Modelagem hidrológica de uma bacia com uso intensivo de água : caso do rio Quaraí - RS
(2011) [Artigo de periódico]Bacias hidrográficas com usos muito intensos de água e com a presença de muitos reservatórios pequenos, sobre os quais não se dispõem de informações completas, são bastante comuns no Brasil. As séries hidrológicas em postos ... -
Modelagem hidrológica e hidráulica de grande escala com propagação inercial de vazões
(2015) [Artigo de periódico]Modelos hidrológicos são capazes de representar processos do ciclo hidrológico através de equações matemáticas. Dentre esses processos, a propagação de vazão nos rios é de grande importância, especialmente em bacias de ... -
Modeling coordinated operation of multiple hydropower reservoirs at a continental scale using artificial neural network : the case of Brazilian hydropower system
(2021) [Artigo de periódico]Reservoirs considerably affect river streamflow and need to be accurately represented in environmental impact studies. Modeling reservoir outflow represents a challenge to hydrological studies since reservoir operations ... -
Modeling the role of reservoirs versus floodplains on large-scale river hydrodynamics
(2019) [Artigo de periódico]Large-scale hydrologic–hydrodynamic models are powerful tools for integrated water resources evaluation at the basin scale, especially in the context of flood hazard assessment. However, recent model developments have paid ... -
Modelo hidrodinâmico 1D para redes de canais baseado no esquema numérico de MacCormack
(2011) [Artigo de periódico]Os modelos hidrodinâmicos baseados em esquemas numéricos explícitos vem se tornando atraentes pela facilidade de paralelização do seu código de programação. Este artigo apresenta a proposta de um modelo hidrodinâmico ... -
On the discretization of river networks for large scale hydrologic-hydrodynamic models
(2021) [Artigo de periódico]The discretization of river networks is a critical step for computing flow routing in hydrological models. However, when it comes to more complex hydrologic-hydrodynamic models, adaptations in the spatial representation ... -

Patterns and drivers of evapotranspiration in South American wetlands
(2023) [Artigo de periódico]Evapotranspiration (ET) is a key process linking surface and atmospheric energy budgets, yet its drivers and patterns across wetlandscapes are poorly understood worldwide. Here we assess the ET dynamics in 12 wetland ... -
Previsão de cheias por conjunto em curto prazo
(2014) [Artigo de periódico]Nesse trabalho é apresentada uma aplicação da abordagem da previsão de cheias por conjunto em curto prazo a uma bacia de médio porte localizada na região sudeste do Brasil, a bacia do rio Paraopeba. Para geração das previsões ... -
River discharge in South America : agreement and contradictions between recent alteration and projected changes
(2023) [Artigo de periódico]Climate scenarios are important information for water planning, but, in some cases, they disagree with recent climate alterations, which affects their robustness and reliability. Robustness evaluation can help identifying ... -
SARDIM : a real-time hydrological monitoring platform of South American rivers
(2023) [Artigo de periódico]Due to the frequent occurrence of extreme hydrological events in the South American rivers, this work aims to develop a hydrological monitoring platform open to the public, with a wide and intuitive access, using resources ... -
Seasonal streamflow forecasting in South America's largest rivers
(2023) [Artigo de periódico]Study region: South America large basins (>5000 km²). Study focus: This work represents a first assessment of seasonal streamflow forecasts in South America based on a continental-scale application of a large scale ... -
A simple model of flood peak attenuation
(2024) [Artigo de periódico]A simple analytical model was developed for evaluating the attenuation of flood wave peak discharge. The physically-based model represents the flood wave along its trajectory, based on the diffusive model. Relative peak ... -
Sub-seasonal streamflow forecasts for hydropower dams in the brazilian eletrical interconnected system
(2024) [Artigo de periódico]Inflow prediction on sub-seasonal timescale have the potential for important contributions to the management of water resources in hydroelectric dam operations. These forecasts challenge the limitations of the medium-term ... -
Synergistic calibration of a hydrological model using discharge and remotely sensed soil moisture in the Paraná river basin
(2021) [Artigo de periódico]Hydrological models are useful tools for water resources studies, yet their calibration is still a challenge, especially if aiming at improved estimates of multiple components of the water cycle. This has led the hydrologic ... -
The potential impact of new Andean dams on Amazon fluvial ecosystems
(2017) [Artigo de periódico]Increased energy demand has led to plans for building many new dams in the western Amazon, mostly in the Andean region. Historical data and mechanistic scenarios are used to examine potential impacts above and below six ... -
Toward continental hydrologic–hydrodynamic modeling in South America
(2018) [Artigo de periódico]Providing reliable estimates of streamflow and hydrological fluxes is a major challenge for water resources management over national and transnational basins in South America. Global hydrological models and land surface ... -
Uncertainty assessment in hydrodynamic modeling of floods generated by dam break
(2018) [Artigo de periódico]The objective of the present work was to evaluate sources of uncertainty in dam break simulations for areas with contrasting characteristics: one in a narrow valley with high slopes, and another an open valley with low ... -
Use of large-scale hydrological models to predict dam break-related impacts
(2020) [Artigo de periódico]In this research study, the MGB-IPH (acronym for Large Scale Model in Portuguese - Modelo de Grandes Bacias) was used to simulate the propagation of a dam breach hydrograph estimated from predictor equations for the Três ...
