Spatio-temporal rainfall variability in the Amazon basin countries (Brazil, Peru, Bolivia, Colombia, and Ecuador)
(Wiley Online Library, 2009-09)
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 includes data from Bolivia, Peru, ...

A comparative analysis of TRMM-rain gauge data merging techniques at the daily time scale for distributed rainfall-runoff modeling applications
(American Meteorological Society, 2015-01)
This study compares two nonparametric rainfall data merging methods-the mean bias correction and double-kernel smoothing-with two geostatistical methods-kriging with external drift and Bayesian combination-for optimizing ...

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 ...

Basin-scale analysis of rainfall and runoff in Peru (1969–2004): Pacific, Titicaca and Amazonas drainages
(Taylor and Francis Ltd., 2012-06)
According to the Peruvian agricultural ministry, the Pacific watersheds where the great cities and intense farming are located only benefit from 1% of the available freshwater in Peru. Hence a thorough knowledge of the ...

Projected increases in the annual flood pulse of the Western Amazon
(Institute of Physics Publishing, 2016-01)
The impact of a changing climate on the Amazon basin is a subject of intensive research because of its rich biodiversity and the significant role of rainforests in carbon cycling. Climate change has also a direct hydrological ...

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 ...

Assessment of climate change impacts on the hydrology of the Peruvian Amazon-Andes basin
(Wiley-Blackwell, 2011-11)
In this article, we propose an investigation of the modifications of the hydrological response of two Peruvian Amazonas-Andes basins in relationship with the modifications of the precipitation and evapotranspiration rates ...

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 ...

The integration of field measurements and satellite observations to determine river solid loads in poorly monitored basins
(IRD France Nord, 2012-06)
The use of satellite imagery to assess river sediment discharge is discussed in the context of poorly monitored basins. For more than three decades, the Peruvian hydrological service SENAMHI has been maintaining several ...

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 ...
