The geological meaning of percolation is the slow movement of water through the pores in soil or rocks.
The movement of rain water vertically down through the soil.
The flow or trickling of a liquid downward through soil or filtering medium. The liquid may or may not fill the pores of the medium.
The act of surface water infiltrating into and through the ground.
The movement (normally downward) of water through and out of the soil. This downward movement accentuates the leaching process.
the slow passage of a liquid through a filtering medium; "the percolation of rainwater through the soil"; "the infiltration of seawater through the lava"

The movement of water downward and in a circular direction through subsurface soil layers, usually continuing downward to ground water. Can also involve upward movement of water. Slow seepage of water through a filter.
The downward movement of water through the soil, primarily because of gravity.
the actual movement of subsurface water either horizontally or vertically; lateral movement of water in the soil subsurface toward nearby surface drainage feature (e.g. stream) or vertical movement through the soil to groundwater zone.
Downward movement of water through the soil profile or other substance.
