Estimating Infiltration in Open‐ended Furrow Irrigation by Modifying Final Infiltration Rate
Irrigation and Drainage, 2022AbstractThe Kostiakov–Lewis equation is one of the commonly used infiltration equations in furrow irrigation. Elliott and Walker developed a two‐point method to estimate coefficients of the Kostiakov–Lewis equation. The basic infiltration rate (fo) in the Kostiakov–Lewis equation is usually calculated by the inflow–outflow method to determine the other

Science of The Total Environment, 2020
Managed aquifer recharge (MAR) systems can be designed and operated to improve water supply and quality simultaneously by creating favorable conditions for contaminant removal during infiltration through shallow soils. We present results from laboratory flow-through column experiments, using intact soil cores from two MAR sites, elucidating conditions ...

Infiltration Rates as Affected by Desert Vegetation
Water Resources Research, 1969Infiltration of water into two soils measured at radial distances from the stems of paloverde (Cercidium microphyllum) and creosote bush (Larrea tndentata) were found to average nearly three times greater under plants than in the openings. Bulk density was lower and organic matter content was higher in topsoil under plants than in the openings.

Hydrological Processes, 2006
AbstractThe infiltration rate in the unsaturated zone is analysed from a probabilistic point of view. It is shown that the empirical formulas of Horton and Kostiakov, without apparent physical basis, are explained in a probabilistic approach. Horton's formula reflects a Markovian process contrary to Kostiakov's formula.

Changes of steady-state infiltration rates in recurrent ponding infiltration experiments
Journal of Hydrology, 1988Abstract Ponding infiltration experiments on coarse acid brown soils (Cambisol) are described to show that the steady-state infiltration rate depends on the initial moisture content, which is in contrast with the theory. The effect is observed on three different scales: (1) in the field at randomly chosen places near grid points of a network for two ...

INFILTRATION RATE AS RELATED TO RAINFALL ENERGY
Canadian Journal of Soil Science, 1967Infiltration rate with respect to rainfall energy was determined on a Sceptre clay, Haverhill loam and Hatton fine sandy loam. The infiltration rate of saturated Sceptre clay dropped from 24.0 to 0.6 cm per hour with an application of 2.0 cm of simulated rain.

Determining infiltration rates in an irrigation border
Journal of Geophysical Research, 1960The relationship between the flow of water in an irrigation border and the infiltration rate of the soil as a function of time has been treated by previous authors, primarily by an analytical approach. A simple graphical construction is proposed whereby the time-infiltration curve can be constructed from data gathered in an irrigation border test under

New Carbon Materials, 2012
Abstract Carbon/carbon composites were fabricated by chemical vapor infiltration of needled carbon fiber felts (70% porosity) with natural gas as precursor at different infiltration pressures. The thermodynamics of methane pyrolysis and the densification kinetics were used to investigate the influence of infiltration pressure on the infiltration rate

Modeling the abnormally slow infiltration rate in mesoporous films
Physical Chemistry Chemical Physics, 2017The rate of infiltration of fluids into bimodal porous systems was modeled to decrease as the ratio of the pore size to pore neck size was increased.

The rate of infiltration of water in irrigation‐practice
Eos, Transactions American Geophysical Union, 1937(The data reported in this paper have been secured in the course of irrigation‐ and drainage‐investigations conducted, during 1926 and 1927, by the Idaho Agricultural Experiment Station and, since 1932, by the Oregon Agricultural Experiment Station, both in cooperation with the United States Bureau of Agricultural Engineering.)The rate of infiltration ...
