Resumo: To model water flow and solute transport in soils, hydrodynamic and hydrodispersive parameters are required as input data in the mathematical models. This work aims to estimate the soil hydraulic and solute transport properties using a ponded axisymmetric infiltration experiment using a single-ring infiltrometer along with a conservative tracer (Cl-) in the field. Single ring infiltration experiments were accomplished on an Oxisol in Areia in the state of Paraíba, Brazil (6o 58' S, 35o 41' W, and 645 m), in a 50 x 50 m grid (16 points). The unsaturated hydraulic conductivity (K) and the sorptivity (S) were estimated for short or long time analysis of cumulative three-dimensional infiltration. The single tracer technique was used to calculate mobile water fraction (Ф) by measuring the solute concentration underneath the ring infiltrometer at the end of the infiltration. Two solute transfer numerical models based on the mobile-immobile water concept were used. The mobile water fraction (Ф), the dispersion coefficient (D), and the mass transfer coefficient (a) between mobile and immobile were estimated from both the measured infiltration depth and the Cl- concentration profile underneath the infiltrometer. The classical convection-dispersion (CD) and the mobile-immobile (MIM) models showed a good agreement between calculated and experimental values. However, the lowest standard errors to the fitted parameters were obtained by the CD model.

Este trabajo tiene como objetivo estimar las propiedades hidráulicas y de transporte de solutos del suelo utilizando un experimento de infiltración simétrica de eje utilizando un infiltrómetro de anillo único junto con un trazador conservador (Cl-) en el campo. Se realizaron experimentos de infiltración de anillos simples en un Oxisol en Areia, en el estado de Paraíba, Brasil (6°58'S, 35°41'W y 645 m), en una cuadrícula de 50x50 m (16 puntos). La conductividad hidráulica insaturada (K), y los sorbidos (S), se estimaron analizando el tiempo largo y corto de la infiltración tridimensional acumulada. Se utilizó la técnica del trazador único para calcular la fracción de agua móvil, Ф, midiendo la concentración de soluto debajo del infiltrómetro de anillo al final de la infiltración. La fracción de agua móvil (Ф), el coeficiente de dispersión (D) y el coeficiente de transferencia de masa (a) entre agua móvil e inmóvil se estimaron a partir de la profundidad de infiltración medida y el perfil de concentración de Cl- debajo del infiltrómetro de anillo. Los modelos de convección-dispersión (CD) y móvil-inmóvil (MIM) lograron una buena concordancia entre los valores calculados y medidos. Sin embargo, los errores estándar más bajos para los parámetros ajustados se obtuvieron para el modelo de CD.Para modelar o fluxo de água e o transporte de solutos no solo, parâmetros hidrodinâmicos e hidrodispersivos são necessários como dados de entrada nos modelos matemáticos. Este trabalho tem como objetivo estimar as propriedades hidráulicas e de transporte de soluto do solo por meio de um experimento de infiltração axissimétrica utilizando um único anel como infiltrômetro juntamente com um traçador conservador (Cl-) em campo. Experimentos de infiltração em anel simples foram realizados em um Latossolo em Areia, Paraíba, Brasil (6°58'S, 35°41'W e 645 m), em uma malha de 50x50 m (16 pontos). A condutividade hidráulica insaturada (K), e a sorvidade (S), foram estimadas pelas análises dos tempos longo e curto da infiltração tridimensional cumulativa. A técnica de traçador único foi usada para calcular a fração de água móvel, Ф, medindo a concentração de soluto abaixo do infiltrômetro no final da infiltração. Dois modelos numéricos de transferência de soluto baseados no conceito de água móvel-imóvel foram usados. A fração de água móvel (Ф), o coeficiente de dispersão (D) e o coeficiente de transferência de massa (a) entre a água móvel-imóvel foram estimados a partir da profundidade de infiltração medida e do perfil de concentração de Cl- abaixo do infiltrômetro de anel. Os modelos de convecção-dispersão (CD) e móvel-imóvel (MIM) alcançaram uma boa concordância entre os valores calculados e medidos. No entanto, os menores erros padrão para os parâmetros ajustados foram obtidos para o modelo CD.Research, Society and Development2021-10-30info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://rsdjournal.org/index.php/rsd/article/view/2176410.33448/rsd-v10i14.21764Research, Society and Development; Vol. 10 No. 14; e195101421764Research, Society and Development; Vol. 10 Núm. 14; e195101421764Research, Society and Development; v. 10 n. 14; e1951014217642525-3409reponame:Research, Society and Developmentinstname:Universidade Federal de Itajubá (UNIFEI)instacron:UNIFEIenghttps://rsdjournal.org/index.php/rsd/article/view/21764/19493Copyright (c) 2021 André Maciel Netto; Suzana Maria Gico Lima Montenegro; Ademir de Jesus Amaralhttps://creativecommons.org/licenses/by/4.0info:eu-repo/semantics/openAccessNetto, André Maciel Montenegro, Suzana Maria Gico Lima Amaral, Ademir de Jesus2021-12-04T11:48:39Zoai:ojs.pkp.sfu.ca:article/21764Revistahttps://rsdjournal.org/index.php/rsd/indexPUBhttps://rsdjournal.org/index.php/rsd/oairsd.articles@gmail.com2525-34092525-3409opendoar:2024-01-17T09:41:06.778240Research, Society and Development - Universidade Federal de Itajubá (UNIFEI)false
