Semi-infinite aquifer

 

Assumptions:

aquifer is confined, isotropic with one lateral boundary;

the boundary is straight of infinite length;

drawdown can be estimated at any distance from the pumping well.

 

Two types of boundary conditions are taken into account:

1) recharge boundary (Dirichlet)

2) no-flow boundary (Neumann).
