INFILTRATION “The surface entry of water into the soil”

Despite strict definition, infiltration is really a 3-phase process: 1.Surface Entry 2.Transmission 3.Soil Storage Depletion

Volume of voids occupied by water Total volume of soil 18 Minutes

Volume of voids occupied by water Total volume of soil 159 Minutes
