Bounded aquifer

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).
