get_dam_passage: Get dam-specific survival rates

In danStich/penPass: R package for Atlantic salmon PenPass model

Get dam-specific survival rates

Description

Get correlated dam-specific downstream survival rates for smolts at each dam from built-in 'downstream_' datasets or default values based on triangular distributions or fixed rates used in Stevens et al. (2019). Values based on Amaral et al. (2012) and sampled following Nieland et al. (2013, 2015) and Nieland and Sheehan (2020), sampled using 'EnvStats::rtri()', or fixed to 1 for other dams based on Stevens et al. (2019).

Usage

get_dam_passage(year, flow)

Arguments

year	Year of simulation
flow	A numeric vector of length 21 containing flow values (cfs) corresponding to dams in rows in flow_ratios and the 'upstream' argument of run_one_year.

Value

Numeric vector with dam passage rates
