Abstract Wetlands provide valuable ecosystem services and play a central role in global carbon cycling. Changes rainfall the flood-pulse are likely to disrupt processes that maintain these landscapes; further, landscape modification may dramatically alter wetlands promote terrestrialization. The Pantanal, South America, is world’s largest wetland due flooding along Upper Paraguay River. Predicting how water resources Pantanal change problematic complex drainage network, resulting...
Abstract The Pantanal is the world's largest tropical wetland and a biodiversity hotspot, yet its response to Quaternary environmental change unclear. To address this problem, sediment cores from shallow lakes connected Upper Paraguay River (PR) were analyzed radiocarbon dated track changes in sedimentary environments. Stratal relations, detrital particle size, multiple biogeochemical indicators, sponge spicules suggest fluctuating lake-level lowstand conditions between ~ 11,000 5300 cal yr...
Abstract: The Chaco foreland is well known for its spectacular fluvial megafans, and this basin frequently serves as a modern analog studies that use the geological record to investigate tectonic processes in convergent orogenic systems. Yet little sedimentary data has been recovered from southern Chaco, particularly at latitude of northern Argentina, which limits both utility an our understanding Andean megafan development subtropics. amenable time-slice systems analysis, environmental...
Abstract Nhecolândia is a fossil lobe of the Taquari River megafan and prominent geomorphic subunit Pantanal wetlands because presence >10,000 small lakes. We investigated stratigraphic records three saline lakes from to explore their potential as Quaternary hydroclimate archives. Radiocarbon data indicate that accumulation at two was approximately continuous in late Holocene, chemostratigraphic variability suggests sensitivity environmental change with multicentennial resolution. A basal...
The Pantanal wetland is a mosaic of landscapes that brings together rich biodiversity with the valuable activities fishing, tourism and ranching. Human occupation land use in headwaters have intensified rate channel avulsions lower reaches largest megafan on Taquari River. This study evaluates long-term changes active depositional lobe from perspective local communities pantaneiros. Maps derived multiple decades multispectral Landsat data proven useful for studying cover through relationship...
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 aim of this study is to characterize the channel pattern Paraguay River between Cabacal and Pelado Hill in Caceres area (MT). To do so, analyses on fluvial hydrodynamics, morphology floodplain, typology bars, were carried out. research was developed through use orbital images, hydrologic data field works. morphologic analysis, floodplain landscapes, bars styles showed that such presents two segments with different patterns. upper segment has meandering braided characteristics lower...
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....
Aquatic macrophytes are important components of wetland ecosystems, and studying them contributes to a better understanding ecological succession in the Pantanal. The function history floating on shores Lake Uberaba, located Paraguay River floodplain, were examined. A multitemporal analysis Landsat satellite images years 1984-2015 was conducted. For analysis, land cover map generated with three classes: water, aquatic macrophytes, surroundings (undefined vegetation). results revealed ~21.4%...
