INCOH/SAR-13/97-Infiltration and its simulation

Abstract

Infiltration.is the term applied to the process of water entry into the soil, generally by downward flow through all or part of the soil surface. Water may enter the soil through the entire surface uniformly as under ponding or rain or it may enter the soil through furrows or crevices. The rate of this process, relative to the rate of water supply, determines how much of water, if any, will run off. Infiltration not only affects the recharge of soil profile and ground water but, also the amount of surface runoff and subsequently soil erosion. For efficient soil and water management, knowledge of infiltration process, therefore, forms an essential prerequisite.
