AbstractLaboratory experiments were conducted between two plexiglass, parallel plates, 121.9 cm long x 7.6 cm wide, to examine the relationship between dispersion and velocity as the aperture and roughness of the plates were varied. Experimental results from the smooth parallelplate model closely approximated the theoretical determination that dispersion was proportional to velocity squared. The velocity exponent, n, and dispersivity, a, remained constant as distance from the source increased. When various configurations of blockages and roughness were placed between the parallel plates, the velocity exponent and dispersivity did not remain constant with distance from the source. The velocity exponent decreased with distance from the source entrance to a value of 1.3 at 111.8 cm for two separate nonsmooth, parallel-plate designs. For these nonsmooth, parallel-plate designs, dispersion more nearly resembled flow through a porous medium instead of flow between parallel plates.
