nsink_calc_off_network_removal: Calculates off network waterbody and stream nitrogen removal

In USEPA/nsink: Flow path nitrogen removal estimation

Calculates off network waterbody and stream nitrogen removal

Description

Calculates off network waterbody and stream nitrogen removal

Usage

nsink_calc_off_network_removal(
  input_data,
  off_network_lakes,
  off_network_streams,
  off_network_canalsditches
)

Arguments

input_data	A named list with "streams", "lakes", "network_removal", "tot", and "raster_template".
off_network_lakes	Optional argument to set removal for waterbodies that are not part of the NHDPlus hydrologic network. Default value is to use the 75th percentile of removal from other lakes in the HUC. If another value is desired provide a single numeric ranging from 0 to 1.
off_network_streams	Optional argument to set removal for streams that are not part of the NHDPlus hydrologic network. Default value is to use the median removal from first order streams in the HUC. If another value is desired provide a single numeric ranging from 0 to 1.
off_network_canalsditches	Optional argument to set removal for canals and ditches that are not part of the NHDPlus hydrologic network. Default value is to use the 25th percentile of removal from third order streams in the HUC. If another value is desired provide a single numeric ranging from 0 to 1.

Value

Raster and vectors of off network nitrogen removal
