Radial well aquifer benchmark (Water Module)

This testcase demonstrates a situation where a pipe drainage is located below ground and is pumping up ground water. A characteristic water water level curve will form over time. File:Drainage freatic benchmark.png

Formulas

$\phi (r)-\phi _{0}={\frac {Q_{0}}{2\pi \cdot kD}}\ln {\left({\frac {r}{R}}\right)}$

where:

$phi(0)$: stable water level at the considered edge

$phi(r)$: water level between the considered edge and the well

$phi(rw)$: water level in the well
