Relative water attenuation beneath canopy

u_b.Rd

Relative water attenuation beneath canopy

Usage

u_b(
  U0,
  macro_state,
  SA_WW = 0.5 * (0.0306/2),
  site_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)

constants

vector of named numbers defining extra constants for the attenuation submodel. Must include all constants, which have the following default values:

  • s = 0.0045

  • gam = 1.13

  • a2 = 0.2^2

  • Cb = 0.0025

Value

a scalar of relative water attenuation beneath canopy
