Relative film conductivity

Relative film conductivity described by Peters (2013).

Usage
Kfilm(suc, par.shp, modality = "uni", suc.negativ = TRUE)
Arguments
suc

Suction/pressure heads. Negative if suc.negativ = TRUE

par.shp

named parameter in list or vector

modality

pore size distribution ('uni' or 'bi')

suc.negativ

set TRUE if suction/pressure heads are negative and FALSE if positive

Details

additional for bimodal (modality == 'bi'): alfa2 [1/L]: van Genuchten parameter alfa for second pore space distribution n2 [-]: van Genuchten parameter n for second pore space distribution
