Spatiotemporal variations in channel changes caused by cumulative factors in a meandering river: The lower Peixe River, Brazil
(Elsevier B.V., 2016-11-15)
Channel changes in meandering rivers naturally exhibit complex behaviour, and understanding the river dynamics can be challenging in environments also subject to cumulative human impacts. Planform changes were analysed on ...
Geomorphologic, circulation and dynamic analysis in a meandering tidal channel, Bahía Blanca Estuary
(Universidade de Vigo, 2003-12)
A meander of La Lista tidal channel (Bahia Blanca Estuary, Argentina) was selected in order to study the relationship between the geoforms that control the meandering channel evolution (mainly tidal flats and marshes) arid ...
Temporal and spatial adjustments of channel migration and planform geometry: responses to ENSO driven climate anomalies on the tropical freely-meandering Aguapeí River, São Paulo, Brazil
(2018-06-30)
Two reaches of Aguapeí River, a left-bank tributary of the Paraná River in western São Paulo state, Brazil, were studied with the objective of assessing the role of bend curvature on channel migration in this wet-tropical ...
Meandering rivers in modern desert basins: Implications for channel planform controls and prevegetation rivers
(2019-05-01)
The influence of biotic processes in controlling the development of meandering channels in fluvial systems is controversial. The majority of the depositional history of the Earth's continents was devoid of significant ...
FLUVIAL FORMS AND PROCESSES ASSOCIATED TO MEANDERING CHANNEL PATTERN: THE LOWER PEIXE RIVER, SP
(Uniao Geomorfologia Brasileira, 2016-07-01)
The aim of this study is to identify and characterize forms and processes associated to the meandering channel pattern in the alluvial valley of the Lower Peixe River, Sao Paulo State, Brazil. Geomorphological interpretations ...
Heterolithic meandering-channel deposits from the Neoproterozoic of NW Scotland: Implications for palaeogeographic reconstructions of Precambrian sedimentary environments
(2016-01-01)
Pre-Silurian fine-grained meandering river deposits are apparently rare in the rock record. Most modern-day river dynamics are influenced by vegetation through bank stabilization, fine-grained sediment production and ...
Caracterização geométrica de um sistema fluvial, formação Ttaquaquecetuba, Terciário da Bacia de São Paulo
(2006-12-01)
The objective of this study is the geometric characterization of a fluvial system, exemplified by the Itaquaquecetuba Formation. The studied area is a quarry located in Itaquaquecetuba, distant 35 km from the city of São ...
Meander Statistics Toolbox (MStaT): a toolbox for geometry characterization of bends in large meandering channels
(Elsevier, 2021-06)
This contribution presents MStaT, a wavelet-based open-source software developed to provide a detailed characterization of large meandering river morphodynamics. MStaT integrates three independent modules: (i) meandering ...
Hydraulic resistance in mixed bedrock-alluvial meandering channels
(International Association for Hydro-Environment Engineering and Research, 2020-05-10)
We present an experimental analysis of hydraulic roughness variations due to changes in alluvial cover in a mixed bedrock-alluvial meandering channel with larger bedrock roughness than alluvial roughness. Three sets of ...
