Each catchment area has its own peculiar infiltration features, depending on its climate and soil structure This research is a study and comparison of the banks of two permanent rivers of Bushehr Province (Iran), namely, the Mond and the Bahoosh, in the County of Tangestan. In order to determine and check the best penetration model and to calculate the infiltration coefficients of the Kostyakov-Lowese, SCS, and Philip models, the vertical water penetration rate of the soil was measured using field Double Ring tests (repeated for three times) in 60 test pits. Using computing software, the infiltration and aggregate infiltration rates’ curves were drawn and a Visual Basic software program was used for each model to specify the best coefficients, that is, those with the highest correlation with the curves. Results show that, for the Bahoosh riversides, the American SCS infiltration model has less errors than the Philip and Kostyakov-Lowese models, and for the Mond riversides, the Philip model is better than the Kostyakov-Lowese and American SCS models.
