%0 Journal Article %T Pollution in porous media: non permanent cases %A Lamine Ndiaye %A Alassane Sy %A Diaraf Seck %J Journal of Computations & Modelling %D 2012 %I Scienpress Ltd %X In this work, we focus on pollution transfer in porous media. We prove that the pollutant transfer can be modeling by a non linear evolutive system. We used the mathematical frameworks presented on [5] to solve the non linear problem. And so we build a numerical scheme, based on topological optimization to get the representation of the pollution in the non permanent case. To end the paper, we give some numerical results. %K Pollution %K Porous media %K Topological optimization %U http://www.scienpress.com/Upload/JCM/Vol%202_1_3.pdf
