Alternative Analytical Expressions for the General van Genuchten-Mualem and van Genuchten-Burdine Hydraulic Conductivity Models
(SOIL SCI SOC AMER, 2011)
The van Genuchten expressions for the unsaturated soil hydraulic properties, first published in 1980, are used frequently in various vadose zone flow and transport applications assuming a specific relationship between the ...
Further tests of the HYPROP evaporation method for estimating the unsaturated soil hydraulic properties
(2018-06-01)
Many soil, hydrologic and environmental applications require information about the unsaturated soil hydraulic properties. The evaporation method has long been used for estimating the drying branches of the soil hydraulic ...
Modeling of transpiration reduction in van Genuchten-Mualem type soils
(AMER GEOPHYSICAL UNION, 2009)
We derive an analytic expression for the matric flux potential (M) for van Genuchten-Mualem (VGM) type soils which can also be written in terms of a converging infinite series. Considering the first four terms of this ...
Using splines in the application of the instantaneous profile method for the hydrodynamic characterization of a tropical agricultural Vertisol
(Sociedade Brasileira de Ciência do Solo, 2022)
Evaluación de los parámetros hidráulicos (Mualem-van genuchten) de la capa orgánica a través de una modelación inversa en un bosque húmedo de montaña en el sur del Ecuador
(Loja: Universidad Nacional de Loja, 2016)
Estudo da curva de retenção e condutividade hidráulica estimadas pela equação de van Genuchten (1980) para diferentes tipos de solo
(Universidade Federal do Espírito SantoBREngenharia CivilPrograma de Pós-Graduação em Engenharia CivilUFES, 2012-10-25)
The van Genuchten (1980) equation has been widely used in the literature to represent analytically the soil water retention curve, and there are several published database tables which allow estimate the van Genuchten ...
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) ...
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 ...
Modelación de la dinámica del transporte de nitratos (NO3-) en suelo de un proceso de floricultura, ubicado en la Sabana de Bogotá
(Bogotá - Ingeniería - Maestría en Ingeniería - Recursos HidráulicosUniversidad Nacional de Colombia - Sede Bogotá, 2020-08-19)
Recently, the use of simulation tools has become more significant for decision-making, in the management of environmental services and impacts associated with anthropic activities in ecosystems. These tools allow to know ...
