fnc_AWC: Calculation of the plant available water content

In rhabel/modLWFB90: R-package for applying LWF-Brook90 directly from FVA-BW servers

Calculation of the plant available water content

Description

This function calculates the plant available water content (AWC, nutzbare Feldkapazitaet) from the Mualem-van Genuchten retention curve unsing fnc_MvG.swc. The function calculates the AWC per soil layer or for the whole depth at once. The gravel content is already taken into account.

Usage

fnc_AWC(data, nFK = F)

Arguments

data	is the list of soil properties calculated by fnc_get_soil
nFK	indicates whether the AWC is calculated for 1 m soil depth (nFK = T), returning a vector with one vector element for each list element. nFK = F returns the initial list with the additional columns: fc (vol. water content at 63 hPa), pwp (vol. water content at 15000 hPa) and AWC (AWC in mm per m^2 and depth of the soil layer)

Value

Returns either the expanded input list of soil properties or a vector containing the AWC for the whole soil depth with one vector element per input list element
