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 ...
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 ...
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 ...
Calibración hidrodinámica de una estructura de biorretención estándar, sin vegetación, para la determinación del espesor óptimo de la capa de almacenamiento para un evento de lluvia típico de una zona urbana de Bogotá
(Escuela Colombiana de Ingeniería Julio GaravitoMaestría en Ingeniería Civil con Énfasis en Recursos Hidráulicos y Medio Ambiente, 2016)
In the intent to propose a standard bioretention system in Bogota city and in order to apply the inverse solution methodology on Hydrus – 1D, it is mandatory to determine each θ_s; θ_r; α;n and k_s parameters in 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) ...
Fractal-based models for the unsaturated soil hydraulic functions
(2017-11-15)
Reliable estimates of the unsaturated soil hydraulic properties are needed in many research and engineering projects. Fractal based approaches have become popular for describing the hydraulic functions. New models based ...
Modeling the unsaturated flow associated with a border irrigation event on an alfalfa plot
(Universidad de Cuenca, 2013-06)
HYDRUS-1D, a one dimensional water movement and solute transport model, was applied to analyze
a border irrigation event in an alfalfa plot located in the irrigation district of "La Violada" (Spain). The
research encompassed ...
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 ...
