Relative water attenuation within canopy

u_c.Rd

#' @description A short description...

Usage

u_c(
  U0,
  macro_state = c(biomass, hm),
  site_params,
  spec_params,
  constants = c(s = 0.0045, gam = 1.13, a2 = 0.2^2, Cb = 0.0025)
)

Arguments

U0

incoming incident water velocity (m/s)

macro_state

vector of named numbers. Must include:

  • biomass, macroalgae wet weight (g)

  • hm, algae height (m)

site_params

vector of named numbers. Must include:

  • hz, total water depth (m)

  • hc, vertical water column occupied by the canopy (m)

  • d_top, depth of the top of the canopy beneath the water surface (m)

spec_params

vector of named numbers. Must include:

  • SA_WW, conversion of wet weight to surface area

constants

vector of named numbers defining extra constants for the attenuation submodel. Must include:

  • s = 0.0045

  • gam = 1.13

  • a2 = 0.2^2

  • Cb = 0.0025

Value

the relative water attenuation coefficient (u_c)
