Our next PhDTalks Seminar will be held on tuesday 27^th february in Fassò Room (Building 4A), from 5:15 pm to 6:30 pm CET. 

PhDTalks is a series of seminars and discussions between PhD students. The events are aimed at providing a place to network and get in contact with many of the projects developed in our department. 

Speaker Lorenzo Panzeri will talk about “A Mixed-dimensional solver for the geoelectrical analysis of highly resistive liners in landfills”. 

At the end of each event a small refreshment funded by the department will be available.

Abstract

The analysis of the condition of the liner beneath municipal waste landfills is of considerable importance to prevent the spread of pollutants into the underlying layers down to the groundwater zone. Being at depths of several tens of metres in an uncertain location, it is crucial to find an effective method for its identification. Direct current (DC) methods, in particular ERT (Electric Resistivity Tomography), exploit the conductive and resistive properties of the materials, permitting the identification of both the location of the highly resistive HDPE (High density polyethylene) membrane and the possible diffusion area of the pollutant, which, due to its high salt content, is highly conductive.  A new mixed-dimensional Finite volume numerical model is developing for solving the forward and inverse problems in DC resistivity surveys.
