Resumen:
Traditional analytical solutions for the evaluation of pumping tests
under non-steady state conditions are applicable when the aquifer can be
simplified as constant horizontal strata of infinite extension and
homogeneous soil. Nevertheless, when such conditions are not
representative of the study area, analytical solutions present
considerable limitations. This paper discusses the application of 3D
numerical modeling as a powerful tool to evaluate complex pumping well
systems when it is mandatory to represent topography and variable
thickness stratigraphic conditions of the study area. Furthermore,
application of the analytical solutions is highlighted as a previous
analysis to characterize the hydraulic properties of the aquifer
(permeability, transmissivity and storage coefficient) and be took into
account in the numerical analyses. The practical application presented
in this paper utilized data from the northeastern part of the Valley of
Mexico, particularly from the area of the former Texcoco Lake, where the
construction of a new airport was planned. At the end some conclusions
are given about the design and analysis of pumping well systems.
