    Article
    Accés restringit per política de l'editorial
    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
    Accés obert
    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)
    Comunicació de congrés
    Accés restringit per política de l'editorial
    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)
    Text en actes de congrés
    Accés obert
    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
    Accés obert
    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)
    Comunicació de congrés
    Accés restringit per política de l'editorial
    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)

    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 ...
  • Modelación numérica de deslizamientos de ladera en embalses mediante el Método de Partículas y Elementos Finitos (PFEM) 

    Salazar González, Fernando; Oñate Ibáñez de Navarra, Eugenio; Morán Moya, Rafael (2012-04)
    Article
    Accés obert
    The paper presents the results of the application of the Particle Finite Element Method (PFEM) to the analysis of landslides in reservoirs. This is a complex phenomenon, because of the interaction between the landslide, ...
  • Numerical and experimental study of overtopping and failure of rockfill dams 

    Larese De Tetto, Antonia; Rossi, Riccardo; Oñate Ibáñez de Navarra, Eugenio; Toledo Municio, Miguel Ángel; Morán Moya, Rafael; Campos, Hibber (2015-08)
    Article
    Accés restringit per política de l'editorial
    This paper aims to present and validate a numerical technique for the simulation of the overtopping and onset of failure in rockfill dams due to mass sliding. This goal is achieved by coupling a fluid dynamic model for the ...
  • Numerical modeling of the hydraulic performance of Oliana dam spillway using Kratos 

    Salazar, Fernando; Morán Moya, Rafael; Rossi, Riccardo; Larese De Tetto, Antonia (2011)
    Text en actes de congrés
    Accés restringit per política de l'editorial
    Head-discharge curves in gated spillways are commonly obtained by means of the application of empirical formulations. The most popular one, recommended by SPANCOLD [1], was developed by the U.S. Army Corps of Engineers ...
