Vertical flow of solute in porous media preferential flow is studied and compared with Darcys flow. The methodology used for the study is experimental. The laboratory model used is similar to Darcy apparatus with slight modification. The study has compare measured velocity of first reach of solute with average velocity of flow in porous media. The laboratory model consists of 150 mm diameter High density Polyethylene pipe of 750 mm height filled uniform sand. Nine sets of experiment is conducted with 3 types of sand D10 0.6 mm and Cu 1.42 D10 0.11 mm and Cu 1.55 D10 0.3 mm and Cu 1.4 and 3 types of brine concentration 5 10 20 by weight brine solution. Brine solution is found to be 1.13 to 1.84 times faster than average velocity of flow as a result of preferential flow.
