SUMMARY:PhDTalks | A Mixed-dimensional solver for the geoelectrical analysis of highly resistive liners in landfills
DESCRIPTION:Il prossimo appuntamento con la serie di incontri PhDTalks si terrà Martedì 27 febbraio nell’aula Fassò (Edificio 4A)\, dalle 17:15 alle 18:30 CET. \nPhDTalks è una serie di seminari e discussioni tra dottorandi. Gli eventi hanno lo scopo di fornire un luogo dove creare un network tra dottorandi ed entrare in contatto con i molteplici progetti sviluppati nel nostro dipartimento. \nLo speaker Lorenzo Panzeri condurrà un seminario dal titolo “A Mixed-dimensional solver for the geoelectrical analysis of highly resistive liners in landfills”.  \nAl termine dell’evento sarà disponibile un piccolo rinfresco finanziato dal dipartimento. \nSarà possibile seguire la conferenza anche online al seguente link. \nAbstract \nThe 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. \nDirect 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. \nSpeaker’s bio \nLorenzo is a PhD Candidate in Environmental and Infrastructure Engineering (37° cycle) at Politecnico di Milano with an interdisciplinary scholarship between the Department of Civil and Envirnomental Engineering and the Department of Mathematics. Lorenzo has a Master of Science in Civil Engineering For Risk Mitigation obtained in 2019. In his free time\, Lorenzo loves playing football and doing trail running.
