Due to the fact that currently seepage losses are significant, even with use of such geosynthetic materials like polymer geomembrane, evaluation of water permeability polymeric screens the presence of small lesions remains a major challenge. To simulate the filtration damage geosynthetic polymer screens use software package "Somsol multiphysics», allowing to solve both two-dimensional (plan) and three-dimensional (spatial) problem stationary and non-stationary filtration.
