Soil infiltration
= Soil infiltration
Entry of surface water into soil pore space. The <soil infiltration>[infiltration] rate depends on water availability, soil permeability, capillary suction and the existing moisture profile. In a shallow overland-flow model it is a sink from the surface layer, distinct from <evaporation> into the atmosphere. An imposed <soil infiltration>[infiltration] capacity cannot remove more liquid than is locally available.
