linesink: Create a strength-specified line-sink analytic element
Description
linesink() creates a line-sink analytic element with constant specified strength.
Usage
linesink(x0, y0, x1, y1, sigma, width = 0, ...)
Value
Strength-specified line-sink analytic element which is an object of class linesink and inherits from element.
Arguments
x0
numeric, starting x location of line-sink.
y0
numeric, starting y location of line-sink.
x1
numeric, ending x location of line-sink.
y1
numeric, ending y location of line-sink.
sigma
numeric, specific strength of the line-sink, i.e. discharge per unit length of line-sink. Positive is out of aquifer.
width
numeric, width of the line-sink. Only used in tracelines() to determine if a particle has reached the line.
Defaults to zero (infinitesimally narrow line).
