  • Coherent structures in oscillatory flows within the laminar-to-turbulent transition regime for smooth and rough walls 

    Mujal Colilles, Anna; Christensen, Kenneth T.; Bateman Pinzón, Allen; Garcia, Marcelo Horacio (2016-04)
    Article
    Accés restringit per política de l'editorial
    We investigate coherent structures present in oscillatory boundary layers over smooth and rough beds for Reynolds numbers between 103 and 104, in the transition to turbulence regime. A two-camera 2D- particle image velocimetry ...
  • Analysis of river bed dynamic evolution following a landslide dam 

    Del Sasso, S.F; Sole, Aurelia; Bateman Pinzón, Allen; Medina Iglesias, Vicente César de; Mirauda, Domenica; Volpe Plantamura, Antonio; Giosa, Luciana; Guariglia, Annibale (2015-12)
    Article
    Accés obert
    Landslides and debris flows can strongly interact with the river network and its mass transport processes, determining modifications of the river pattern with consequent effects on the hydrodynamic phenomena, alterations ...
  • Morpho-fluvial analysis of headwater catchments: an example from the Central-Eastern Pyrenees 

    Chevalier, Guillaume Gerard; Medina Iglesias, Vicente César de; Hurlimann Ziegler, Marcel; Bateman Pinzón, Allen (2015-05)
    Article
    Accés obert
    Geomorphometry of headwater catchments has been poorly reported in the Central-Eastern Pyrenees. This study presents a series of parameters obtained for Central-Eastern Pyrenean headwater catchments. The database consists ...
  • Vortex rings impinging on permeable boundaries 

    Mujal Colilles, Anna; Dalziel, Stuart; Bateman Pinzón, Allen (2015-01)
    Article
    Accés obert
    Experiments with vortex rings impinging permeable and solid boundaries are presented in order to investigate the influence of permeability. Utilizing Particle Image Velocimetry, we compared the behaviour of a vortex ring ...

  • Assessment methodology for the prediction of landslide dam hazard 

    Del Sasso, S.F; Sole, Aurelia; Pascale, Stefania; Sdao, Francesco; Bateman Pinzón, Allen; de Medina Iglesias, Vicente César (2014-03)
    Article
    Accés obert
    This paper represents a contribution to the study of hazard caused by the interaction between landslides and river courses. The effects of such interferences are often catastrophic and could include the formation of upstream ...
  • Debris-flow susceptibility analysis using fluvio-morphological parameters and data mining: application to the Central-Eastern Pyrenees 

    Chevalier, Guillaume Gerard; Medina Iglesias, Vicente César de; Hurlimann Ziegler, Marcel; Bateman Pinzón, Allen (2013-06)
    Article
    Accés restringit per política de l'editorial
    Based on debris-flow inventories and using a geographical information system, the susceptibility models presented here take into account fluvio-morphologic parameters, gathered for every first-order catchment. Data mining ...
