run_downstream_passage: Run downstream passage routine

In danStich/dia: R package for Atlantic salmon Dam Impact Analysis (DIA) model

Run downstream passage routine

Description

Run the downstream passage routine for Atlantic salmon Dam Impact Analysis (DIA) model v67. Default usage is to inherit all arguments from run_dia or run_one_gen. **Not intended to be called directly.**

Usage

run_downstream_passage(
  stocked_smolts,
  wild_smolts,
  downstream_passage,
  in_river_s,
  p_stillwater,
  mattaceunk_impoundment_mortality,
  n_dams,
  indirect_latent_mortality,
  p_female
)

Arguments

stocked_smolts	Number of hatchery smolts stocked by PU.
wild_smolts	Number of wild-reared smolts.
downstream_passage	Numeric vector with length = 15 corresponding to dam passage efficiencies at each of 15 dams in the watershed that are used to delineate PUs.
in_river_s	In-river survival per kilometer for downstream migrating smolts. The default 'NA' value simulates from cumulative distribution function using values in in_river_m.
p_stillwater	Probability that fish use the Stillwater Branch for downstream migration.
mattaceunk_impoundment_mortality	Mortality incurred by Atlantic salmon smolts during migration through the Mattaceunk (Weldon) Dam impoundment.
n_dams	A dataframe with structure identical to the built-in link{n_dams} data set.
indirect_latent_mortality	Indirect, latent mortality incurred by Atlantic salmon smolts at each dam passed.
p_female	Proportion of females in population.

Value

A named list with four elements including total number of hatchery and wild smolts exiting the Penobscot River (elements 1 & 2) as well as the proportion of wild and hatchery smolts exiting the river from each natal PU.
