Aquifer tests are commonly used to determine the hydrodynamic characteristics and boundary limits of stratified confined aquifers. However, the interpretation of the resulting data is made based on very simplistic assumptions lacking real-world validation. Heterogeneous and anisotropic layered aquifers are frequently treated using homogeneous anisotropic equivalent models whose neither spatial nor temporal validity have been assessed. This paper proposes a new approach to allow for a more reliable and appropriate application in such conditions, thus, overcoming the shortcomings of these models.
