Detailed Description

A simple kinemtic wave model for subsurface flux.

\[ q = \frac{\Delta z_{surface}}{d} K(\theta)_{source} A_{cross} \]

Public Member Functions
	DarcyKinematic (cmf::upslope::SoilLayer::ptr left, cmf::water::flux_node::ptr right, real FlowWidth, real Distance=0)
	Creates the connection.

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.

Public Attributes
const std::string	type
	A string describing the type of the connection.

Constructor & Destructor Documentation

Creates the connection.

Parameters

left	Left node of the connection (needs to be soil water storage)
right	Right node of the connection (can be any node)
FlowWidth	the width of the connection - is multiplied by layer thickness to get the interface area
Distance	the length of the connection. If 0, the distance is calculated from the position of the nodes

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)

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

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
