pFpara_ptf_Wosten1999 {OBIC}

Estimate water retention curve parameters based on Wosten 1999

Description

This function estimates water retention curve parameters using Pedo transfer function of Wosten (1999) based on HYPRES

Usage

pFpara_ptf_Wosten1999(Pklei, Psilt, Psom, Bovengrond)

Arguments

Pklei

(numeric) The clay content of the soil (%) within soil mineral part. Pklei > 0

Psilt

(numeric) The silt content of the soil (%) within soil mineral part. Psilt > 0

Psom

(numeric) The organic matter content of the soil (%). Psom > 0

Bovengrond

(boolean) whether topsoil (1) or not (0)

Value

a table with the following columns:

Dichtheid (numeric) soil bulk density (g/cm3) ThetaR (numeric) residual water content (cm3/cm3) ThetaS (numeric) saturated water content (cm3/cm3) alfa (numeric) related to the inverse of the air entry suction, alfa > 0 (1/cm) n (numeric) a measure of the pore-size distribution, n>1, dimensionless ksat (numeric) saturated hydraulic conductivity (cm/d)
