Estimating of soil infiltration indexes is necessary for appropriate irrigation design and management. In this regard, different empirical and physical equations have been developed for simulation of infiltration in surface irrigation. In this study, six extracting method of infiltration equation in furrow and estimating final intake in Lavark field of Isfahan University of technology was performed and the rate of surface storage change has been calculated. Information were collected, among three replications and five furrow irrigation event, double ring and Guelph permeameter test, include cross-section, advance, recession, inflow and outflow rates, in addition to infiltration changes in submerged static condition and hydraulic conductivity of soil. The results were analyzed using a randomized complete block design. The results indicated that final intake rates drived from the input-output method (about 17mm/hr) were considerabely more than the one that obtained by cylindrical and Guelph penetrometer methods,(about 6mm/hr) whose diferenses were statisticaly significant. Also, the study of infiltration process related to the various equations showed that there is high statistically significant difference at level of one percent in estimation of average infiltration in different time intervals of five using these equations. The most infilteration rate is related to volume balance equation and the least value was observed in input-output method results. Generally, the equations with polynomial-power function estimated greater infiltration rate than simple power equations. This study showed that it is necessary to operate the farm experimentals corresponding with the applicational conditions of farm.
