Classificação de usos da terra por análise discriminante multigrupos
Filgueiras, Roberto; ; Landim, Paulo Milton Barbosa ; Zimback, Célia Regina Lopes (Geociencias, 2016) [Artigo]
The discrimination of different land uses based on satellite data is a widely used procedure, mainly because of processing speed and low cost of realization, depending on the sensor used. The process becomes complex when ... -
Paleosols record dry and humid paleoenvironments during the Upper Pleistocene in the Brazilian Pantanal
; Mescolotti, Patricia Colombo; ; ; Assine, Mario Luis (Catena, 2022) [Artigo]
Information on Quaternary landscapes and paleoenvironmental changes in the interior of Brazil are scarce. One of such areas, particularly sensitive to these variations, is the modern tropical Pantanal wetland, whose alluvial ... -
Delineation of necroleachate pathways using electrical resistivity tomography (ERT): Case study on a cemetery in Brazil
Netto, Leonides Guireli; Filho, Walter Malagutti ; Moreira, César Augusto ; ; (Environmental Challenges, 2021) [Artigo]
Cemeteries can be considered as potential sources of soil and groundwater contamination in burial sites where there is no collection and treatment system for necroleachate, an effluent rich in organic matter and inorganic ... -
Organic fades analysis of romualdo formation (santana group, lower cretaceous from araripe basin): Characterization of sedimentary organic matter andpaleoenvironmental interpretation
; ; ; Assine, Mario Luis (Geologia USP - Serie Cientifica, 2018) [Artigo]
The paleoenvironmental reconstruction of the Santana Group (Late Aptian-Early Albian) is a matter of controversy, es pecially concerning the marine influence on sedimentation. In this context, palynofacies analysis can be ... -
A new approach to improve the accuracy of DGT (Diffusive Gradients in Thin-films) measurements in monitoring wells
Santos, Cristiane Aily; Gemeiner, Hendryk ; Menegário, Amauri Antonio ; ; Zanatta, Melina Borges Teixeira ; Chang, Hung Kiang (Talanta, 2022) [Artigo]
The Diffusive Gradients in Thin-films (DGT) technique represents an ideal tool for monitoring water quality of inorganic species in systems with a high flow such as rivers, streams, lakes and seas. However, in low-flow ... -
An alternative approach to designing hydrogeological conceptual models in cases of scarce field data
