Interannual rainfall variability in the Amazon Basin and sea-surface temperatures in the Equatorial pacific and the Tropical Atlantic oceans
Rainfall variability in the Amazon basin is studied in relation to sea-surface temperatures (SSTs) in the equatorial Pacific and the northern and southern tropical Atlantic during the 1977–99 period,Expand
Exportation of organic carbon from the Amazon River and its main tributaries
As part of a joint Brazilian–French project, entitled ‘Hydrology and Geochemistry of the Amazon Basin’, we carried out a seven-year study (1994–2000) on the distribution, behaviour and flux ofExpand
Episodic sediment accumulation on Amazonian flood plains influenced by El Niño/Southern Oscillation
It is concluded that transient processes driven by the El Niño/Southern Oscillation cycle control the formation of the Bolivian flood plains and modulate downstream delivery of sediments as well as associated carbon, nutrients and pollutants to the Amazon main stem. Expand
Spatio-temporal rainfall variability in the Amazon basin countries (Brazil, Peru, Bolivia, Colombia, and Ecuador)
Rainfall variability in the Amazon basin (AB) is analysed for the 1964–2003 period. It is based on 756 pluviometric stations distributed throughout the AB countries. For the first time it includesExpand
Evidence for global runoff increase related to climate warming
Ongoing global climatic change initiated by the anthropogenic release of carbon dioxide is a matter of intense debate. We focus both on the impact of these climatic changes on the global hydrologicalExpand
Recent advances in wavelet analyses: Part 2—Amazon, Parana, Orinoco and Congo discharges time scale variability
This paper is devoted to illustrating new wavelet analysis methods in the field of hydrology. New wavelet indicators are applied to long-term hydrological and climatologic proxies. They are firstExpand
Geomorphic Controls on Andean Denudation Rates
To predict erosion rates throughout the Andes, we conducted a multiple regression analysis of the sediment discharge from 47 drainage basins in the Bolivian Andes and various topographic,Expand
Oxygen isotopes in tree rings are a good proxy for Amazon precipitation and El Niño-Southern Oscillation variability
A century-long record from northern Bolivia shows that tree rings preserve the signal of oxygen isotope ratios in annual rings in tropical cedar, a unique proxy for the reconstruction of variation in precipitation over the Amazon. Expand
Temporal dynamics of water and sediment exchanges between the Curuaí floodplain and the Amazon River, Brazil
The fluvial transport and storage of sediments within channel floodplain systems can act as important sinks of sediments. In this study, we document the role of an Amazonian floodplain (Curuai) forExpand
Contrasting regional discharge evolutions in the Amazon basin (1974–2004)
Summary Former hydrological studies in the Amazon Basin generally describe annual discharge variability on the main stem. However, the downstream Amazon River only represents the mean state of theExpand
