Remaining
To calculate and estimate the percent cover remaining after planting and tilling crop residue, first convert
crop yield to pounds of residue remaining after harvest. Then using the cross reference chart (page 21),
convert to percent cover.
For example, a corn yield of 90 bushels per acre produces 5,040 lbs. of corn residue, which leaves
approximately 82 percent residue cover. Note corn residue is considered to be non-fragile. To compute
the percent cover after planting using the charts, multiply the harvest percent cover times the non-fragile
overwintering factor to get percent cover before planting. 82% x 90% = 73.8% spring cover.
To estimate the percent cover after no-till drilling soybeans in 7” rows with fluted coulters into this
corn residue: multiply 73.8% x 90% = 66.4% corn residue after planting.
To estimate percent cover for a spring chisel/disk operation: multiply 73.8% cover remaining x
chiseling factor (50%) x finishing disk factor (70%) or 73.8% x (50%) x (70%) = 25.8% corn residue
after planting.

ESTIMATING THE COVER AND MANAGEMENT C FACTOR
FOR PERMANENT GRASSES
RUSLE VERSION:
The Time Invariant option in the C factor routine of RUSLE version 1.05pre_d was used to develop the
C factors for established grasses. The inputs needed in RUSLE are identified below.
PERMANENT GRASSES – ASSUMPTIONS:
Long-term or permanent grasses. For grasses established in recent years, the Time Variant option in
RUSLE should be used.
Relatively smooth soil surface. These values may not apply to rough surfaces, such as may occur from
grazing on wet or clayey soils.
Root masses in upper 4 in. of soil surface are 4000# for High, 2500# for Medium, and 1000# for Low.
Since these stands are more permanent than grasses in rotation, they may be less productive and contain
more weeds. The root mass, therefore, will likely be lower than with grasses in long-term rotation with
cultivated crops.
COVER(%):
Total Cover is the sum of ground cover and canopy cover. Note: In this table, total cover does not
exceed 100 percent. It is assumed that ground cover occurring directly below canopy will be counted as
ground cover.
Ground Cover is any material in contact with the soil surface during rainstorms that intercepts raindrops
and affects runoff. It includes live plant material, plant residue, and any other material such as gravel,
stones, etc.
Canopy Cover is plant material, dead or alive, above the soil surface during rainstorms. Canopy
intercepts raindrops but does not affect surface runoff.
Estimating Cover:
The line transect method can be used. Following standard procedures established for measuring crop
residue cover, the line is stretched above the canopy. A “hit” occurs when canopy or ground cover occurs
directly beneath the “point”. When both canopy and ground cover occur below a “point’, only
ground cover is recorded, since it has the greater impact on erosion reduction. After making line
transect measurements in various kinds of cover types, one should be capable of making visual estimates.
Periodic re-calibration with the line transect will likely be needed.

EROSION PREDICTION-WATER-68
VIGOR/FERTILITY/PRODUCTIVITY:
Plant vigor, soil fertility, and crop productivity of the PERMANENT grasses are grouped into classes of
high, medium, and low.
High would be associated with a dense stand of sod-forming grasses with good plant vigor, productivity,
management practices, soil fertility, and soil
quality. A 4000 lb. /ac average annual root mass in the
upper four inches of the soil was used in RUSLE.
Low would be associated with a stand of grass with poor vigor, management, and soil quality, as well as
low productivity and soil fertility. A 1000 lb. /ac average annual root mass in the upper four inches of the
soil was used in RUSLE. The stand would be more open and contain more weeds than stands classed as
Medium and High.
Medium would be associated with a stand that falls between High and Low. A 2500 lb. /ac average
annual root mass in the upper four inches of the soil was used in RUSLE.
ROUGHNESS:
The soil surface associated with PERMANENT grasses is assumed to be relatively smooth. A random
roughness value of 0.24 in. was used in RUSLE.
SURFACE COVER FUNCTION, b VALUE:
The b value of 0.35 was used in RULSE. This value is associated with permanent grasses on medium and
coarse textured soils.
CANOPY FALL HEIGHT:
Average canopy fall height used in RUSLE was 0.3 ft. Fall height is the average distance a raindrop falls
to the soil surface after being intercepted by canopy. Live plant material at or near the soil surface is
generally assumed to be ground cover in the Time Variant option of RUSLE. Therefore the fall height for
grasses was increased from 0.1 for the Time Variant option to 0.3 for these calculations using the Time
Invariant option to reflect pasture canopy cover.

ESTIMATING THE COVER AND MANAGEMENT C FACTOR FOR UNDISTURBED
AREAS OF PERMANENT PASTURE, WILDLIFE, WOODLAND, AND IDLELAND
Factor C of the equation combines three distinct types of effects of cover and management on detachment
and transport capacitities of rainfall and runoff.
Leaves and branches that do not directly contact the soil are effective only as canopy cover. Canopies
have little influence on the amount and velocity of runoff, but they do intercept falling raindrops.
Waterdrops falling from the canopy may regain an appreciable velocity, but not the same velocity of freefalling raindrops. The canopy reduces rainfall erosiveness by reducing its impact energy at the soil
surface. The amount of reduction depends on the height and density of the canopy.
For partial canopies, “percent cover” is defined as the percentage of the total surface area that could not
be hit by vertically falling raindrops because of the canopy. Thus the effective EI for a given area is
lineally proportional to the percentage of the ground that is not covered by the canopy.
A mulch at the soil surface is much more effective than an equivalent percentage of raised canopy. Since
the intercepted raindrops have no remaining fall-height to the ground, their impact on the soil surface is
essentially eliminated. Of probably even greater importance, a mulch that makes a good contact with the
ground also reduces the velocity of runoff. The reduction in its velocity greatly reduces the potential of
the runoff to detach and transport soil material.
If the cover includes both raised canopy and surface mulch and if the canopy and mulch overlap, both
cannot be fully credited. This is because the impact energy of the raindrops that strike the mulch is
dissipated at that point regardless of whether or not the fall velocity of the drop had been previously
reduced by canopy interception. The mulch factor is taken at full value and the canopy factor is reduced
to apply only to the percentage of the surface that is not covered by mulch.
The residual effects of roots and subsurface stems is quite noticeable when considereing the amount of
soil loss that can be expected from a given area. When plant composition and density of the pasture
reduces, the residual effects of the plants diminish proportionately. The residual effects of weeds are less
than grass. The cross-sectional areas of trees or stalky weeds that control the ground only at their base are
insignificant relative to the total land area and are not included.

Description
In this condition, the grass is dense and runoff is very slow,
about the slowest under any vegetative condition.
In this condition, the hay is a mixture of grass and legume just
before cutting. The meadow is a good stand of grass that is
nearing the end of the first year.
Ground cover for this condition is about 75 to 95%. Roughness
would be like that left by a high clearance moldboard plow on a
heavy textured soil. Roughness depressions would have the
appearance of being 7 inches deep and deeper. Vegetative
hydraulic roughness would be like that from a good legume crop,
such as lespedeza, that has not been mowed.
The ground cover for this condition is about 40 to 65%. This
roughness would be like that left by a moldboard plow in a
medium textured soil. Depressions would have the appearance of
being about 4 to 6 inches deep. Vegetative hydraulic roughness
would be much like that produced by winter small grain at full
maturity.
Ground cover is between 10 and 35% and the surface
roughness is like that left by the first pass of a tandem disk over
a medium texture soil that has been moldboard plowed. This
roughness could also be much like that left after a chisel plow
through a medium textured soil at optimum moisture conditions
for tillage. Roughness depressions would have the appearance
of being on the order of 2 to 3 inches deep. In terms of hydraulic
roughness produced by vegetation, this condition is much like
that produced by spring small grain at about three fourths
maturity.
This condition is like the condition typically found in row cropped
fields after the field has been planted and exposed to a
moderately intense rainfall. Ground cover is less than about 5%
and the roughness is characteristic of a good seedbed for corn
or soybeans. The surface is rougher than that of a finely
pulverized seedbed for seeding vegetables or grass.
This condition is essentially bare with a cover of 5% or less. The
soil has not had a crop grown on it in the last 6 months or more.
Much of the residual effects of previous cropping have
disappeared. The surface is smooth, much like the surface
exposed to several intense rainfalls. This condition may be
found in fallowed and vegetable fields, or in newly sown lawns
and hay fields.

Example:
Step 1. The Pc Subfactor determined using Table 10 was 0.72. The slope length “L” is 300 feet. The
Critical Slope Length is 200. Therefore we need to determine the “Effective Pc Subfactor because the
field slope length exceeds the critical slope length by 100 feet.
Step 2. Divide Actual Slope Length by the Critical Slope Length (300 / 200 = 1.5) to determine the Ratio
of Actual Slope Length to Critical Slope Length (1.5)
Step 3. On Table 13 (above) locate the column 0.7 (Pc Subfactor Determined from Table 10) it is closest
to the 0.72. Go down the left column until you find the ratio of 1.5 (or closest ratio); move across until the
1.5 row intersects the 0.7 column. The new “Effective Pc = 0.84.
This indicates that since the field slope length exceeds the critical slope length the contour or strip
cropping is less effective (0.72 vs. 0.84) and will provide less erosion control.

USING THE EQUATION - A = RK(LS)CP
The soil conservationist can use the RUSLE in helping plan land use, and necessary conservation
practices.
From the soil map, determine the soil type. If the soil is a Blount loam, the erodibility factor (K) is 0.43.
The distance from where the water originated, usually the top of the hill to a waterway or where
sedimentation begins, is the slope length. This may be a distance of 200 feet, and the average slope may
be 6 percent. The farmer is growing continuous corn and plows the field with a moldboard plow every
spring up and down the slope just prior to corn planting. The average corn yield for this field is 125
bu/ac/yr. It is in Clinton County and the "C" factor zone is 102B.
We can determine soil loss as follows: The rainfall factor (R) is 90 and the soil erodibility factor (K) is
0.43, the slope is 6% and 200 feet long, giving an LS factor of 1.05 and Blount has a T of 5. The
Technical Guide, Table 6 - 102B for the Lower Peninsula, gives continuous corn grain, 125 bu/ac/yr
yield, plowed in the spring, residues left, a C factor of .18. These figures give us a soil loss of 7.3 tons
per acre per year. A = (90)(.43)(1.05)(.18)(1.0) = 7.3
This is too much soil loss to maintain a permanent productive agriculture program and it might cause
sedimentation damage downstream. What are the alternatives? The farmer can grow other crops in the
rotation, he can shorten the slope by terracing or he can manage his crop residue by leaving it on the
surface with conservation tillage. Sometimes it is necessary to do all three.
If the farmer substitutes chiselling for clean plowing and leaves 1,000 pounds (20%) of corn residue on
the soil surface after planting, the C factor is reduced from .18 to .14 and the predicted soil loss is 5.4 tons
per acre. This is still above the tolerable 5 tons per acre soil loss for Blount. A =
(90)(.43)(1.05)(.14)(1.0) = 5.7 T/Ac./Yr.
If the farmer uses no-till leaving 6,500 pounds (90%) of corn residue on the soil surface after planting, the
C factor is 0.01 and the predicted soil loss is 0.4 tons per acre, an acceptable amount. A =
(90)(.43)(1.05)(.01)(1.0) = 0.4 T/Ac./Yr.
The equation is used to predict the average annual soil loss that might be expected over a period of years.
There will be year to year fluctuations. In some years the soil loss may exceed T depending on the
percent cover after planting and the crop being grown.
Thus, the equation is used as a guide when assisting in the development of conservation plans and
application of practices on the land.
Regardless of the factors used to predict soil loss, the Revised Universal Soil Loss Equation can be used
to:
Help develop safe conservation crop rotations.
Determine needed conservation practices.
Sell better tillage systems and use of crop residue management.

WATER QUALITY AND SEDIMENT YIELD
Sediment yield should not be confused with erosion; the terms are not interchangeable. Sediment yield is
the amount of eroded soil that is delivered to a point in the watershed that is remote from the origin of the
detached soil particles. In a watershed, sediment yield includes erosion from: slopes, channels, and mass
wasting minus the sediment that is deposited after it is eroded but before it reaches the point of interest.
RUSLE does not estimate sediment yield.
Computed soil loss (A) for large areas is not sediment yield, and is not directly related to water quality.
Overland sediment transport is a complex process of transport and deposition. The USLE estimates the
transport component and specifically excludes the deposition component. For example, only 5 percent of
computed soil loss may appear as sediment in a drainage area of 500 square miles. The remaining 95
percent is redistributed and deposited on uplands or flood plains and is not a net soil loss.
Gross erosion must be accounted for when the concern is total sediment yield. Sources of sediment, in
addition to sheet and rill erosion (i.e. gully, stream, ditch, etc.), must be included in order to arrive at
gross erosion. Total sediment yield equals gross erosion times sediment delivery ratio.
The capacity of overland and channel flow to transport sediment is influenced heavily by land forms and
channel characteristics. An inverse relationship between drainage area size and sediment delivery ratio
has been indicated through analysis of erosion and sediment data. This relationship is explained by the
general tendency for the greater proportion of depositional areas to be located in the lower parts of
drainage areas. The table below can be used to select sediment delivery ratios for making rough estimates
of sediment yield.

Soil erosion x acres x sediment delivery factor = sediment yield.
The estimated soil erosion in tons per acre, times the acres of the eroded area, times the appropriate
sediment delivery factor, equals the sediment yield.
