With the aim of characterizing complex solute transport problems in porous media, a two-dimensional physical model has been designed and constructed and is described in this paper along with some results relative to the estimation of the dispersive parameters and the pore water velocity. The experimental setup, simulating a fixed bed, uses a transmitted light imaging technique in conjunction with a fluorescent dye tracer (sodium fluorescein) to monitor solute movements.

Abstract
With the aim of characterizing complex solute transport problems in porous media, a two-dimensional physical model has been designed and constructed and is described in this paper along with some results relative to the estimation of the dispersive parameters and the pore water velocity. The experimental setup, simulating a fixed bed, uses a transmitted light imaging technique in conjunction with a fluorescent dye tracer (sodium fluorescein) to monitor solute movements.
