Resumo: The determination of the hydraulic and hydrodispersive properties of soil is necessary for the understanding of water dynamics and soil solute transport, and they are used as input data in several models. Determinations of soil hydraulic and hydrodispersive parameters are usually obtained by separate methodologies. Axisymmetric infiltration tests using a single ring infiltrometer with a conservative tracer (KBr) in the field (Beerkan-Solute) lead to the determination of the most realistic hydraulic and hydrodispersive properties of the study area. The objective of this work was the hydrodynamic and hydrodispersive characterization of an irrigated soil, classified as Fluvic Cambisol, from the lowland areas of the northeastern semi-arid region, located in the backwoods of the state of Pernambuco, in the municipality of Serra Talhada-PE. The hydrodispersive parameters were determined with the CXTFIT 2.0 program, using the CDE and MIM models. The studied soil presented hydrodynamic characteristics with high values of sorptivity (S) that were associated with high values of saturated hydraulic conductivity (Ks), indicating that the soil has good permeability and resistance to surface crumbling caused by rain drops or soil management. It was observed the predominance of the convective process, being the CDE model the one that presented the best performance in the transport of the KBr tracer under field conditions, indicating the absence of two water regions mobile and immobile in the studied soil.

As determinações dos parâmetros hidráulicos e hidrodispersivos do solo são normalmente obtidas por metodologias separadas. A realização de ensaios de infiltração axissimétrica utilizando um infiltrômetro de anel simples com um traçador conservativo (KBr) em campo (Beerkan-Soluto) conduz a determinações das propriedades hidráulicas e hidrodispersivas mais realistas da área em estudo. Este trabalho teve como objetivo a caracterização hidrodinâmica e hidrodispersiva de um solo irrigado, classificado como Cambissolo Flúvico, em áreas de baixios da região do Semiárido nordestino, situado na microrregião do Sertão Pernambucano, no município de Serra Talhada-PE. As determinações dos parâmetros hidrodispersivos foram realizadas com o programa CXTFIT 2.0, com uso dos modelos CDE e MIM. O solo estudado apresentou característica hidrodinâmica retratada em altos valores de sorvidade (S) associados a altos valores de condutividade hidráulica saturada (Ks), indicando que o solo apresenta boa permeabilidade e resistência ao encrostamento superficial, provocado por gotas de chuva ou manejo do solo. Observou-se o predomínio do processo convectivo, sendo o modelo CDE o que apresentou melhor desempenho no transporte do traçador KBr em condições de campo, indicando a ausência de duas regiões água móvel e imóvel no solo estudado.  Universidade Federal Rural do Semi-Árido2020-02-14info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://periodicos.ufersa.edu.br/caatinga/article/view/844810.1590/1983-21252020v33n118rcREVISTA CAATINGA; Vol. 33 No. 01 (2020); 160-171Revista Caatinga; v. 33 n. 01 (2020); 160-1711983-21250100-316Xreponame:Revista Caatingainstname:Universidade Federal Rural do Semi-Árido (UFERSA)instacron:UFERSAenghttps://periodicos.ufersa.edu.br/caatinga/article/view/8448/10166Copyright (c) 2020 Revista Caatingainfo:eu-repo/semantics/openAccessPalácio Filho, Albedson Miranda Maciel Netto, AndréCorrêa, Marcus MetriRolim Neto, Fernando CartaxoSilva, Lívia Previatello daMalta, Sanderson Hudson da Silva2023-07-20T18:32:05Zoai:ojs.periodicos.ufersa.edu.br:article/8448Revistahttps://periodicos.ufersa.edu.br/index.php/caatinga/indexPUBhttps://periodicos.ufersa.edu.br/index.php/caatinga/oaipatricio@ufersa.edu.br|| caatinga@ufersa.edu.br1983-21250100-316Xopendoar:2024-04-29T09:46:40.018551Revista Caatinga - Universidade Federal Rural do Semi-Árido (UFERSA)true
