Numerical modelling of non equilibrium reactive transport in acid mine drainage

Abstract

The conventional computational models on solute transport use the simple advection diffusion equation to simulate the contaminant movement in subsurface however the equation has some limitations since some processes cannot be simulated like occurrence of non equilibrium in mass distribution during transport through the porous medium This happens due to the presence of stagnant immobile water at the disconnected pores dead end pores of porous medium where the velocity of the stagnant wat...
