Infiltration of Water into Nonuniform Soil

Journal of the Irrigation and Drainage Division, 1969
A simplified procedure for calculating infiltration into soil of nonuniform water content or hydraulic conductivity, or both, is presented. The procedure is based on the Green and Ampt model of piston flow. Input data consist of the difference in water content before and after wetting, the hydraulic conductivity after wetting, and the water entry value

Perfluorinated Compounds in Infiltrated River Rhine Water and Infiltrated Rainwater in Coastal Dunes

Environmental Science & Technology, 2010
Different studies have shown that surface waters contain perfluorinated compounds (PFCs) in the low ng/L range. Surface waters are used to produce drinking water and PFCs have been shown to travel through the purification system and form a potential threat to human health.

An Infiltration Equation to Assess Cropping Effects on Soil Water Infiltration

Soil Science Society of America Journal, 1994
Abstract The effect of crop plants on the infiltration of water into soil has been difficult to characterize. This study was conducted to determine whether a new three‐parameter infiltration equation, obtained from a recent infiltration quasi solution, could be validated and used for improved characterization of ...

Infiltration and Water Depletion in Lysimeters

Soil Science Society of America Journal, 1969
Abstract Evapotranspiration losses from five lysimeters with different plant species were estimated. Prediction equations were developed and used to estimate soil water regimens, infiltration and runoff in lysimeters with vegetative cover.

Electrodialysis and nanofiltration of surface water for subsequent use as infiltration water

Water Research, 2003
In order to achieve stable groundwater levels, an equilibrium between the use of groundwater for drinking water production and natural or artificial groundwater recharge by infiltration is needed. Local governments usually require that the composition of the water used for artificial recharge is similar to the surface water that is naturally present in

Water infiltration in porous materials

Journal of the Franklin Institute, 1992
Water infiltration in porous materials is investigated. A highly nonlinear hydraulic diffusivity function is considered in the physical model. The orthogonal collocation method is employed for solving the governing nonlinear differential equation. Because of its high accuracy, computational stability and easy application, the orthogonal collocation ...

Effects of White Grubs on Soil Water Infiltration

Neotropical Entomology, 2015
Water infiltration rates k were measured in mesocosms with soil and "white grubs" of Ancognatha falsa (Arrow) (Coleoptera: Melolonthidae). Three third instars of A. falsa and three adult earthworms Pontoscolex corethrurus were selected, weighted, and introduced into the mesocosms setting three treatments: soil + A. falsa, soil + P.

WATER INFILTRATION THROUGH DIESEL-CONTAMINATED SOIL

Journal of Environmental Science and Health, Part A, 2002
The water infiltration characteristics through soil contaminated by diesel was investigated. Columns were packed with soil containing 15, 10, 5, 1, and 0 percent diesel on mass basis. Two soil types were used, namely, clay loam and sand. The results showed that the water infiltration rate through clay loam soil containing 1 percent diesel was about 50 ...
