Create an analytic element of a constant-discharge well

well() creates an analytic element of a well with constant discharge.

Usage

well(xw, yw, Q, rw = 0.3, ...)

Arguments

xw: numeric, x location of the well.
yw: numeric, y location of the well.
Q: numeric, volumetric discharge of the well (positive is out of aquifer).
rw: numeric, radius of well. Defaults to 0.3 length units.
...: ignored

Value

Analytic element of a well with constant discharge which is an object of class well and inherits from element.

Details

The inner annulus of a well element constitutes a singularity in the equations as the hydraulic head is undefined at a distance smaller than rw from the well center. If a state- or flow-variable is calculated within this annulus, its location is reset to its nearest location on the well screen.

The well is assumed to fully penetrate the saturated aquifer.
