Simple functions for describing soil water retention and the unsaturated hydraulic conductivity from saturation to complete dryness
(2020-09-01)
Many applications require accurate soil hydraulic functions that can describe the dynamics of water in variably saturated systems from full saturation to complete dryness. Current functions considering zero water content ...
Development and evaluation of pedotransfer functions for saturated hydraulic conductivity using an international soil database
(Wageningen University and Research, 2018)
Different responses in bulk density and saturated hydraulic conductivity to soil deformation by logging machinery on a Ferralsol under native forest
(Blackwell Publishing, 2007-09-01)
Ferralsols have high structural stability, although structural degradation has been observed to result from forest to tillage or pasture conversion. An experimental series of forest skidder passes in an east Amazonian ...

A Simple Hysteretic Constitutive Model for Unsaturated Flow
(Springer, 2017-11)
In this paper, we present a constitutive model to describe unsaturated flow that considers the hysteresis phenomena. This constitutive model provides simple mathematical expressions for both saturation and hydraulic ...
Closed-form hydraulic conductivity equations for multimodal unsaturated soil hydraulic properties
(2022-01-01)
Closed-form expressions of the hydraulic conductivity function for linearly superposed subretention (multimodal) functions were derived for arbitrary sets of the Brooks and Corey (BC), van Genuchten (VG), and Kosugi (KO) ...
Methods for measuring field-saturated hydraulic conductivity
(INST MEXICANO TECHNOLOGIAAGUA, 2005)
Double-ring infiltrometer, constant-head well permeameter, tension infiltrometer, and Porchet methods are compared to determine field-saturated hydraulic conductivity, K-fs. K-fs values of steady-state methods, which were ...
Spatial relationship of the saturated hydraulic conductivity and rock fragments on the soil surface in an Andean microwatershed
