Hantush and jacob
WebHantush, Madih Salih Graphical methods are outlined for determining the coefficients of transmissibility storage, and leakage of an effectively infinite leaky artesian aquifer. The procedure is based on the theory, developed by Hantush and Jacob, of the nonsteady flow toward a steadily discharging well from an infinite leaky aquifer. 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.

WebFeb 1, 2005 · Hantush and Jacob's model combined with EKF can optimally determine the parameters for leaky aquifers without considering the aquitard storage step-by-step in the identification process. Neuman and Witherspoon's model can also be employed in a similar manner in leaky aquifer with considering the aquitard storage.

In many cases, granular fill is placed below floor slabs (as specified in building codes such as HUD, 2006) and granular fill is several orders of magnitude more permeable than concrete.
