Detailed Description

Calculates ETpot after Oudin et al 2005.

https://doi.org/10.1016/j.jhydrol.2004.08.026 This ETpot formula is a generalization of two older approaches by introducing parameters to shape the dependency of ETpot from temperature and extraterrestrial radiation

\( \lambda ET_{pot} = R_{a} \cdot \frac{T_{a} + K_2}{K_1}\)

Oudin et al (2005) found an optimum for \(K_1=100, K_2=5\). The origin of this formula lays in Jensen & Haise (1963) with \(K_1=40, K_2=0\) and McGuiness-Bordne (1972) with \(K_1=68, K_2=5\).

Public Member Functions

real conc (cmf::math::Time t, const cmf::water::solute &_Solute)
 Returns the concentration of the flux.
 
flux_node::ptr get_target (const flux_node &inquirer)
 Returns the other end of a connection than the asking end.
 
flux_node::ptr get_target (int index) const
 With index 0, the left node is returned, with index 1 the right node of the connection.
 
real get_tracer_filter ()
 A value ranging from 0 to 1 to filter tracers out of the water flux.
 
real get_tracer_filter (solute S)
 A value ranging from 0 to 1 to filter tracers out of the water flux.
 
bool kill_me ()
 Deregisters this connection from its nodes. Returns true if only one reference is left.
 
flux_node::ptr left_node () const
 Returns the left node of this connection.
 
real q (const flux_node &inquirer, cmf::math::Time t)
 Returns the current flux through a connection. Negative signs mean out of the inquirer, positive are inflows to the inquirer.
 
void refresh (cmf::math::Time t)
 Performes a new calculation of the flux.
 
flux_node::ptr right_node () const
 returns the right node of this connection
 
void set_tracer_filter (real value)
 A value ranging from 0 to 1 to filter tracers out of the water flux.
 

Static Public Member Functions

static void use_for_cell (cmf::upslope::Cell &cell)
 Connects all soil layers with the transpiration node of the cell.
 

Public Attributes

 A string describing the type of the connection.
 

Member Function Documentation

◆ conc()

real conc ( cmf::math::Time t,
const cmf::water::solute & _Solute )
inherited

Returns the concentration of the flux.


If not overridden, it returns the concentration of the source of the flux (direction depending)

◆ get_tracer_filter()

real get_tracer_filter ( )
inherited

A value ranging from 0 to 1 to filter tracers out of the water flux.

1.0 is no filter and 0.0 means no solute is crossing this connection

◆ set_tracer_filter()

void set_tracer_filter ( real value)
inherited

A value ranging from 0 to 1 to filter tracers out of the water flux.

1.0 is no filter and 0.0 means no solute is crossing this connection
