Detailed Description

Abstract base class for different types of retention curves.

This class, and its children uses wetness instead of volumetric water content. The wetness of a soil is defined as water content per void volume

Public Member Functions
virtual real	Diffusivity (real wetness) const
	Returns the Diffusivity of the soil.

virtual real	FillHeight (real lowerDepth, real Area, real Volume) const
	Returns the thickness of a soil column with a certain pore volume.

virtual real	K (real wetness) const
	Returns the conductivity in m/day at a certain depth and water content.

virtual real	MatricPotential (real wetness) const
	returns the wetness of the soil at given water content

virtual real	Porosity (real depth=0.0) const =0
	Returns the porosity at a certain depth.

virtual real	theta (real wetness) const
	returns the water content \(theta\) for a given wetness

virtual real	VoidVolume (real upperDepth, real lowerDepth, real Area) const
	Returns the void volume of a soil column.

virtual real	Wetness (real suction) const
	returns the wetness (volumetric water content per pore space) at a given suction pressure

virtual real	Wetness_eff (real wetness, real pF_r=4.2) const
	Returns the effective wetness, using a residual pF value.

real	Wetness_pF (real pF) const
	returns the volumetric water content at a given pF value

Member Function Documentation

virtual real Diffusivity ( real wetness ) const

virtual

Returns the Diffusivity of the soil.

Not implemented for all retention curves. Diffusivity is used by MACROlikeMacroMicroExchange

virtual real Wetness_eff	(	real	wetness,
		real	pF_r = 4.2 ) const

virtual

Returns the effective wetness, using a residual pF value.

\[w_{eff} = \frac{w_{act}-w\left(pF_r\right)}{1-w\left(pF_r\right)}\]
