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 ... -
ANDES: The first system for flash flood monitoring and forecasting in Peru
Lavado-Casimiro, W.; Jimenez, Juan C.; Llauca, Harold; Karen, Leon; Oria, Clara; Llacza Rodríguez, Alan; Huerta, Adrian; Felipe-Obando, Oscar; Acuña Azarte, Julia; Rau, Pedro; Abad, Jorge
(European Geosciences Union, 2020)Acceso abiertoHydrological hazards related to flash floods (FF) in Peru have caused many economic and human life losses in recent years. In this context, developing complete early warning systems against FF is necessary to cope impacts. ... -
Asimilación de caudales observados en la modelación hidrológica subdiaria del río Vilcanota en la estación Pisac
Llauca, Harold
(Servicio Nacional de Meteorología e Hidrología del Perú, 2022-12)Acceso abiertoEn el presente estudio se evalúan dos esquemas de asimilación de datos del tipo secuencial integrados al modelo GR4H en la cuenca Vilcanota en Pisac. Para su aplicación se perturbaron dos productos de precipitación estimada ... -
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 ... -
Constraining Flood Forecasting Uncertainties through Streamflow Data Assimilation in the Tropical Andes of Peru: Case of the Vilcanota River Basin
Llauca, Harold; Arestegui, Miguel; Lavado-Casimiro, W.
(MDPI, 2023-11)Acceso abiertoFlood modeling and forecasting are crucial for managing and preparing for extreme flood events, such as those in the Tropical Andes. In this context, assimilating streamflow data is essential. Data Assimilation (DA) seeks ... -
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 ... -
Estudio de modelamiento hidrológico a paso diario a nivel nacional para el monitoreo de potenciales inundaciones
Llauca, Harold
(Servicio Nacional de Meteorología e Hidrología del Perú, 2021-12)Acceso abiertoLas inundaciones son uno de los desastres naturales más recurrentes en el Perú que afectan la salud y causan graves daños a la propiedad pública y privada. Las amenazas de datos hidrológicos en todo el territorio peruano ... -
Implementation of a flood forecasting system in a transboundary river basin, Peru – Ecuador
Leon, Karen; Acuña Azarte, Julia; Llauca, Harold; Lavado-Casimiro, W.; Suarez, Wilson; Ordoñez, Jorge; Felipe-Obando, Oscar
(European Geosciences Union, 2020)Acceso abiertoThe Peruvian Service of Meteorology and Hydrology (SENAMHI) provides hydro-climatological hazard information to population and decision-makers about flood forecasting and warning on the whole territory of Peru. For flash ... -
Modelamiento hidrológico a paso mensual para el monitoreo de sequías hidrológicas en cuencas de la vertiente del Pacífico y del Titicaca
Llauca, Harold
(Servicio Nacional de Meteorología e Hidrología del Perú, 2019-12)En el Perú, la baja densidad de estaciones hidrométricas y su corta longitud de registro dificultan el monitoreo continuo de caudales a nivel nacional. Por ello, el enfoque de regionalización de parámetros de modelos ... -
Monthly semi-distributed hydrological model at national scale in Peru
Llauca, Harold; Lavado-Casimiro, W.; Montesinos Cáceres, Cristian Albert; Rau, Pedro
(European Geosciences Union, 2020)Acceso abiertoSurface water resources in Peru are heterogeneously distributed in three drainage areas (Pacific, Titicaca, and Atlantic), and their quantification is relevant for planning in economic activities such as water supply and ... -
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 ... -
Surface water resources assessment in Peru through SWAT hydrological model
Asurza Véliz, Flavio Alexander; Traverso-Yucra, Kevin Arnold; Lavado-Casimiro, W.; Felipe-Obando, Oscar; Montesinos Cáceres, Cristian Albert; Llauca, Harold
(European Geosciences Union, 2020)Acceso abiertoSurface water resources in Peru show high spatio-temporal variability, being the prediction of streamflow at ungauged sites, one of the fundamental challenges today. This research presents a methodology for regional ...
