Abstract: In New Caledonia, the mine tailings are protected from flooding by ensuring the water flow through riprap. This study refers to high velocity flow in rockfill. It has been defined by the international firm of engineering consultants MECATER under contract with the Nickel Company of ERAMET group in New Caledonia (SLN), to be carried at the National Agronomic Institute of Tunis (INA Tunis) in collaboration with the Fluids Mechanics Institute of Toulouse (IMF Toulouse). In the frame of this study, many experiments in different types of porous media and under different hydrodynamics conditions were conducted at IMFT. In this paper we present our simulation results only for homogenous porous media made by spherical particle with mean diameter d=1 cm, It is observed that the porous media presented a variation of the permeability in different flow regimes. The main aim of this study is to restore the permeability variation curve as a function of the Reynolds number and simulate the experimental results by Forchheimer, Ergun and Barree and Conway relations. A comparative analysis between these equations was presented.
