Discharge simulation in the sub-basins of the Amazon using ORCHIDEE forced by new datasets
(Copernicus GmbH, 2012-03)
The aim of this study is to evaluate the ability of the ORCHIDEE land surface model to simulate streamflows over each sub-basin of the Amazon River basin. For this purpose, simulations are performed with a routing module ...

The Major Floods in the Amazonas River and Tributaries (Western Amazon Basin) during the 1970-2012 Period: A Focus on the 2012 Flood
(American Meteorological Society, 2013)
In this work, the authors analyze the origin of the extreme floods in the Peruvian Amazonas River during the 1970-2012 period, focusing on the recent April 2012 flooding (55400m3 s-1). Several hydrological variables, such ...

Sediment budget in the Ucayali River basin, an Andean tributary of the Amazon River
(Copernicus GmbH, 2014-01)
Formation of mountain ranges results from complex coupling between lithospheric deformation, mechanisms linked to subduction and surface processes: weathering, erosion, and climate. Today, erosion of the eastern Andean ...

Trends in rainfall and temperature in the Peruvian Amazon-Andes basin over the last 40years (1965-2007)
(John Wiley & Sons, Inc., 2013-09)
The hydroclimatology of the Peruvian Amazon-Andes basin (PAB) which surface corresponding to 7% of the Amazon basin is still poorly documented. We propose here an extended and original analysis of the temporal evolution ...

Control of seasonal and inter-annual rainfall distribution on the Strontium-Neodymium isotopic compositions of suspended particulate matter and implications for tracing ENSO events in the Pacific coast (Tumbes basin, Peru)
(Institut de recherche pour le développement-IRD, 2020-01)
The geochemistry of riverine sediments exported to the oceans is important for paleo-hydro-climatic reconstruction. However, climate reconstruction requires a good understanding of the relationship between geochemistry and ...
Variabilidad espacio-temporal de las lluvias en la cuenca amazónica y su relación con la variabilidad hidrológica regional. Un enfoque particular sobre la región andina
(Servicio Nacional de Meteorología e Hidrología del Perú, 2010)
La variabilidad de las precipitaciones en la cuenca amazónica (CA) es analizada para el período 1964-2003. Este análisis está basado en 756 estaciones pluviométricas distribuidas en todos los países de la cuenca incluyendo ...

From drought to flooding: understanding the abrupt 2010-11 hydrological annual cycle in the Amazonas River and tributaries
(Institute of Physics Publishing, 2012-01)
In this work we document and analyze the hydrological annual cycles characterized by a rapid transition between low and high flows in the Amazonas River (Peruvian Amazon) and we show how these events, which may impact ...
