    Works carried out to monitor the displacements of the Vallcebre landslide (Pyrenees range, NE of Spain) since 1987 are presented. The landslide, which extends over an area of about 0.8 km2 and affects more than 20 × 106 ...
  • Slope orientation and vegetation effects on soil thermo-hydraulic behavior: an experimental study 

    Oorthuis Gómez, Raül; Vaunat, Jean; Hurlimann Ziegler, Marcel; Lloret Morancho, Antonio; Moya Sánchez, José; Puig i Polo, Càrol; Fraccica, Alessandro (2021-01)
    Article
    Open Access
    The stability and erosion of natural and man-made slopes is influenced by soil-vegetation-atmosphere interactions and the thermo-hydro-mechanical slope conditions. Understanding such interactions at the source of slope ...
  • Analysis of fragmentation of rock blocks from real-scale tests 

    Ruiz Carulla, Roger; Corominas Dulcet, Jordi; Gili Ripoll, José Antonio; Matas Casado, Gerard; Lantada, Nieves; Moya Sánchez, José; Prades Valls, Albert; Núñez Andrés, María Amparo; Buill Pozuelo, Felipe; Puig i Polo, Càrol (2020-08)
    Article
    Open Access
    Real-scale fragmentation tests provide high quality data in order to study the fragmentation pattern of rock blocks. In the tests carried out, the initial rock mass, in terms of both volume and shape, was reconstructed by ...
  • Influence of the mapping unit for regional landslide early warning systems: comparison between pixels and polygons in Catalonia (NE Spain) 

    Palau Berastegui, Rosa Maria; Hurlimann Ziegler, Marcel; Berenguer Ferrer, Marc; Sempere Torres, Daniel (2020-09)
    Article
    Restricted access - publisher's policy
    This work presents a prototype landslide early warning system (LEWS) adapted to real-time performance over the region of Catalonia (NE Spain). The system uses high-resolution rainfall information obtained from weather radar ...
  • Simulation of full-scale rockfall tests with a fragmentation model 

    Matas Casado, Gerard; Lantada, Nieves; Corominas Dulcet, Jordi; Gili Ripoll, José Antonio; Ruiz Carulla, Roger; Prades Valls, Albert (2020-05)
    Article
    Open Access
    In this paper, we present the upgraded version of RockGIS, a stochastic program for the numerical simulation of rockfalls and their fragmentation, based on a fractal model. The code has been improved to account for a range ...
  • Calculation of the rockwall recession rate of a limestone cliff, affected by rockfalls, using cosmogenic chlorine-36: case study of the Montsec range (Eastern Pyrenees, Spain) 

    Domènech Surinyach, Guillem; Corominas Dulcet, Jordi; Mavrouli, Olga Christina (2018-04)
    Article
    Open Access
    Cliff erosion may be a major problem in settled areas affecting populations and producing economic and ecological losses. In this paper we present a procedure to calculate the long-term retreat rate of a cliff affected by ...
  • Recommendations for the quantitative analysis of landslide risk 

    Corominas Dulcet, Jordi; van Westen, Cees; Frattini, P.; Cascini, L; Malet, Jean-Philippe; Fotopoulou, Stavroula D.; Catani, F; Mavrouli, Olga Christina; Pitilakis, Kyriazis D.; Winter, Mike (2014-05)
    Article
    Open Access
    This paper presents recommended methodologies for the quantitative analysis of landslide hazard, vulnerability and risk at different spatial scales (site-specific, local, regional and national), as well as for the verification ...
  • DebrisInterMixing-2.3: a finite volume solver for three-dimensional debris-flow simulations with two calibration parameters. Part 2: Model validation with experiments 

    von Boetticher, A.; Turowski, J; McArdell, Brian, W; Rickenmann, Dieter; Hurlimann Ziegler, Marcel; Scheidl, Christian; Kirchner, J (2017-11)
    Article
    Open Access
    Here, we present validation tests of the fluid dynamic solver presented in von Boetticher et al. (2016), simulating both laboratory-scale and large-scale debris-flow experiments. The new solver combines a Coulomb viscoplastic ...
  • Damage analysis of masonry structures subjected to rockfalls 

    Mavrouli, Olga Christina; Giannopoulos, P. G.; Carbonell Puigbó, Josep Maria; Syrmakezis, Costas (2017-06-01)
    Article
    Open Access
    Masonry structures present substantial vulnerability to rockfalls. The methodologies for the damage quantification of masonry structures subjected to rockfalls are scarce. An analytical procedure for the damage assessment ...
  • RockGIS: a GIS-based model for the analysis of fragmentation in rockfalls 

    Matas Casado, Gerard; Lantada, Nieves; Corominas Dulcet, Jordi; Gili Ripoll, José Antonio; Ruiz Carulla, Roger; Prades Valls, Albert (2017-03-31)
    Article
    Open Access
    A rockfall is a mass instability event frequently observed in road cuts, open pit mines and quarries, steep slopes and cliffs. After its detachment, the rock mass may disaggregate and break due to the impact with the ground ...
  • Recent debris flows in the Portainé catchment (Eastern Pyrenees, Spain): analysis of monitoring and field data focussing on the 2015 event
