Function initCochardNetworks initializes hydraulic networks for all plant cohorts in x Function semi_implicit_integration updates water potentials and cavitation across the hydraulic network

initCochardNetworks(x)

semi_implicit_integration(
  network,
  dt,
  opt,
  cavitationRefillStem = "annual",
  cavitationRefillLeaves = "total"
)

Arguments

x

An object of class spwbInput or growthInput created using transpirationMode = "Cochard".

network

A hydraulic network element of the list returned by initCochardNetworks

dt

Smallest time step (seconds)

opt

Option flag vector

cavitationRefillStem, cavitationRefillLeaves

A string indicating how refilling of embolized conduits is done:

  • "none" - no refilling.

  • "annual" - every first day of the year.

  • "rate" - following a rate of new sapwood formation.

  • "total" - instantaneous complete refilling.

Value

Function initCochardNetworks returns a vector of length equal to the number of cohorts. Each element is a list with Sureau-ECOS parameters. Function semi_implicit_integration does not return anything, but modifies input parameter network.
