The Mixing of Groundwaters of Different Compositions in Cracked-Porous Media

The mass transfer of groundwaters of different compositions in saturated cracked-porous media has been studied for the case of one-dimensional filtration. The solubility of the porous matrix substance due to the influence of the liquid entering the medium through the cracks has been taken into account. Using the Laplace transformation, an analytical solution to the problem of determining the concentration of the solute generated during such mass transfer has been obtained. The results of the corresponding calculations for the solute concentration distribution at different time points are given.
