    Article
    Accés restringit per política de l'editorial
    The severity of the impact of a natural hazard on a society depends on, among other factors, the intensity of the hazard and the exposure and resistance ability of the elements at risk (e.g., persons, buildings and ...
  • Comparing kinematically detachable rock masses and rockfall scar volumes 

    Mavrouli, Olga Christina; Corominas Dulcet, Jordi (Institute of Physics (IOP), 2015)
    Text en actes de congrés
    Accés obert
    In rockfall prone areas the evaluation of the risk due to worst case scenarios requires the establishment of maximum thresholds for the expected rockfall volumes. The magnitude of such instabilities is often related to ...
  • Comparison of block size distribution in rockfalls 

    Ruiz Planas, Montserrat; Corominas Dulcet, Jordi; Mavrouli, Olga Christina (2015)
    Comunicació de congrés
    Accés restringit per política de l'editorial
    Rock masses detached as rockfalls usually disintegrate upon impact on the ground surface. The knowledge of the Rockfall Block Size Distribution (RBSD) generated by the propagation of the rockfall mass is required for th e ...
  • Evaluation of the susceptibility to failure of rocky slopes based on the SMR index

    Comunicació de congrés
    Accés restringit per política de l'editorial
    Fragmentation is a common feature of rockfalls that exerts a strong influence over the trajectories of the generated blocks, the impact energies and the runout. Real scale rockfall tests have traditionally been designed ...
  • Methodology to evaluate rock slope stability under seismic conditions at Solà de Santa Coloma, Andorra 

    Mavrouli, Olga Christina; Corominas Dulcet, Jordi; Wartman, J (2009)
    Article
    Accés obert
    An analytical methodology is presented to evaluate rock slope stability under seismic conditions by considering the geomechanical and topographic properties of a slope. The objective is to locate potential rockfall source ...

    Mavrouli, Olga Christina; Hurlimann Ziegler, Marcel; Abancó Martínez de Arenzana, Clàudia; Moya Sánchez, José; Copons Llorens, Ramon; Ruiz Carulla, Roger (2016)
    Text en actes de congrés
    Accés restringit per política de l'editorial
    The paper presents the experience of two instrumented sites in the Pyrenees where debris flows and rock falls occur frequently. The first one is the debris-flow monitoring system in the Rebaixader catchment, Central Pyrenees, ...
