A comparative analysis of TRMM-rain gauge data merging techniques at the daily time scale for distributed rainfall-runoff modeling applications

Nerini, D.; Zulkafli, Z.; Wang, L.-P.; Onof, C.; Buytaert, W.; Lavado-Casimiro, W.; Guyot, J.L. (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 ...

Amazon River dissolved load: temporal dynamics and annual budget from the Andes to the ocean

Moquet, J.S.; Guyot, J.L.; Crave, A.; Viers, J.; Filizola, N.; Martinez, J.-M.; Oliveira, T.C.; Sánchez, L.S.H.; Lagane, C.; Lavado-Casimiro, W.; Noriega, L.; Pombosa, R. (Springer Verlag, 2016-06)

The aim of the present study is to estimate the export fluxes of major dissolved species at the scale of the Amazon basin, to identify the main parameters controlling their spatial distribution and to identify the role of ...

Basin-scale analysis of rainfall and runoff in Peru (1969–2004): Pacific, Titicaca and Amazonas drainages

Lavado-Casimiro, W.; Ronchail, J.; Labat, D.; Espinoza, J.C.; Guyot, J.L. (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

Zulkafli, Z.; Buytaert, W.; Manz, B.; Rosas, C.V.; Willems, P.; Lavado-Casimiro, W.; Guyot, J.L.; Santini, W. (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 ...

Spatio-temporal rainfall variability in the Amazon basin countries (Brazil, Peru, Bolivia, Colombia, and Ecuador)

Villar, J.C.E.; Ronchail, J.; Guyot, J.L.; Cochonneau, G.; Naziano, F.; Lavado-Casimiro, W.; De Oliveira, E.; Pombosa, R.; Vauchel, P. (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, ...

Assessment of climate change impacts on the hydrology of the Peruvian Amazon-Andes basin

Lavado-Casimiro, W.; Labat, D.; Guyot, J.L.; Ardoin-Bardin, Sandra (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 ...

From drought to flooding: understanding the abrupt 2010-11 hydrological annual cycle in the Amazonas River and tributaries

Espinoza, J.C.; Ronchail, Josyane; Guyot, J.L.; Junquas, Clémentine; Guillaume, Drapeau; Martinez, Jean Michel; William, Santini; Philippe, Vauchel; Lavado-Casimiro, W.; Ordoñez, Julio; Espinoza-Villar, R. (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 ...

Cl and Na Fluxes in an Andean Foreland Basin of the Peruvian Amazon: An Anthropogenic Impact Evidence

Moquet, Jean-Sébastien; Maurice, Laurence; Crave, Alain; Viers, Jérôme; Arevalo, Nore; Lagane, C.; Lavado-Casimiro, W.; Guyot, J.L. (Springer, 2014-09-14)

The dissolved load of the Amazon River is generally considered to be lowlyimpacted by anthropogenic activities. In this work, based on the chemical and hydrologicaldatabase of the Environmental Research Observatory—HYBAM ...
