Runoff reduction percentages as used in Exposit

A table of the runoff reduction percentages used in Exposit 3 for different vegetated buffer widths

perc_runoff_reduction_exposit

Format

A named list of data frames with reduction percentage values for the dissolved fraction and the fraction bound to eroding particles, with vegetated buffer widths as row names. The names of the list items are the Exposit versions from which the values were taken.

dissolved

The reduction percentage for the dissolved phase

bound

The reduction percentage for the particulate phase

Agroscope version 3.01a with additional runoff factors for 3 m and 6 m buffer zones received from Muris Korkaric (not published). The variant 3.01a2 was introduced for consistency with previous calculations performed by Agroscope for a 3 m buffer zone.
