Correspondence between theory and practice of a Beerkan infiltration experiment

The Beerkan infiltration experiment is carried out by inserting the ring a short depth into soil and establishing positive head of water on surface for at least part run. Nevertheless, data are analyzed assuming fully unconfined process (ring insertion depth, d = 0 cm) null ponded (H cm). influence an 2 h sampled every minute was tested in this numerical investigation. Five soils varying from sand to silt loam, three radii (5–15 cm), Beerkan-specific range values both H (between 1 were considered. differences between theoretical (d practical setups varied −10.4 +8.6% mean rate −10.2 +8.3% final cumulative infiltration. These small, they decreased absolute value considering soil-dependent radius. In particular, nearly negligible detected using small coarse-textured large fine-textured soils. coarser soils, did not alter estimated coefficients two-parameter model appreciably with linearization method, because these differed no more than 9.2%. fine could be possible regardless considered setup, or it use cm instead that impeded convincing data. conclusion, good correspondence, many circumstances, reinforced interest simple as means collect field.
