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.
