- thiem(rad, r_ref, transmissivity, rate=- 0.0001, h_ref=0.0)[source]¶
The Thiem solution.
The Thiem solution for steady-state flow under a pumping condition in a confined and homogeneous aquifer. This solution was presented in [Thiem1906].
- Parameters
rad (
numpy.ndarray
) – Array with all radii where the function should be evaluated.r_ref (
float
) – Reference radius with known head (see h_ref).transmissivity (
float
) – Transmissivity of the aquifer.rate (
float
, optional) – Pumpingrate at the well. Default: -1e-4h_ref (
float
, optional) – Reference head at the reference-radius r_ref. Default:0.0
- Returns
head – Array with all heads at the given radii.
- Return type

Notes
The parameters
rad
,r_ref
andtransmissivity
will be checked for positivity. If you want to use cartesian coordiantes, just use the formular = sqrt(x**2 + y**2)
