vs2dh.ConfigureGenuchten: Configure Genuchten flow parameters

In KWB-R/kwb.vs2dh: Interface to VS2DH

Description

Configure Genuchten flow parameters

Usage

vs2dh.ConfigureGenuchten(ratioKzKh = 1, satKh = 750, ss = 0,
  porosity = 0.39, alpha = 2.3, rmc = 0.05, beta = 5.8)

Arguments

ratioKzKh	Ratio of hydraulic conductivity in the z-coordinate direction to that in the x-coordinate direction (Default:1)
satKh	Saturated hydraulic conductivity (K) at 20 C in the x-coordinate direction for class ITEX, L/T. (Default: 750 m/d)
ss	Specific storage (Ss), L^-1. (Default: 0)
porosity	Porosity (f), (Default: 0.39)
alpha	van Genuchten alpha. NOTE: alpha is as defined by van Genuchten (1980) and is the negative reciprocal of alpha' used in earlier versions (prior to version 3.0) of VS2DT, L., (Default: 2.3/m)
rmc	Residual moisture content, (Default: 0.05)
beta	van Genuchten parameter, beta' in Healy (1990) and Lappala and others (1987), (Default:5.8)

Value

Genuchten flow parameters
