This study aims at providing an overview of the socioeconomic consequences that debris-flow events have caused in Brazil, positioning country international scenario and identifying areas where targeted actions are necessary. The analysis is conducted by calculating mortality rate (MR) using so-called F-N plots (frequency N or more fatalities vs. number fatalities), based on a compilation debris-flow-related disasters from 1920 to 2021. In total, 45 were documented considered period,...
Abstract Debris flows represent great hazard to humans due their high destructive power. Understanding hydrogeomorphic dynamics is fundamental in assessment studies, especially subtropical and tropical regions where debris have scarcely been studied when compared other mass-wasting processes. Thus, this study aims at systematically analyzing the meteorological geomorphological factors that characterize a landslide-triggered flow Pedra Branca catchment (Serra do Mar, Brazil), quantify flow’s...
This work aims to evaluate the potential for debris-flow triggering from Santo Antônio hydrographic basin, located in Serra do Mar region on North Coast of State São Paulo, Brazil, based physiographic attributes, rainfall data, and morphometric parameters. For this purpose, basin techniques were applied, assessing vulnerability debris flow geomorphological, geological, climatic, anthropic aspects, parameters relevant these processes watersheds calculated. Seven units identified, which...
The geo-environmental zoning represents an important strategy in the territorial management. However, it requires a logical and structured procedure. Therefore, approach using physiographic compartmentalization is proposed applied as case study region covered by topographic maps of São José dos Campos Jacareí, Brazil. This has great geological geomorphological peculiarities, beyond being place with large human interventions because its quickly economic growth. methodology based on...
Vegetation Indices (VIs) provide spatial information on the vegetation state, which has been associated with landslide propensity. To evaluate how VIs indicate propensity, current study analyzed nine different IVs to identify categories of states in hydrographic basin Pedra Branca before and after event. The were obtained using Sentinel-2A (2016) Sentinel-2B (2018) images. All tested by cross-table analysis regard ability calculated area for scars, also compared NDVI reference error matrix...
Physiographic compartmentalisation emerges as an important instrument in urban planning and risk assessment of mountainous areas, identifying regions where natural erosive processes are more likely to occur based on landform features. The Serra do Mar escarpments naturally prone landslide occurrences, due its characteristics climate, studies that correlate triggering (rainfall) with controlling (landform) factors fundamental the development programmes. In this context, study aims assess...
There are several procedures of spatialization and individualization physical environmental units, such as the techniques remote sensing geoprocessing. The physiographic compartmentation can be performed by systematic photointerpretation processes satellite images, trough analysis drainage network's properties, from homogeneity similarities landscape units. advantage applying this technique in planning is generation a single cartographic product sectioned into which summarize characteristics...
Abstract Debris flows are rapid downslope, gravity-driven movements of highly viscous, dense and concentrated/hyperconcentrated fluid materials. In Brazil, the most susceptible area to this type mass movement comprises oriented foothills Serra do Mar. Several numerical modeling approaches have been created measure, identify, predict monitor debris flow. Rapid simulation (RAMMS) is a single-phase model that describes flow frictional behavior using Voellmy relation. work, RAMMS method applied...
Os estudos geoambientais, embora recentes, ganham cada vez mais espaço como uma importante ferramenta do planejamento ambiental. O planejador primeiro compartimenta o espaço, buscando entender melhor parte que compõe ambiente, e depois integra para suas interações otimizá-las. A pesquisa teve principal objetivo elaborar mapeamento geoambiental município de Casa Branca, São Paulo, na escala 1:50.000, considerando critérios fisiográficos, geológico-geotécnicos uso ocupação da terra, incluindo...
O presente artigo tem como objetivo apresentar os estudos desenvolvidos para elaboração de mapeamento geoambiental por meio do uso da compartimentação fisiográfica e abordagem multitemática, envolvendo a correlação das unidades fisiográficas, o ocupação terra, presença áreas preservação permanente carta chuvas intensas médias. Foram estabelecidos municípios Espírito Santo Pinhal Antônio Jardim (SP) área estudo, que se localizam no limite entre Bacia Sedimentar Paraná embasamento cristalino...
A área de estudo localiza-se nos municípios Caraguatatuba e São Sebastião, litoral norte do Estado Paulo, apresenta alto potencial para ocorrência escorregamentos, pois está localizada no domínio da Serra Mar, com relevo escarpado associado ao índice pluviométrico região. Desse modo, análises voltadas reconhecimento maior compreensão dos fatores condicionantes fenômenos naturais, como os são grande importância que possam ser evitados danos riscos a partir previsão tais fenômenos. O objetivo...

Este artigo apresenta as informações obtidas pela compartimentação fisiográfica da região abrangida pelas folhas topográficas São José dos Campos e Jacareí (SP), em escala 1:50.000, com o uso de técnicas sensoriamento remoto fotointerpretação empregadas na banda 4 imagem orbital Landsat-5. No total, foram delineadas 19 unidades fisiográficas região, distribuídas ao longo do Embasamento Cristalino Bacia Sedimentar Taubaté. Os resultados gerados servem para nortear considerações referentes...
The current case study focuses on oil the Environmental Sensitivity Index (ESI) mapping of Guanabara Bay, Rio de Janeiro State, Brazil—a region at risk from petroleum sector pollution. By 981.5 km coastline and classifying it in 10 sensitivity indices, we integrated biotic resources, socioeconomic factors, geoenvironmental diversity into a geodatabase. Results reveal high bay, with approximately 89% shoreline scoring ESI 8 10, representing estuarine solid substrate habitats, respectively....
