ABSTRACT

Abstract: An electrical image has been delineated at a site located in Jahangirnagar University, Savar, Dhaka, Bangladesh to deduce a shallow subsurface heterogeneity in terms of geophysical and geotechnical properties. The depth of investigation covers up to 12m includes the Madhupur Clay Formation of Pleistocene age and upper part of Dupi Tila Formation of Pliocene age. The Madhupur Clay Formation extends up to 7.5m with a wide range in resistivity values (5-45 Ωm) whereas the sand rich Dupi Tila Formation shows relatively higher resistivity (>190 Ωm). The resistivity values are significantly controlled by moisture content and grain size distribution.
