  • Air demand estimation in bottom outlets with the particle finite element method. Susqueda Dam case study 

    Salazar González, Fernando; San Mauro Saiz, Javier; Celigueta Jordana, Miguel Ángel; Oñate Ibáñez de Navarra, Eugenio (Springer, 2017-07)
    Article
    Open Access
    Dam bottom outlets play a vital role in dam operation and safety, as they allow controlling the water surface elevation below the spillway level. For partial openings, water flows under the gate lip at high velocity and ...
  • Análisis experimental y numérico del oleaje producido por la inestabilidad de laderas de embalses 

    Alves, Ricardo; Morán, Rafael; Toledo Municio, Miguel Ángel; Irazábal González, Joaquín; Salazar González, Fernando; Larese De Tetto, Antonia (2015)
    Conference report
    Open Access
    El fenómeno del oleaje causado por deslizamientos de laderas de embalse un escenario formado por dos procesos, uno de tipo geomecánico y otro, hidrodinámico. El primero está relacionado con el origen de la inestabilidad ...
  • 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 ...
  • 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 ...
  • 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 ...
  • 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 ...
  • Design and validation of rockfall protection systems by numerical modeling with discrete elements 

    Latorre, Salvador; Celigueta Jordana, Miguel Ángel; Irazábal González, Joaquín; Salazar González, Fernando; Oñate Ibáñez de Navarra, Eugenio (International Centre for Numerical Methods in Engineering (CIMNE), 2017)
    Conference report
    Open Access
    Rockfall protection systems are installed in order to preserve civil infrastructures against landslides and falling rocks. For the evaluation of these systems,one of the main problems is the difficulty to develop laboratory ...
  • Fluid-soil-structure interaction analysis with the particle finite element method 

    Oñate Ibáñez de Navarra, Eugenio; Celigueta Jordana, Miguel Ángel; Idelsohn Barg, Sergio Rodolfo; Salazar González, Fernando; Suárez Arroyo, Benjamín (Centre Internacional de Mètodes Numèrics en Enginyeria (CIMNE), 2012)
    Part of book or chapter of book

    We present some developments and applications of the Particle Finite Element Method (PFEM) for analysis of complex coupled problems in mechanics involving fluid-soil-structure interaction.
  • Hydraulic and stability analysis of the supporting layer of wedge-shaped blocks 

    San Mauro Saiz, Javier; Larese De Tetto, Antonia; Salazar González, Fernando; Irazábal González, Joaquín; Morán Moya, Rafael; Toledo Municio, Miguel Ángel (Colorado State University, 2016)
    Conference lecture

    Wedge shaped blocks (WSB) are attracting increasing attention as protection against overtopping for earth and rock-fill dams. However, there are limited examples of application and some aspects of the technology merit ...
  • 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 ...
  • A machine learning based methodology for anomaly detection in dam behaviour 

    Salazar González, Fernando (Universitat Politècnica de Catalunya, 2017-02-23)
    Doctoral thesis
    Open Access
    Dam behaviour is difficult to predict with high accuracy. Numerical models for structural calculation solve the equations of continuum mechanics, but are subject to considerable uncertainty as to the characterisation of ...
  • Numerical modelling of landslide-generated waves with the particle finite element method (PFEM) and a non-Newtonian flow model
