A future of extreme precipitation and droughts in the Peruvian Andes
Potter, Emily R.; Fyffe, Catriona L.; Orr, Andrés; Quincey, Duncan J.; Ross, Andrés N.; Rangecroft, Sally; Medina, Katy; Burns, Helen; Llacza, Alan; Jácome, Gerardo; Hellström, Robert Å.; Castro, Josué; Cochachín, Alejo; Montoya, Nilton; Loarte, Edwin; Pellicciotti, Francesca
(Springer Nature, 2023)Acceso abiertoRunoff from glacierised Andean river basins is essential for sustaining the livelihoods of millions of people. By running a highresolution climate model over the two most glacierised regions of Peru we unravel past climatic ... -
A multi-objective approach to select hydrological models and constrain structural uncertainties for climate impact assessments
Saavedra, Danny; Mendoza, Pablo A.; Addor, Nans; Llauca, Harold; Vargas, Ximena
(John Wiley and Sons, 2021-12)The assessment of climate change impacts on water resources and flood risk is typically underpinned by hydrological models calibrated and selected based on observed streamflow records. Yet, changes in climate are rarely ... -
Assessing near real-time satellite precipitation products for flood simulations at sub-daily scales in a sparsely gauged watershed in Peruvian andes
Llauca, Harold; Lavado-Casimiro, W.; León, Karen; Jimenez, Juan C.; Traverso-Yucra, Kevin Arnold; Rau, Pedro
(MDPI AG, 2021-02-23)Acceso abiertoThis 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 ... -
Assessment of Present and Future Water Security under Anthropogenic and Climate Changes Using WEAP Model in the Vilcanota-Urubamba Catchment, Cusco, Perú
Goyburo, Andrés; Rau, Pedro; Lavado-Casimiro, Waldo; Buytaert, Wouter; Cuadros-Adriazola, José; Horna, Daniel
(MDPI AG, 2023)Acceso abiertoWater is an essential resource for social and economic development. The availability of this resource is constantly threatened by the rapid increase in its demand. This research assesses current (2010–2016), short- ... -
Atmospheric transmissivity: distribution and empirical estimation around the central Andes
Baigorria, Guillermo; Villegas, Esequiel B.; Trebejo, Irene; Carlos, Jose F.; Quiroz, Roberto
(John Wiley & Sons, 2004)Acceso abiertoThis study of the distribution in space and time of atmospheric transmissivity τ takes into account the fact that, in complex terrain, many factors affect this variable; thus, it is not possible to use the generalizations ... -
Benefits of the coupling in the downscaling the South American climate
Ordoñez, Jorge; Paredes, Jonathan; Vázquez, Rubén; Llacza, Alan; Jacome, Gerardo; De la Cruz, Gustavo; Llamocca, Jorge; Acuña, Delia; Sein, Dmitry V.; Álvarez, Erick; Cabos, William
(Elsevier, 2024)Acceso abiertoWe evaluate the benefits of the use of a regional coupled model over its stand-alone atmospheric component when forced by reanalysis data in the simulation of the South American climate. We find that the coupling allows ... -
Construction of a daily streamflow dataset for Peru using a similarity-based regionalization approach and a hybrid hydrological modeling framework
Llauca, Harold; Leon, Karen; Lavado-Casimiro, W.
(Elsevier, 2023)Acceso abiertoThis paper aims to develop a national hydrological model using physiographic and climatic characteristics to identify donor and receptor sub-catchments (sub-zones). Therefore, we use the hydrometeorological PISCO dataset ... -
PISCO_HyM_GR2M: A Model of Monthly Water Balance in Peru (1981–2020)
Llauca, Harold; Lavado-Casimiro, W.; Montesinos Cáceres, Cristian Albert; Santini, W.; Rau, Pedro
(MDPI AG, 2021-04-10)Acceso abiertoQuantification 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 ...
