"WebMar 3, 2005 · There are several extensions to the Theis solution including the Hantush and Jacob solution for a leaky aquifer. This model assumes that the aquifer is bounded on top by a low permeability aquitard beneath a more permeable aquifer containing a standing water table; for example see Hunt ( 2003 ) for more details and for other models.
