Anisotropy of permeability in sandy residual soils developed on the sediments of the Itararé group

Abstract

The objective of this study was to identify the occurrence of anisotropy in residual soil from the Itararé Group and that is present in the Campinas-SP region. Its characterization was carried out through geotechnical tests and the determination of its hydraulic conductivity in the horizontal and vertical directions. It is sand-silty soil with anisotropy of 10, as the average hydraulic conductivity determined in the survey was 5.7 x 10-4 cm / s and in the vertical direction was 5.7 x 10-5 cm /s. A panel was also set up to carry out the permeability tests that will be available for use at the Faculty of Agricultural Engineering (FEAGRI) of UNICAMP.
