A Revista Brasileira de Geomorfologia (RBGeomorfologia), e-ISSN 2236-5664, foi criada em 2000, com foco em pesquisas relacionadas à gênese, processos, evolução e formas de relevo. Compreende a utilização e integração de dados laboratoriais, registros geológicos, indicadores morfométricos, ferramentas de geotecnologias e modelagem aplicadas à geomorfologia. A revista aborda os impactos das mudanças ambientais na superfície terrestre, considerando fatores naturais e antrópicos, contribuindo…

Coastal erosion is a relevant concern along the semi-arid coast of Northeastern Brazil, where tide-modified mixed siliciclastic–carbonate beaches exhibit seasonal variability and increasing anthropogenic pressure. This study aims to analyze the seasonal sedimentary dynamics of Peroba and Picos beaches, located in Icapuí, Ceará. Sediment samples were collected during four field campaigns, in March,…
The Pantanal wetland, located in the Upper Paraguay River Basin, is the world's largest tropical wetland and a key region for understanding fluvial system responses to Late Quaternary climatic changes. This study investigates the geomorphological evolution of the Paraguay-Corumbá Fluvial Plain (PCFP; approximately 18.3°S to 19.4°S and 57.0°W to 57.8°W) using remote sensing, sedimentological…
This study investigates planation surfaces and the dynamics of river divides in Northeast Brazil, with a focus on the Chapada do Araripe region. The research integrates morphometric metrics and regional geological interpretation to understand the processes that shape the evolution of the relief through the migration of divides and the interposition of planation surfaces. Geomorphometric metrics…
Gullies in urban environments pose challenges to urban land-use planning due to their rapid development and the impact they cause on infrastructure and the physical environment. This study aimed at monitoring four gullies located in Colônia Antônio Aleixo watershed, in Manaus, Brazil, to analyze their morphometric characteristics and to estimate associated erosion rates. The study was based on…
The analysis of morphometric parameters has been widely employed to assess flood susceptibility; however, at broader scales, it tends to homogenize and generalize results, concealing relevant local differences. This study aims to investigate flood susceptibility using fifteen morphometric parameters in a GIS environment, at scales ranging from basins and sub-basins up to the sixth order, located…
Forest fires, intensified by human activities, are transformed into environmental disasters and affect biomes that are not naturally adapted to fire, such as the Caatinga. With the advent of climate change and the increasing number of fires, it becomes necessary to understand their impact on surface environmental dynamics, including sedimentological processes. One way to analyze these changes is…
The geomorphological mapping of the state of Mato Grosso is presented, integrating theoretical and methodological perspectives of geomorphometry, the history of local geomorphological cartography and discussions within the scope of the SBCR. A hierarchical classification was established in four taxons with morphological emphasis (macro landforms, morphostructures, landform units and landform…
On Thursday, February 8th, 2024, a subaqueous slope failure occurred adjacent to the sand spit terminus at Puntarenitas, Puerto Jiménez, Costa Rica, whereby sediments were mobilized from a nearshore area encompassing approximately 410 m² of beach front. Investigation procedures included salinity, temperature, and density profiling at multiple stations, complemented by underwater videography.…
The uprush and backwash of a wave ( swash climate ) at the beach face, as well as the duration of this process, depend not only on wave characteristics such as height and period, but also on the beach-face slope, which in turn is partially conditioned by the sediment grain size. As a general trend, the coarser the grain size, the steeper the slope, and faster the uprush and backwash cycle (swash…
Landslides represent one of the major socio-environmental risks worldwide, with socio-economic impacts intensified by unequal urbanization and the increasing frequency of extreme events associated with climate change. In this context, monitoring and early warning systems based on low-cost sensors emerge as a strategic alternative to expand the coverage and accessibility of these technologies,…
