The efficiency of some infiltration models in three rangeland conditions(case study:Savojbolagh rangelands)

摘要：

Introduction Infiltration is one of the important hydrological processes and its accurate quantification is essential for many studies.Infiltration can be either measured in the field or estimated using mathematical models which vary from empirical to physically based models,including physically based models ( e.g.Green and Ampt,1911,Richards,1931,Philip,1957,Morel-Seytoux,1978,Haverkamp et al.,1990 and Corradini et al.,1994),conceptual models (e.g.Nash,1957 and Diskin and Nazimov,1995 ),or empirical relations ( e.g.Horton,1933,Kostiakov,1932,Holtan,1961 and Soil Conservation Service-USDA,1972) (Chahinian et al.,2005).The objective of this paper is to compare the performance of three widely used infiltration models with infiltration measured in Central Iran.
