Regional maximum rainfall analysis using L-moments at the Titicaca Lake drainage, Peru
(Springer-Verlag Wien, 2017-08)
The present study investigates the application of the index flood L-moments-based regional frequency analysis procedure (RFA-LM) to the annual maximum 24-h rainfall (AM) of 33 rainfall gauge stations (RGs) to estimate ...

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

The freezing level in the tropical Andes, Peru: An indicator for present and future glacier extents
(Wiley-Blackwell, 2017-10)
Along with air temperatures, the freezing level height (FLH) has risen over the last decades. The mass balance of tropical glaciers in Peru is highly sensitive to a rise in the FLH, mainly due to a decrease in accumulation ...

Regionalization of rainfall over the Peruvian Pacific slope and coast
(John Wiley and Sons Ltd, 2017-01)
Documenting the heterogeneity of rainfall regimes is a prerequisite for water resources management, mitigation of risks associated to extremes weather events and for impact studies. In this paper, we present a method for ...

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 ...

Hydrological and depositional processes associated with recent glacier recession in Yanamarey catchment, Cordillera Blanca (Peru)
(Elsevier B.V., 2017-02)
In this study, we investigate changes in the glaciated surface and the formation of lakes in the headwater of the Querococha watershed in Cordillera Blanca (Peru) using 24 Landsat images from 1975 to 2014. Information of ...
Accuracy assessment of SRTM v4 and ASTER GDEM v2 over the Altiplano watershed using ICESat/GLAS data
(Taylor and Francis Ltd., 2015-01)
The new Global Digital Elevation Model (GDEM v2) has been available since 17 October 2011. With a resolution of approximately 30 m, this model should provide more accurate information than the latest version of Shuttle ...

Impacts of satellite-based precipitation datasets on rainfall-runoff modeling of the Western Amazon basin of Peru and Ecuador
(Elsevier, 2015-09)
Satellites are an alternative source of rainfall data used as input to hydrological models in poorly gauged or ungauged regions. They are also useful in regions with highly heterogeneous precipitation, such as the tropical ...

A critical assessment of the JULES land surface model hydrology for humid tropical environments
(Hydrology and Earth System Sciences (HESS), 2013-01)
Global land surface models (LSMs) such as the Joint UK Land Environment Simulator (JULES) are originally developed to provide surface boundary conditions for climate models. They are increasingly used for hydrological ...
