A method for evaluation of permeability coefficients in aquifers

Abstract

The present work is an attempt to obtain approximate values of aquifer permeability coefficients whose structure often exhibit bedding. The inethod consist in its essence, through some restrictive conditions, in the establishment of a linear equation system. For this purpose it is utilized known data of tubular wells within a limited area under the hypothesis that each aquifer strata behave as an individual free water table: An example the applicability, it is presented using data draw out of three tubuTar wells from lhe town of Catanduva. Nevertheless, the weIls have an imaginary sedimentary strata due to a lack of an adequated geological profiles description. They does not foIlow the restrictive conditions established on such method, because the water contributions from underlying fractured rocks, should have come probably, from Botucatu Formation
