Relative capillary conductivity

Relative capillary conductivity based on Mualem's conductivity model for unimodal or bimodal van Genuchten-Mualem.

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

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

par.shp

named parameter in list or vector

suc.negativ

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

modality

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

Details

additional for bimodal (modality == 'bi') w2 [-]: weigthing between pore space distribution alfa2 [1/L]: van Genuchten parameter alfa for second pore space distribution n2 [-]: van Genuchten parameter n for second pore space distribution
