ABSTRACT The Pantanal Basin is an active sedimentary basin in central-west Brazil that consists of a complex alluvial systems tract characterized by the interaction between different river developed one largest wetlands world. Paraguay River trunk system drains water and part sediment load received from areas outside basin. Depositional styles vary considerably along profiles throughout basin, with development entrenched meandering belts, anastomosing reaches, floodplain ponds. Paleodrainage...
The state of Amapá within the Amazon biome has a high complexity ecosystems formed by forests, savannas, seasonally flooded vegetation, mangroves, and different land uses. present research aimed to map vegetation from phenological behavior Sentinel-1 time series, which advantage not having atmospheric interference cloud cover. Furthermore, study compared three sets images (vertical–vertical co-polarization (VV) only, vertical–horizontal cross-polarization (VH) both VV VH) classifiers based...
The Nhecolândia region, located in the southern portion of Pantanal wetland area, is a unique lacustrine system where tens thousands saline-alkaline and freshwater lakes ponds coexist close proximity. These are suspected to be strong source greenhouse gases (GHGs) atmosphere, water pH being one key factors controlling biogeochemical functioning and, consequently, production emission GHGs these lakes. Here, we present new field-validated classification using values estimated based on...
Tropical dry forests are a forest ecosystem notably marked by climatic seasonality and predominance of tree species that present deciduousness during the season great perenniality wet season. These environments home to rich diversity fauna flora, playing crucial role in quality life millions people providing essential services. Due their occurrence fertile soils, there have been increasing records anthropic pressures on remnants for conversion agriculture. For this reason, demand...
The Pantanal wetland is a complex landscape with distinct hydrogeomorphic compartments, singular and hydrosedimentary processes. Examining these processes draws great interest in understanding dynamics for both the management of system geological record predicted by facies models. Hydrosedimentary data remain scarce, spite government efforts to improve increase collection Upper Paraguay Basin. This study aims enhance active trunk-river Corumbá reach. surveys were accomplished main channel...
O Paraguai é o rio-tronco do trato de sistemas deposicionais Pantanal. Com base em dados sensores remotos e verificação campo, foi realizado mapeamento geomorfológico da planície rio no trecho entre as confluências dos rios Cuiabá Miranda, onde foram reconhecidas formas atuais antigas. A análise das associações permitiu estabelecer proposta evolução geomorfológica para a área, mas os eventos carecem ainda datação precisa por métodos geocronológicos. Uma rede drenagem abandonada multicanais...
The Pantanal is one of the world’s largest freshwater wetlands. spatial and temporal variability flooded areas a key factor for preserving managing flora fauna this biodiversity hotspot, thus, its dynamic crucial to maintain ecosystem services. However, existing inventories with high resolution are scarce or do not represent continuous time series considering entire wetland. In study, were derived from Landsat Resourcesat satellite imagery years 2000 2020 through big data analytical tools....
Global measurements of reservoir water levels are crucial for understanding Earth’s hydrological dynamics, especially in the context global industrialization and climate change. Although radar altimetry has been used to measure level some reservoirs with high accuracy, it is not yet feasible unless body sufficiently large or directly located at satellite’s nadir. This study proposes a gauging method applicable wide range using Sentinel–1 Synthetic Aperture Radar data digital elevation model...
Rivers are immensely important to human activities such as water supply, navigation, energy generation, and agriculture. They also an morphodynamic agent of erosion, transport deposition. Their capacity sediment depends on their hydraulic characteristics can be predicted by mathematical models. Several models used compute bed-load transport. Each one is appropriately better for certain conditions. In this paper, we present application built in Microsoft Excel the rivers based Van Rijn model....
O rio Miranda é um importante afluente do Paraguai e tem grande parte de seu curso na planície Pantanal. sinuosidade média a alta, sendo tipo meandrante maior percurso em domínio aluvial. Com base nos padrões canal da planície, três segmentos fluviais com diferentes estilos foram caracterizados descritos. Ainda domínios planalto, o forma cinturão meandros numa agradacional, que está confinada vale no embasamento cristalino. deixa correr num ao adentrar Pantanal, para formar cordão composto...
Abstract Wetlands are permanently or seasonally flooded areas which support countless species of plants and animals. The Pantanal, in central‐west Brazil is one the largest freshwater wetlands world covering an area ~150 000 km 2 . relationships between geomorphology, hydrology, sedimentation, vegetation cover critical for understanding how landscape constrains dynamics wetlands. We provide a detailed study geomorphology surface hydrology Negro River Interfan System (NRIS), southern by...
Estudos referentes à fisiografia e ao funcionamento de sistemas fluviais têm aumentado em todo mundo o mesmo se aplica àqueles realizados nos grandes brasileiros. Inúmeras são as dificuldades para estudo planícies destacando-se acesso a locomoção. A utilização produtos sensoriamento remoto geotecnologias ótimas alternativas áreas difícil acesso. Com crescente popularização das geotecnologias, os modelos digitais elevação (MDEs) tornaram-se mais comuns análise extração informações...
A ocorrência de escorregamentos translacionais rasos no litoral paulista é parte integrante da evolução natural das encostas, que se intensifica sob condições clima tropical em uma morfologia serras com desníveis torno 700m. Sob precipitações intensas, mesmo sem a interferência direta do homem, os movimentos massa ocorrem forma isolada ou generalizada. Devido à presença um grande histórico massa, tomou-se como área estudo Serra Mar Paulista localizada município Cubatão-SP. Esse trabalho teve...
