Genesis and sedimentary record of blind channel and islands of the anabranching river: An evolution model
(2018-02-01)
Blind channel (BC) is a fluvial feature formed by attachment of a lateral sand bar to an island or riverbank. It consists of a 10- to 20-m wide and hundreds to thousands meters long channel, parallel to the island or bank, ...
Origin, evolution, and sedimentary records of islands in large anabranching tropical rivers: The case of the Upper Paraná River, Brazil
(2020-06-01)
Anabranching patterns are characteristic of the largest rivers in the world. We have chosen to study the Paraná River because of its worldwide importance among the great rivers and the large database available from over ...
Why do large rivers tend to form multichannel? A field study in the Upper Paraná RiverPor que grandes rios tendem à canalização múltipla? Um estudo de campo no rio Paraná Superior
(2021-01-01)
Anastomosed rivers include a diverse group of fluvial forms with multiple and interconnected alluvial channels. They occur in a wide range of climates and reliefs and constitute the typical pattern of the mega rivers (Qm ...
COMPARTMENTALIZATION AND GEOMORPHOLOGICAL EVOLUTION OF THE CUIABA RIVER FLOODPLAIN, MATO GROSSO, PANTANAL
(Uniao Geomorfologia Brasileira, 2019-01-01)
The Cuiaba River watershed, located in the state of Mato Grosso, drains an area of approximately 36,000 km(2). When it enters the Pantanal area in Mato Grosso, the Cuiaba river starts depositing the sediments transported ...
Phytoliths indicate environmental changes correlated with facies analysis in a paleo island-lake, Upper Paraná River, Brazil
(2020-04-01)
Phytolith analysis has become a useful tool for paleoenvironmental studies. Phytoliths are produced by plants and are composed of biogenic silica, giving them higher resistance to diagenetic and oxidation processes that ...

Sponge spicules as indicators of paleoenvironmental changes in island deposits – Upper Paraná River, Brazil
(2019-12-15)
Sediments of fluvial islands are important records for paleoenvironmental and paleoclimatic reconstruction, especially those related to the late Pleistocene and Holocene. The Upper Paraná River (UPR) has numerous ...
Turbidity and dissolved organic matter as significant predictors of spatio-temporal dynamics of phosphorus in a large river-floodplain system
(John Wiley & Sons Ltd, 2018-09)
Phosphorus (P) inputs are increasing in river‐floodplain systems, but the factors whichinfluence the dynamics of this nutrient are not clear. To assess P dynamics in this kindof river, the main channel of the Middle Paraná ...
