Avaliação da compressibilidade de um Nitossolo Vermelho distroférrico sob sistema plantio direto, preparo convencional e mata nativa Evaluation of compressibility of a dystroferric Red Nitosol under no-tillage and conventional tillage systems and a native forest

open access: yesRevista Brasileira de Ciência do Solo, 2005
Os efeitos do tráfego de máquinas nos atributos do solo de acordo com o tempo de adoção do sistema plantio direto são ainda pouco pesquisados em ambientes tropicais, e muitas dúvidas ainda persistem sobre a variação dinâmica da estrutura do solo e a sua ...

Low‐Rank Geostatistical Inversion for Spatiotemporal Heterogeneity of Aquitard Hydraulic Parameters

open access: yesWater Resources Research, Volume 61, Issue 12, December 2025.
Abstract Many hydrogeological processes are intricately linked to both the spatial heterogeneity and temporal dynamics of the involved parameters. The variability in hydrogeological parameters across both space and time domains is defined as the spatiotemporal heterogeneity.

Consolidômetro: equipamento pneumático-eletrônico para avaliação do estado de consolidação do solo Consolidometer: electronic-pneumatic equipment to evaluate soil consolidation

open access: yesRevista Brasileira de Ciência do Solo, 2007
A obtenção da pressão de preconsolidação (sigmap) se dá a partir de um método denominado ensaio de consolidação, cuja definição consiste no processo de transferência gradual de uma carga aplicada ao solo até que todos os vazios deste sejam comprimidos. O

Modeling Land Subsidence Under Future Water Stress: The Influence of Groundwater Exploitation, Climate Change, and Inter‐Basin Water Diversion

open access: yesWater Resources Research, Volume 61, Issue 11, November 2025.
Abstract Land subsidence driven by groundwater exploitation poses a critical threat under future water stress from population growth, urbanization, and economic expansion. While the relationship between groundwater level (GWL) fluctuations and land subsidence has been studied, limited research has explored their co‐evolution under future development ...

Characterizing Aquifer Properties Through a Sparse‐Grids‐Based Bayesian Framework and InSAR Measurements: A Basin‐Scale Application to Alto Guadalentín, Spain

open access: yesWater Resources Research, Volume 61, Issue 8, August 2025.
Abstract Aquifer characterization is essential for predicting aquifer responses and ensuring sustainable groundwater management. In this study we develop a sparse‐grids‐based Bayesian framework to infer the hydraulic conductivity and the soil compressibility of over‐exploited aquifer systems using Interferometric Synthetic Aperture Radar (InSAR) ground

Relações do parâmetro S para algumas propriedades físicas de solos do sul do Brasil Relationships of the S parameter of some physical properties of soils of southern Brazil

open access: yesRevista Brasileira de Ciência do Solo, 2008
O parâmetro S representa o valor da inclinação da curva de retenção de água no seu ponto de inflexão. Um aumento nos valores de S indica uma ampla distribuição de tamanho de poros, condizente com condições estruturais que estabelecem um adequado ...

Nanoparticle‐Coated X2CrNiMo17‐12‐2 Powder for Additive Manufacturing – Part I: Surface, Flowability, and Optical Properties of SiC, Si, and Si3N4 Coated Metal Powders

open access: yesAdvanced Engineering Materials, Volume 27, Issue 14, July 2025.
Herein, silicon‐based nanoparticle coatings on X2CrNiMo17‐12‐2 metal powder are presented. The coating process scale, process parameters, nanoparticle size (65–200 nm) as well as the coating amount are discussed regarding powder properties. The surface roughness affects the flowability, while reflectance depends on the coating material and surface ...
