Fractal concepts in relation to soil water diffusivity
(Williams & Wilkins, 1997-11-01)
Fractal geometry would appear to offer promise for new insight on water transport in unsaturated soils, This study was conducted to evaluate possible fractal influence on soil water diffusivity, and/or the relationships ...
Relações físico-hídricas de um latossolo sob plantio direto
(Universidade Federal de Santa MariaBRAgronomiaUFSMPrograma de Pós-Graduação em Ciência do Solo, 2010-11-19)
Soil compaction is a process inherent in the no-tillage system and therefore, it will be always observed with varying intensity degrees. However, this system has features which can be maximized in order to reduce the ...
Modelagem do excedente de infiltração para avaliar a funcionalidade hidrológica do solo
(Universidade Federal de Santa MariaBrasilAdministraçãoUFSMPrograma de Pós-Graduação em AdministraçãoCentro de Ciências Rurais, 2017-07-28)
The soil ability to compartmentalize water in the hydrological cycle can be studied in terms of the soil physical quality and might be indicated by soil’s properties, attributes or process. Of these, the processes are more ...
Atributos químicos e microbiológicos de solos hidromórficos originados de basalto no sudoeste do Paraná
(Universidade Tecnológica Federal do ParanáDois VizinhosBrasilPrograma de Pós-Graduação em AgroecossistemasUTFPR, 2020-03-12)
Hydromorphic soils are located in places with surface water table and have functions to regulate water flow, recharge aquifers, natural corridors of native species and flora with typical species, therefore the protection ...
Unsaturated Infinite Slope Stability Considering Surface Flux Conditions
(ASCE-AMER SOC CIVIL ENGINEERS, 2010)
A slope stability model is derived for an infinite slope subjected to unsaturated infiltration flow above a phreatic surface. Closed form steady state solutions are derived for the matric suction and degree of saturation ...
A modeling framework to quantify the effects of compaction on soil water retention and infiltration
(2021-01-01)
The water retention curve (WRC) of arable soils from the southeastern United States at different levels of compaction (no compaction, and 10 and 20% increases in soil bulk density) was estimated using the van Genuchten–Mualem ...
Potential use of the veris apparent EC sensor to predict soil texture under the semi-arid conditions of central Arizona
(2009-12-01)
The operational details of the apparent electrical conductivity (ECa) sensor manufactured by Veris Technologies have been extensively documented in literature reports, but the geographical distribution of these research ...

Effect of soil textural characteristics on longitudinal dispersion in saturated porous media
(Sciendo, 2021-06-01)
This study focuses on the effects of soil textural heterogeneity on longitudinal dispersion under saturation conditions. A series of solute transport experiments were carried out using saturated soil columns packed with ...
