ptf.cW: Title Corrected Weynants et al. (2009) Pedotransfer Function

In spsh: Estimation and Prediction of Parameters of Various Soil Hydraulic Property Models

Description

Title Corrected Weynants et al. (2009) Pedotransfer Function

Usage

ptf.cW(CLAY, SAND, BD, OC)

Arguments

CLAY	A vector of n elements with soil clay content (particle diameters <= 2 x 10e-6 m), in percent [0, 100]).
SAND	A vector of n elements with soil sand content (particle diameters < 2 mm and > 50 x 10e-6 m), in percent [0, 100]).
BD	A vector of n elements with soil bulk density (g/cm3).
OC	A vector of n elements with soil organic carbon content, in percent [0, 100].

Value

Pedotransfer function returns the van Genuchten - Mualem model parameters given CLAY, SAND, BD, and OC. The correction of the original paper presented by \insertCiteWeynants.2009spsh, were made by \insertCiteWeihermuller.2017spsh, which is implemented.

Note

The PTF is not suitable for predicting the hydraulic conductivity curve at pressured heads > -6 cm \insertCiteWeynants.2009spsh.
