Dos métodos para estimar las propiedades hidráulicas del suelo a partir de: un proceso de (I) humectación por capilaridad más evaporación, y (II) humectación por capilaridad con multitensión: análisis teórico

Abstract

[EN] The determination of the soil water retention curve, θ(h), and the saturated hydraulic conductivity, Ks, are of paramount importance to correctly characterize the vadose zone. This communication presents two methods to estimate Ks and the water retention curve α and n parameters from: (i) a capillary rise wetting process at saturation followed by an overpressure step, plus an evaporation process, taking into account the hysteresis phenomena; and (ii) a capillary wetting process at negative tension plus a saturation step. The theoretical analysis was performed on a 5-cm diameter and 5 cm high cylinder of loam soil, using the HYDRUS-2D software. The responses surfaces of the objective function (Ks, α, n) for the planes Ks-α, α-n and Ks-n obtained with both methods showed a unique and well defined minimum, which indicates these methods allow accurate estimates of the soil hydraulic properties.

[ES] La determinación de la curva de retención θ(h) y conductividad hidráulica saturada (Ks) del suelo es fundamental para caracterizar la zona no saturada. Esta comunicación presenta dos métodos para estimar Ks y los parámetros α y n de θ(h) a partir de: (i) un proceso de humectación por capilaridad a saturación seguido de una sobre-presión, más un proceso de evaporación, considerando el fenómeno de histéresis, y (ii) un proceso de humectación por capilaridad a tensión negativa seguida de una tensión a saturación. El análisis inverso se realizó sobre un cilindro de 5 cm de altura y 5 cm de diámetro con suelo franco, utilizando el programa HYDRUS-2D. Los mapas de error de la función objetivo (Ks, α, n) para los planos Ks-α, α-n y Ks-n obtenidos para ambos métodos mostraron un único mínimo, lo que indica que estos métodos permiten estimar de forma precisa los parámetros hidráulicos del suelo.
