get_prop_crh_fhd {stochLAB} | R Documentation |
Calculate the total proportion of bird flights at collision risk based on a flight height distribution
Description
Calculate the expected proportion of bird flights at collision risk
height (i.e. at rotor height, between bottom and top of the rotor) based on the
bird's flight height distribution (Q'_{2R}
).
Usage
get_prop_crh_fhd(d_y)
Arguments
d_y |
Numeric vector with the proportion of birds at height bands across the rotor disc |
Value
The total proportion of birds at collision risk height derived from a flight height distribution
Examples
gen_fhd_dat <- Johnston_Flight_heights_SOSS %>%
dplyr::filter(variable=="Gannet.est") %>%
dplyr::select(height,prop)
gen_fhd <- gen_fhd_dat$prop
d_y <-
get_fhd_rotor(
hub_height = 150,
fhd = gen_fhd,
rotor_radius = 120,
tidal_offset = 2.5,
yinc = 0.05)
prop_chr_fhd <- get_prop_crh_fhd(d_y)
