summary.VFS: Summarize the result of VFS

In VFS: Vegetated Filter Strip and Erosion Model

Description

Summary method for VFS objects.

Usage

	## S3 method for class 'VFS'
summary(object, ...)

Arguments

object	A VFS object produced by VFS().
...	Other arguments to summary

Details

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.

Value

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.
