After introducing the ADR equations and discontinuous Galerkin discretization, robust residual-based a posteriori error estimators in space and time are derived. The elliptic reconstruction technique is then utilized to derive the a posteriori error bounds for the fully discrete system and to obtain optimal orders of convergence. As coupled surface and subsurface flow over large space and time scales is described by (ADR) equation the methods described in this book are of high importance in many areas of Geosciences including oil and gas recovery, groundwater contamination and sustainable use of groundwater resources, storing greenhouse gases or radioactive waste in the subsurface.Lecture Notes in Geosystems Mathematics and Computing,2730-5996Numerical analysisPartial differential equationsGeophysicsNumerical Analysishttps://scigraph.springernature.com/ontologies/product-market-codes/M14050Partial Differential Equationshttps://scigraph.springernature.com/ontologies/product-market-codes/M12155Geophysics/Geodesyhttps://scigraph.springernature.com/ontologies/product-market-codes/G18009Numerical analysis.Partial differential equations.Geophysics.Numerical Analysis.Partial Differential Equations.Geophysics/Geodesy.510Uzunca Muratauthttp://id.loc.gov/vocabulary/relators/aut755791BOOK9910254069703321Adaptive discontinuous Galerkin methods for non-linear reactive flows1523057UNINA
