    • Assessing the capacity of large-scale hydrologic-hydrodynamic models for mapping flood hazard in southern Brazil 

      Alves, Maria Eduarda Pereira; Fan, Fernando Mainardi; Paiva, Rodrigo Cauduro Dias de; Siqueira, Vinícius Alencar; Fleischmann, Ayan Santos; Brêda, João Paulo Lyra Fialho; Santos, Leonardo Laipelt dos; Araujo, Alexandre Abdalla (2022) [Journal article]
      Mapping flood risk areas is important for disaster management at the local, regional, and national scales. The aim of this study was to evaluate the ability of large-scale models to obtain flood hazard maps. The models ...

    • Efficient number of calibrated cross sections bottom levels on a hydrodynamic model using the SCE-UA algorithm : case study : Madeira River 

      Brêda, João Paulo Lyra Fialho; Bravo, Juan Martín; Paiva, Rodrigo Cauduro Dias de (2017) [Journal article]
      Hydrodynamic models are important tools for simulating river water level and flow. A considerable fraction of the hydrodynamic model errors are related to parameters uncertainties. As cross sections bottom levels considerably ...

    • Global evapotranspiration datasets assessment using water balance in South America 

      Ruhoff, Anderson Luis; Andrade, Bruno César Comini de; Santos, Leonardo Laipelt dos; Fleischmann, Ayan Santos; Siqueira, Vinícius Alencar; Moreira, Adriana Aparecida; Fontana, Rafael Barbedo; Cyganski, Gabriele Leão; Fernandez, Gabriel Matte Rios; Brêda, João Paulo Lyra Fialho; Paiva, Rodrigo Cauduro Dias de; Meller, Adalberto; Teixeira, Alexandre de Amorim; Araujo, Alexandre Abdalla; Fuckner, Marcus Andre; Biggs, Trent (2022) [Journal article]
      Evapotranspiration (ET) connects the land to the atmosphere, linking water, energy, and carbon cycles. ET is an essential climate variable with a fundamental importance, and accurate assessments of the spatiotemporal trends ...

    • Impact of large reservoirs on simulated discharges of Brazilian rivers 

      Passaia, Otávio Augusto; Siqueira, Vinícius Alencar; Brêda, João Paulo Lyra Fialho; Fleischmann, Ayan Santos; Paiva, Rodrigo Cauduro Dias de (2020) [Journal article]
      Tens of thousands of dams were built around the world to reduce flood risks, produce energy, and maximize benefits of limited freshwater resources. In Brazil, the main and largest reservoirs are related to hydropower plants. ...

    • Modeling coordinated operation of multiple hydropower reservoirs at a continental scale using artificial neural network : the case of Brazilian hydropower system 

      Brêda, João Paulo Lyra Fialho; Paiva, Rodrigo Cauduro Dias de; Pedrollo, Olavo Correa; Passaia, Otávio Augusto; Collischonn, Walter (2021) [Journal article]
      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 ...

    • On the discretization of river networks for large scale hydrologic-hydrodynamic models 

      Fan, Fernando Mainardi; Siqueira, Vinícius Alencar; Brêda, João Paulo Lyra Fialho; Fleischmann, Ayan Santos; Paiva, Rodrigo Cauduro Dias de; Pontes, Paulo Rógenes Monteiro; Colischonn, Walter (2021) [Journal article]
      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 ...

    • River discharge in South America : agreement and contradictions between recent alteration and projected changes 

      Miranda, Pedro Torres; Paiva, Rodrigo Cauduro Dias de; Gama, Cléber Henrique Araújo; Brêda, João Paulo Lyra Fialho (2023) [Journal article]
      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 

      Reis, Gustavo Gabbardo dos; Paiva, Rodrigo Cauduro Dias de; Brêda, João Paulo Lyra Fialho; Siqueira, Vinícius Alencar (2023) [Journal article]
      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 ...

    • Water storage variability across Brazil 

      Fontana, Rafael Barbedo; Fleischmann, Ayan Santos; Siqueira, Vinícius Alencar; Brêda, João Paulo Lyra Fialho; Fernandez, Gabriel Matte Rios; Santos, Leonardo Laipelt dos; Teixeira, Alexandre de Amorim; Araujo, Alexandre Abdalla; Fuckner, Marcus Andre; Meller, Adalberto; Fan, Fernando Mainardi; Collischonn, Walter; Ruhoff, Anderson Luis; Paiva, Rodrigo Cauduro Dias de (2022) [Journal article]
      Brazil hosts a large amount of freshwater. Knowing how this stored water is partitioned in space and time between surface and subsurface components is a crucial step towards a more correct depiction of the country’s water ...
