Output Details Table
The Output Details report contains all of the erosion, weather, and surface information
available by period, by rotation year, and for the entire simulation run.
The columns of the Output Details report have the following information.
- Date
- - This column contains the start and end dates (day/month/rotation year) of the reporting period.
- Operation
- - This column contains the management operation which occurred on the specified date.
- Wind Erosion
- Average Total Gross Soil Loss
- - The Average Total Gross Soil Loss is the average erosion within the field, averaged across the field as
well as averaged over the number of simulation years in each rotation year (kg/m2 or tons/acre).
- Net Soil Loss from Field
- Average Total
- - The average total net loss from the field(kg/m2 or tons/acre).
- Average Creep/Sal.
- - This column contains the total creep plus saltation net loss for the period,
averaged across the field grid areas, as well as averaged over the number of simulation
years in each year of the crop rotation (kg/m2 or tons/acre).
- Average Susp.
- - This column contains the total suspension net loss for the period, averaged
across the field grid areas as well as averaged over the number of simulation

material passing each field boundary (kg/m or tons/1000 ft) in the
direction indicated
.

each field boundary (kg/m or tons/1000 ft) in the direction indicated
.

- Within Field Wind Erosion Activity
- The information in this section is useful in determining how much of the field is actively
eroding and how much is not, which may impact what control measures, if any should be
applied and where. This information is also useful in understanding how much of the field
is actively eroding and thus may be causing plant or soil damage or how much is subject to
burial. Finally, this information is useful in understanding how much of the field is
contributing to overall (net) field loss.

had saltation emission (kg/m2 or tons/acre).

- - These columns display both the area (acres or hectares) and fraction of that
area of the field that had saltation emission.

- Soil Deposition
- - This column displays the amount of soil deposited in that area of the
field where deposition is the primary activity (kg/m2 or tons/acre).
- Field Area
- - These columns display both the area (acres or hectares) and fraction of that
area of the field that had deposition.
- High Flux Region
- Field Area
- - These columns display both the area (acres or hectares) and fraction of that
area of the field which was near transport capacity.
- Sheltered Region
- Field Area
- - These columns display both the area (acres or hectares) and fraction of that
area of the field that had no saltation or suspension material being emitted.
Sheltered areas are typically those immediately downwind of barriers.

greater than 8 m/s, averaged over the simulation years in each year of the crop

the period end, averaged over the simulation years for the period listed (fraction).
- Effective Standing Silhouette
- - Effective standing silhouette is the standing silhouette area index of live
plants expressed on a fraction basis. If the plants are planted in the furrow as opposed
to the ridge top, the index is adjusted (down) to have less of an effect on the wind.
These are values at the period end averaged over the simulation years in each rotation year.
- Above Ground Mass
- - This column contains the total live crop biomass, above ground, at the period end,
averaged over the simulation years for the period listed (kg/m2 or lbs/acre).
- Crop Residue (Dead)
- Flat Cover
- - This column contains the amount of flat dead cover on the soil
surface, expressed as a fraction. These are values at the period end
averaged over the simulation years in each rotation year (fraction).
- Effective Standing Silhouette
- - Effective standing silhouette is the standing silhouette area index of dead
plants expressed on a fraction basis. If the plants are planted in the furrow as
opposed to the ridge top, the index is adjusted (down) to have less of an effect on the
wind. These are values at the period end averaged over the simulation years in each
rotation year.
- Flat Mass
- - This column contains the amount of flat dead biomass on the soil surface.
These are values at the period end averaged over the simulation years in each
rotation year (kg/m2 or lbs/acre).
- Standing Mass
- - This column contains the amount of standing dead biomass on the
soil surface. These are values at the period end averaged over the
simulation years in each rotation year (kg/m2 or lbs/acre).
- Live and Dead Biomass

(flat cover) biomass on the soil surface expresses on a fraction basis. These are
values at the period end averaged over the simulation years in each rotation year (fraction).
- Standing Silhouette
- - Effective standing silhouette is the standing silhouette area index of live plus
dead plants. If the plants are planted in the furrow as opposed to the ridge top, the

- Average Soil Surface Conditions on Date
- Oriented Roughness
- Ridge Orientation
- - This column contains orientation of the ridges with zero degrees

random roughness. This is the value at the period end averaged over
the simulation years in each rotation year (mm or inches).
- Aggregation
- Aggregates > 0.84 mm
- - This column lists the fraction of aggregates greater than 0.84 mm.
Aggregates > 0.84 mm are generally considered to be non-erodible. This is the
value at the period end averaged over the simulation years in each rotation year.
- Aggregate Stability
- - This column lists aggregate stability which is the log of crushing energy of
dry soil aggregates (ln(J/kg)) and is related to abrasion resistance. This is the
value at the period end averaged over the simulation years in each rotation year.
- Crust Cover
- - This column lists the fraction of the soil surface that is crusted. This is the
value at the period end averaged over the simulation years in each rotation year.
- The rows in the Output Details table vary
depending on the number of cropping years in the rotation and the number of management
operations in each year of the rotation.
- Each year of the rotation has output displayed for the two week periods as well as for each
management operation date. This output allows the user to view the erosion and other output
for each year of the rotation. At the end of each year in the rotation is a row which contains
the average annual value for that rotation year.
- The last row in the output form contains the average annual values for the complete crop
rotation.
