Abstract

Infiltration is the process in which water enters the soil from rainfall, irrigation, and snowmelt and it is useful to estimate the surface runoff, groundwater recharge, evapotranspiration, soil erosion, and transport of chemicals in a surface or subsurface flow (Ahaneku, 2011). The rate at which water infiltrates into the soil is known as the infiltration rate whereas the cumulative infiltration is the total depth of infiltrated water at a time. Infiltration rate varies from soil to soil as well as varies according to the type of land use and land cover. Further, it is influenced by variation in the soil organic matter, porosity, bulk density, specific gravity, unsaturated or saturated hydraulic conductivity, soil water retention characteristics, and the antecedent soil moisture conditions of various layers of the soil profile (Stolte, 2003; Shougrakpam et al., 2010; Ayu et al., 2013; Osuji et al., 2010).
