confined, anisotropic on the vertical plane, of semiinfinite extent
vertical or lateral, straight, of infinite length;
the aquifer can be calculated at any distance from the pumping
Two kinds of
boundary conditions are considered: 1) lateral recharge boundary (Dirichlet); 2) lateral or profile no-flow boundary
Schematic cross-sections of semiinfinite aquifer.
a – profile boundary – top of the aquifer; b – profile boundary –
bottom of the aquifer; c – lateral recharge boundary; d – lateral
