    • An empirical comparison of machine learning techniques for dam behaviour modelling 

      Salazar González, Fernando; Toledo Municio, Miguel Ángel; Oñate Ibáñez de Navarra, Eugenio; Morán Moya, Rafael (2015-09)
      Article
      Open Access
      Predictive models are essential in dam safety assessment. Both deterministic and statistical models applied in the day-to-day practice have demonstrated to be useful, although they show relevant limitations at the same ...
    • Análisis de los criterios de clasificaión de balsas de riego 

      Sagrera Díaz, Albert (Universitat Politècnica de Catalunya, 2010-11-01)
      Minor thesis
      Open Access
      La sociedad actual es cada vez más sensible en todo lo que se refiere a su seguridad. Por esta razón, se exige que las presas y balsas sean cada vez más seguras. Esto implica la adopción en todos los ámbitos de distintas ...
    • Data-based models for the prediction of dam behaviour: a review and some methodological considerations 

      Salazar González, Fernando; Morán Moya, Rafael; Toledo Municio, Miguel Ángel; Oñate Ibáñez de Navarra, Eugenio (2017-01)
      Article
      Open Access
      Predictive models are an important element in dam safety analysis. They provide an estimate of the dam response faced with a given load combination, which can be compared with the actual measurements to draw conclusions ...
    • Interpretation of dam deformation and leakage with boosted regression trees 

      Salazar González, Fernando; Toledo Municio, Miguel Ángel; Oñate Ibáñez de Navarra, Eugenio; Suárez Arroyo, Benjamín (2016-07)
      Article
      Open Access
      Predictive models are essential in dam safety assessment. They have been traditionally based on simple statistical tools such as the hydrostatic-season-time (HST) model. These tools are well known to have limitations in ...
    • Procedimiento para la evaluación del estado de seguridad en presas y priorización de actuaciones 

      Conesa Baños, Francisco José (Universitat Politècnica de Catalunya, 2010-05-20)
      Minor thesis
      Open Access
      Tradicionalmente, la gestión de la seguridad de presas y las actuaciones de mantenimiento han implicado actividades realizadas de forma sistemática y periódica, como las inspecciones ordinarias, intervenciones correctiva ...
    • Proyecto de mejora del aliviadero de crecidas de la presa de Motz 

      Moles Dimartino, Jaime Alfredo (Universitat Politècnica de Catalunya, 2012-01-23)
      Master thesis (pre-Bologna period)
      Open Access
      La presa de gravedad de Motz, construida sobre el curso del río Fier a 20 km de Annecy (Alta Savoya) y a 5 km de la presa y central eléctrica de Vallières, está situada en la comuna de Motz y constituye el último equipo ...
    • Recent trends in stepped spillway design: behaviour without sidewalls 

      Estrella Toral, Soledad; Sánchez Juny, Martí; Dolz Ripollès, Josep; Ibáñez de Aldecoa, R.; Rodríguez, Jesús; Balairón, Luis (International Commission on Large Dams (ICOLD), 2012)
      Conference report
      Restricted access - publisher's policy
      Until now, hydraulic research of stepped spillways has focused on characterizing aspects as: the different types of flow that occur on the dam, the air inception processes, the potential negative effects associated to the ...
    • Safety analysis of rockfill dams during overspill phenomena 

      Larese De Tetto, Antonia; Rossi, Riccardo; Oñate Ibáñez de Navarra, Eugenio; Idelsohn Barg, Sergio Rodolfo (Bulgarian Committee on Large Dams, 2008)
      Conference report
      Restricted access - publisher's policy
      An increasing interest is rising on the study of rockfill embankment dams during overspilling. Design criteria of earth dams are being reviewed in many countries to guarantee an increasing safety level in front of an ...
    • Velocity and air concentration in air-water flow: application on a stepped spillway without sidewalls 

      Estrella Toral, Soledad; Sánchez Juny, Martí; Dolz Ripollès, Josep; Ibáñez, R.; Domínguez, M.; Balairón, Luis; López, D. (Associação Portuguesa dos Recursos Hídricos, 2012)
      Conference lecture
      Restricted access - publisher's policy
      Until now, hydraulic research of stepped spillways has focused on characterizing aspects as: the different types of flow that occur on the chute, the air inception processes, the potential negative effects associated to ...
