Constructing a mathematical model and studying numerically the effect of bio-clogging on soil filtration consolidation

Mathematical modeling and computer simulation methods have been used to investigate the extent of influence exerted by bio-clogging on dynamics excess head scattering in soil massif. To this end, classical equation filtration consolidation has modified for case variable porosity resulting from changes biomass. The numerical solution constructed mathematical model form a nonlinear boundary problem was derived finite-element method. Numerical experiments were carried out their analysis performed. Specifically, paper shows charts pressure differences array when neglecting estimating effects at specific points time. demonstrated that two years after onset process neighborhood lower limit examined mass with thickness 10 meters, heads fall initial value m 4 m. greatest impact clogging pores microorganisms is revealed an upper limit. At depth 1 m, t=180 days, difference reaches 2.4 This about 200 % distribution without taking into account bio-clogging. Over time, effect bacteria pressures decreases. However, extends entire mass, up Thus, t=540 limit, leads are 1.8 greater than pure water (a relative increase 80 %). Bio-clogging processes intensified as result development organic chemicals enter porous environment. Therefore, practical point view, studying them especially relevant household waste storage facilities stability bases. It advisable undertake research using
