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 regionalization of rainfall over the Peruvian Pacific slope and coast, which is the main economic zone of the country and concent...
Article
In a context of water scarcity in Peruvian Pacific catchments as a crucial issue for Peru, added to the paucity of data availability, we propose a methodology which provides new perspectives for freshwater availability estimation as a base reference for unimpaired conditions. Under those considerations, a regional discharge of 709 m³/s to the Pacif...

Quantification of the surface water offer is crucial for its management. In Peru, the low spatial density of hydrometric stations makes this task challenging. This work aims to evaluate the hydrological performance of a monthly water balance model in Peru using precipitation and evapotranspiration data from the high-resolution meteorological PISCO...
Article
Integrated approaches are needed to understand and respond to changes in tropical mountain ecosystems and communities brought about by receding glaciers and changes in land use. Read the full article here: https://eos.org/features/adapting-to-receding-glaciers-in-the-tropical-andes
Conference Paper
Full-text available
Hydrological assessment of the stormwater runoff is a relevant tool to support sustainable drainage planning decisions. In this research, we address the pluvial floods in the city of Piura in northern Peru that frequently present problems of water accumulation which become significant and tragic during the period of the ENSO phenomenon. The analysi...

The present study analyzes the impact of land use and land cover changes (LULCC) on streamflow in the Upper Vilcanota River Basin, Peru. The Soil and Water Assessment Tool (SWAT) model was used to simulate monthly discharges (1982-2016) under two scenarios: 1) the study area with its current land cover and 2) the study area with the disappearance o...

We used the lumped rainfall-runoff hydrologic models Génie Rural à 4, 5, 6 paramètres Journalier (GR4J, GR5J and GR6J) to evaluate the most robust model for simulating discharge on four forested small catchments (<40 ha) in south-central Chile. Different evapotranspiration methods were evaluated: Oudin, Hargreaves-Samani and Priestley-Taylor. Oudin...
Article

This study investigates the applicability of Satellite Precipitation Products (SPPs) in near real-time for the simulation of sub-daily runoff in the Vilcanota River basin, located in the southeastern Andes of Peru. The data from rain gauge stations are used to evaluate the quality of Integrated Multi-satellite Retrievals for GPM–Early (IMERG-E), Gl...
Article

This article identifies homogeneous precipitation regions in Ecuador and their relationship to the El Niño-Southern Oscillation (ENSO), using monthly records from 215 rain stations for the 1968–2014 period. A k-means clustering analysis was used to divide the study area into k regions based on monthly and annual precipitation variables and geograph...
Article
Full-text available
Evapotranspiration (ETo) is one of the most important variables of the water cycle when water requirements for irrigation, water resource planning or hydrological applications are analyzed. In this context, models based on artificial neural networks (ANN) of the retro-propagation type can be an alternative method to estimate ETo in highland regions...
Article
Full-text available
Peruvian Pacific drainage catchments only benefit from 2% of the total national available freshwater while they concentrate almost 50% of the population of the country. This situation is likely to lead a severe water scarcity and also constitutes an obstacle to economic development. Catchments runoff fluctuations in response to climate variability...

La vertiente del Pacífico peruano solo se beneficia del 2% del total del agua superficial disponible a nivel nacional, mientras concentra casi el 50% de la población del país. Las fluctuaciones de caudales en las numerosas cuencas de esta región en respuesta a la variabilidad climática y/o las actividades humanas se pueden reflejar en eventos extre...

In Ecuador and Peru, geochemical information from Pacific coastal rivers is limited and scarce. Here, we present an unedited database of major element concentrations from five HYBAM observatory stations monitored monthly between 4 and 10 years, and the discrete sampling of 23 Andean rivers distributed along the climate gradient of the Ecuadorian an...
Thesis
Full-text available
Climate variability and associated extreme events as El Niño phenomenon (ENSO) represent the most difficult episodes to deal with along the Peruvian Pacific slope and coast. In addition, a growing water concern takes place since seventies. In-depth documentation of precipitation and runoff regimes becomes a key part in any water management plan and...

At the global scale and on geological time scales, mechanical erosion and chemical weathering budgets are linked. Together, these processes contribute to the formation and the degradation of the Earth’s critical zone and to the biogeochemical cycles of elements. In young orogenic belts, climate and tectonic subsidence control together the rate of t...

Article
Full-text available
The use of TRMM satellite daily information (Tropical Rainfall Measuring Mission) is proposed to estimate extreme precipitation over ungauged areas and time periods. Assuming precipitation non-stationarity as signal fluctuations due to the ENSO impact, it is possible to find common features between in-situ and TRMM data sets by multi-resolution ana...

La relación entre El Niño Oscilación del Sur (ENOS) y la precipitación a lo largo de la vertiente del Pacífico del Perú es estudiada durante el periodo de 1964 a 2011 sobre la base del empleo de un producto regionalizado de 9 regiones homogéneas de precipitación y de la utilización de 3 índices ENOS principales. Estos índices representan los dos ti...

The relationship between El Niño Southern Oscillation (ENSO) and precipitation along the Peruvian Pacific coast is investigated over 1964-2011 on the basis of a variety of indices accounting for the different types of El Niño events and atmospheric and oceanographic manifestations of the interannual variability in the tropical Pacific. We show the...

Understanding the climate dynamics in mountainous areas still remains a challenge. For Peruvian areas situated above 3000 m three aspects concerning the temperatures are developed with in-situ and NCEP NCAR Reanalysis from National Center for Environmental Prediction and National Center for Atmospheric Research (NNR) data: a) Based on in-situ tempe...

In an attempt to estimate the spatial and temporal behaviour of rainfall over the mountainous areas of the Peruvian Andes, a new in situ monthly rainfall dataset has been collected (1998–2007) and compared with Tropical Rainfall Measuring Mission (TRMM) 3B43 monthly precipitation data for regions located above 3000 m. The reliability of the TRMM 3B...

FRIEND-Water is investigating long-term variations and changes in hydrological variables to better understand the climate, river basin and human controls on the spatial and temporal distribution of water. The science and training supported by the FRIEND-Water programme are critical for: water resources management, socio-economic development, safeguard the environment, and assessing the impact of global change, including climate change and human impact. As a cross-cutting theme of UNESCO’s International Hydrology Program (IHP), FRIEND-Water contributes to research on: 1) regional water resources, 2) water-related disasters (such as floods and droughts), global change and the water cycle, and water education and capacity building. The FRIEND-Water programme complements and interacts with many national projects and international initiatives.
Project
Hydroclimatic regime and Impacts over coastal basins associated with Land-Ocean-Atmosphere transfer: An insightful hydroclimatological research along Peruvian and Ecuadorian Pacific drainage catchments for the 1970-2010 period, seeking to understand the influence of climate variability and climate change over rainfall and runoff regimes. It is based on proposed methodological schemes for regionalization, frequency variability analysis, hydroclimatic disparity analysis, rainfall-runoff modelling and sensitivity to climate change.
