Detailed explanation-1: -Infiltration is one of the main processes determining groundwater recharge. The term is used to describe a downward moisture flow under the influence of gravity, through a porous medium. The infiltrating water comes from atmospheric precipitation, slope discharge, irrigation and, in some cases, river runoff.
Detailed explanation-2: -When infiltration is unable to replace groundwater as quickly as pumping removes it, the water table drops. Deeper wells could be dug to chase the table, but then the water table will just drop even further.
Detailed explanation-3: -Infiltration is the physical process involving movement of water through the boundary area where the atmosphere interfaces with the soil. The surface phenomenon is governed by soil surface conditions. Water transfer is related to the porosity of the soil and the permeability of the soil profile.
Detailed explanation-4: -Infiltration is defined as the flow of water from aboveground into the subsurface. The topic of infiltration has received a great deal of attention because of its importance to topics as widely ranging as irrigation, contaminant transport, groundwater recharge, and ecosystem viability.
