Abstract: 

Fried-Combernous and Brigham models are two of the important models for nonreactive contaminant transport in saturated, homogeneous porous media under steady-state uniform flow. These models are proposed for computing dispersivity in long and short distances respectively. In this research, dispersivity of coarse and medium homogeneous sands is investigated by these two models. Experiments were. carried out in a rectangular laboratory- scale Plexiglass tank, 0.72 m long, 0.1 m wide and 1.2 m high. A solution containing 8 g/l (EC=14 dS/m) sodium chloride concentration was used as the non-reactive contaminant. Experiments were carried out with soil thicknesses of 0.1 m in sequence up to a final thickness of 1 m. A total of 110 dispersivity values obtained from using. these models were compared. The results indicated that for long travel, dispersivity obtained from these two models are equal for homogeneous sands used in these experiments. Therefore we can conclude that Brigham model can be used for long travel case with the same accuracy as Fried-Combernous model. Also in long travel distance, the dispersivity values calculated by Fried-Cambernous model with the pollutant velocity and actual velocity are equal. The results indicated that as in short travel distances, with decreasing values of b, time to reach 0.5 C/C0 occurred at less pore volume. But in long travel distances, time to reach 0.5 C/C0 occurred at more than one pore volume.
