Determination of infiltration models parameters for silty loam soil by data analysis

Infiltration flow is an important process in the global water cycle. In order to investigatethe movement of the water flow in the unsaturated soils, infiltration parameters must bedetermined. Various models of infiltration have been proposed by a number ofresearchers. Some of infiltration models are well known for hydrologists. In this paper,infiltration parameters for models SCS, Green-Ampt, Horton and Philip are obtained bythe data analysis and the curve fitting. The considered soil in this research is silty loam.the data analysis results for these infiltration models are presented by the root meansquare error (RMSE). The RMSE values for all infiltration models are very close to zeroand therefore, a good agreement between the observed and estimated data is created bycurve fitting.
