Loss through fragmentation
loss.RdThe macroalgae fragmentation rate (\(D\)) is calculated as: $$D = D_{ve} \times U_0 + D_{tu} + D_{m}$$ where \(D_{ve}\) is the linear coefficient of loss with laminar velocity (\(U_0\)), \(D_{tu}\) is the loss rate at the specified level of turbulence (static, low, medium, or high), and \(D_{m}\) is the base loss rate.
Arguments
- U0
incoming incident water velocity (m/s)
- turbulence
optional level of turbulence. Options are "none"/"static", "low", "medium"/"mid", and "high".
- spec_params
a vector of named numbers. All default to 0 if not supplied. Can include:
D_m, a constant (base) loss rateD_ve, the linear coefficient of loss with laminar velocityD_st, the loss rate in static water (turbulence = 0, "none" or "static")D_lo, the loss rate in turbulent water (turbulence = 1 or "low")D_mi, the loss rate in turbulent water (turbulence = 2 or "medium")D_hi, the loss rate in turbulent water (turbulence = 3 or "high")
