      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 ...

    • Analysis of the discharge capacity of radial gated-spillways using CFD and ANN: Oliana Dam case study 

      Salazar González, Fernando; Morán Moya, Rafael; Rossi, Riccardo; Oñate Ibáñez de Navarra, Eugenio (2013-03)
      Article
      Restricted access - publisher's policy
      The paper focuses on the analysis of radial-gated spillways, which is carried out by the solution of a numerical model based on the finite element method (FEM). The Oliana Dam is considered as a case study and the discharge ...

    • Applications of numerical methods in design and evaluation of overtopping protection systems 

      Salazar González, Fernando; San Mauro Saiz, Javier; Larese De Tetto, Antonia; Irazábal González, Joaquín; Morán Moya, Rafael; Oñate Ibáñez de Navarra, Eugenio; Toledo Municio, Miguel Ángel (Colorado State University, 2016)
      Conference lecture
      Restricted access - publisher's policy
      The development of overtopping protection systems often requires detailed analyses of complex physical phenomena. This hinders the comprehensive knowledge of their behavior, and therefore the development of suitable design ...

    • Applications of the particle finite element method in dam engineering 

      Salazar, F.; Pozo, D.; Morán Moya, Rafael; Oñate Ibáñez de Navarra, Eugenio (2011)
      Conference report
      Open Access
      The paper presents the results of the application of the Particle Finite Element Method (PFEM) to the analysis of some of the more complex phenomena related to dam hydraulics: shock waves in spillways, aeration in bottom ...

    • 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 ...

    • Estudio de la capacidad de desagüe de aliviaderos con compuertas mediante modelación numérica: aplicación a la presa de Oliana 

      Salazar, Fernando; Rossi, Riccardo; Morán Moya, Rafael; Larese De Tetto, Antonia (Mcharly.com, 2011)
      Conference lecture
      Restricted access - publisher's policy
      Las curvas de desagüe de aliviaderos con compuertas, que permiten conocer el caudal que se está vertiendo en unas condiciones (nivel de embalse, apertura de compuerta) determinadas, suelen calcularse en base a formulaciones ...

    • Estudios sobre el comportamiento de presas de escollera ante vertidos por coronación 

      Larese De Tetto, Antonia; Lechuga García, Cristina; Lara Dominguez, Ángel; Berga Cano, Mª Isabel; Viña Gómez, Mª del Pilar; Toledo Municio, Miguel Ángel; Morán Moya, Rafael; Campos, Hibber; García Palacio, Jaime (2010)
