Which term describes the process of water seeping into the ground and replenishing groundwater?

Groundwater recharge happens when water from precipitation infiltrates the soil and moves downward to replenish the groundwater. The term for that downward movement through soil and rock is percolation. As water travels through pore spaces and fractures, driven by gravity and pressure, it reaches the water table and recharges aquifers. Runoff describes water flowing over the surface rather than into the ground; condensation is water vapor turning into liquid, and transpiration is water loss from plants. These processes don’t describe groundwater replenishment.
