Summary method for VFS objects.
## S3 method for class 'VFS' summary(object, ...)
object |
A VFS object produced by VFS(). |
... |
Other arguments to summary |
Calculates means and standard deviations for annual removal efficiencies. If model type is erosion-only (no vegetated filter strip simulated), then only the relevant variables describing erosion from the field are returned.
ALR |
Annual load reduction. |
ALRsd |
SD of annual load reduction. |
ALR1000 |
Load reduction across full timespan. |
ALR1000sd |
SD of load reduction across full timespan. |
APEA |
Annual per-event average reduction. |
APEAsd |
SD of annual per-event average reduction. |
SedIn |
Sediment entering the vegetated filter strip per year. |
SedInsd |
SD of sediment entering the vegetated filter strip per year. |
SedLoss |
Sediment lost per year. |
SedLosssd |
SD of sediment lost per year. |
TLR |
Total load reduction. |
RunoffDays |
Days per year with runoff. |
RunoffDayssd |
SD of days per year with runoff. |
Days |
Total number of days. |
