The recent interest in El Niño Phenomenon stems from: 1) our better understanding of the physical processes involved, which in turn has made possible its early prediction, 2) the realization that it affects the climate at a global scale, and 3) its unusual recent intense episodes and their higher ...

The Mantaro River Basin (34550,08 Km2) is located on the eastern slope of the central Peruvian Andes, between the coordinates 10º34’30’’S- 13º35’30’’S/ 73º55’00’’W- 76º40’30”W. This is a very complex basin due to its geomorphology, with almost 85% of its territory located above 3000 masl. This basin ...

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, Ecuador, and Colombia. In particular, the recent availability of rainfall data ...

The Andes as mountain regions worldwide, provide fundamental resources, not only for the local population. Due to the topographic characteristics, the potential for natural hazards is higher than elsewhere. In these areas, assessments of climate change impacts and the development of adequate adaptation ...

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 the Amazonian hydrological system. This study therefore uses a new data set including daily discharge in 18 sub-basins ...
