Detailed Description

A WaterStressFunction based on the stored water volume of a layer.

If the layer contains more water than V1, ET is not limited (ET=ETpot). Below V1 ET goes linear to 0.0 at V0

Public Member Functions
	VolumeStress (real V1, real V0)
	Creates a new water stress function for water volume.
cmf::upslope::ET::VolumeStress *	copy () const
	Creates a new copy of this wetness.
virtual real	Tact (const cmf::upslope::SoilLayer *soillayer, real Tpot) const
	Calculates the water stress for a layer.

Public Attributes
real	V0
	Lower volume threshold in \(m^3\). If the layer contains less water than V0, ET=0.0.
real	V1
	Upper volume threshold in \(m^3\). If the layer contains more water than V1, ET=ETpot.

Constructor & Destructor Documentation

VolumeStress()

VolumeStress	(	real	V1,
		real	V0 )

Creates a new water stress function for water volume.

Parameters

V1	Water content in \(m^3\) without stress (ET=ETpot)
V0	Water content in \(m^3\) with full stress (ET=0.0)

Member Function Documentation

Tact()

virtual real Tact ( const cmf::upslope::SoilLayer * soillayer, real Tpot ) const

virtual

Calculates the water stress for a layer.

Parameters

soillayer	The cmf::upslope::SoilLayer this stress function belongs to
Tpot	Potential Transpiration in mm/day (for the full profile)

Returns

Actual flux from layer in m3/day

Implements RootUptakeStressFunction.
