The contribution of this work is the simulation of contaminated ground water developed from models about the disposal of severely contaminated material, i.e. radioactive fuels or chemical waste products. The model is based on equations for convection-diffusion-dispersion reactions. The equation in the present book is used for the modelling of a radionuclide transport of pollutants in ground water as well as for chemical irreversible reactions. While solving such problems, so-called multi-scale processes arise. Conventional treatment of black-box discretisation and solution methods are impossible or complicated. Hence, physically motivated methods are used, i.e. to integrate one-dimensional analytical solutions of convection-reaction equations. Especially so-called decomposition methods were emphasized.These methods decouple the different scales and solve the equations based on scales with each other. Therefore the previous coupling errors between the terms of the equations can be controlled and minimised with iterative methods. Furthermore, analytical solutions could be used for comparisons with the numerical solutions. In this work the theoretical derivations of solutions as well as their application in numerical methods for realistic calculations could be acquired. The methods were assembled in a program package that had been developed in a project to evolve a program for modelling the transport of pollutants in ground water. Some realistic damage events could be calculated based on dates from the partner GRS in Braunschweig, Germany. 606 $aGroundwater$xPollution$xSimulation methods 606 $aHazardous waste sites$xSimulation methods 606 $aGroundwater$xPollution$xMathematical models 606 $aDispersion$xMathematical models 606 $aDiscrete-time systems$xMathematical models 606 $aDiscrete geometry 615 0$aGroundwater$xPollution$xSimulation methods. 615 0$aHazardous waste sites$xSimulation methods. 615 0$aGroundwater$xPollution$xMathematical models. 615 0$aDispersion$xMathematical models. 615 0$aDiscrete-time systems$xMathematical models. 615 0$aDiscrete geometry. 676 $a363.739/4 700 $aGeiser$b Jurgen$0719323 801 0$bMiAaPQ 801 1$bMiAaPQ 801 2$bMiAaPQ 906 $aBOOK 912 $a9910959309003321 996 $aGroundwater contamination$94478249 997 $aUNINA
