摘要：
We study the adaptive finite element method to solve singular parabolic equations of porous media type and of nonstationary infiltration. We first prove a posteriori error estimates that especially take into account the discretization and algebraic errors. Furthermore we propose a robust adaptive method and apply this method to saturated/unsaturated porous media flow in an aquifer coupled with a root extraction process.
