Estimation of hydrodynamic properties of a sandy-loam soil by two analysis methods of single-ring infiltration data

Abstract Beerkan infiltration runs could provide an incomplete description of with reference to either the near steady-state or transient stages. In particular, process still be in stage at end run some data might loss. The Wu1 method and BEST-steady algorithm can applied derive soil hydrodynamic parameters even under these circumstances. Therefore, a dataset developed using two different analysis methods. hypothesis that yield similar predictions when they are same curve was tested this investigation. For sandy-loam soil, yielded higher saturated hydraulic conductivity, Ks , microscopic pore radius, λ m depth wetting front run, dwf lower macroscopic capillary length, c as compared method. Two corresponding means differed by 1.2–1.4 times, depending on variable, differences appeared overall from moderate relatively appreciable, is neither too high nor negligible any circumstance, according literature suggestions. estimates were (difference < 25%) gravity-driven vertical flow lateral components represented 71–89% total infiltration. conclusion, methods do not generally curve. However, it seems possible establish what conditions making similar.
