Infiltration of Water into Soil

2018
Infiltration is the process of water entry into soil; it is the basic process supplying the soil root zone with water. Infiltration as a process can be divided into two basic types: rain infiltration and ponding infiltration (infiltration from ponds on the soil surface).

Infiltration in Unsaturated Soils

1984
The physics of infiltration based on one and two phase-flow approaches are discussed. Quasi-analytical and numerical solutions of infiltration equations are reviewed and illustrated by several examples. An emphasis is put on field infiltration studies including statistical and geostatistical data analysis, stochastic modeling through the scaling theory.

Modeling infiltration in hysteretic soils

Advances in Water Resources, 1990
Abstract Existing vertical infiltration models either assume a constant infilatration rate at the soil surface and a unique set of soil-water functional relationships (hysteresis is neglected), or use empirical expressions which disregard physical laws.

Rainfall Infiltration into Unsaturated Soil

2015
As a tropical country, Malaysia is in the region of residual unsaturated soil. The prolonged and high intensity of rainfall will affect the parameters such as pore water pressure and moisture content of soil. This paper presents the experimental test result of rain water infiltration into soil column for unsaturated soil.

Infiltration, runoff and soil classifications

Journal of Hydrology, 1963
Abstract Infiltration is a factor in the estimation of flood peaks and yields of catchments. The role of infiltration in these estimations is discussed, together with the field problems associated with the use of such data. Some methods of classifying soils are described, and an assessment is made of the resulting soil maps for hydrologic purposes ...

Water Infiltration into the Soil

2019
The infiltration of water into soils is first studied for homogeneous soils for a better understanding of the process, and later cases of heterogeneous soils are introduced in the discussion. The simplest case, horizontal infiltration, is studied analytically with the solution of differential equations that govern the process.

Vertical infiltration in dry soil

Water Resources Research, 1977
An approximate method is proposed to integrate the ordinary differential equations governing the terms in Philip's (1957) series formulation of the water content profile. The method is related to the weighting solution used earlier (Brutsaert, 1976) for the sorption problem, and it is intermediate between the quasi‐steady state method and the sharp ...

Infiltration Into Increasingly Permeable Soils

Journal of the Irrigation and Drainage Division, 1976
A tabular procedure, based on the Green-Ampt equation, is developed to calculate infiltration into soil that becomes more permeable with depth. The procedure is simple and the results compare favorably with those obtained with a digital computer.
