An experimental and modeling study of solute transport and diffusion in a two-layer aquifer/aquitard system

In situ electrical conductivity measurement of solute concentration to quantify solute diffusion in clays in laboratory experiments

Three types of injection concentration boundary conditions: step change, linear decrease, and a CSTR for exponential decrease

One-dimensional analytical solution for solute diffusion through an aquitard and advective transport in an aquifer

Analytical solution in good agreement with experimental data
