Point source in a bounded aquifer
Assumptions:
✓aquifer is confined, anisotropic on the vertical plane, bounded on the vertical or horizontal plane;
✓boundaries: two lateral or profile straight, parallel boundaries of infinite length;
✓drawdown in the aquifer can be calculated at any distance from the pumping well.
Four kinds of boundary conditions are considered: 1) two profile no-flow boundaries (Neumann); 2) two lateral recharge boundaries (Dirichlet); 3) two lateral no-flow boundaries (Neumann); 4) two lateral boundaries of different types (recharge and no-flow).
