    • Automatic shoreline detection from video images by combining information from different methods 

      Ribas Prats, Francesca; Simarro, Gonzalo; Arriaga García, Jaime; Luque Lozano, Pau (Multidisciplinary Digital Publishing Institute (MDPI), 2020-11-02)
      Article
      Open Access
      Properly registering the time evolution of the shoreline—the coastal land-water interface—is a crucial issue in coastal management, among other disciplines. Video stations have shown to be powerful low-cost tools for ...
    • Breeze influence on waves and vertical current profile in the coastal area based on EOF analysis (Vilanova i la Geltrú, Barcelona) 

      Antonijuan Rull, Josefina; Simarro, Gonzalo; Guillén Aranda, Jorge; Nogueras Cervera, Marc; Manuel Lázaro, Antonio; Palanques Monteys, Albert; Puig, Pere (2013)
      Conference report
      Open Access
      This article presents some preliminary results on the breeze influence on waves and vertical current profiles during eleven months of data recorded by an Acoustic Wave and Current Profiler installed in the OBSEA platform ...
    • Camera calibration for coastal monitoring using available snapshot images 

      Simarro, Gonzalo; Calvete Manrique, Daniel; Souto, Paola; Guillén Aranda, Jorge (Multidisciplinary Digital Publishing Institute (MDPI), 2020-06-06)
      Article
      Open Access
      Joint intrinsic and extrinsic calibration from a single snapshot is a common requirement in coastal monitoring practice. This work analyzes the influence of different aspects, such as the distribution of Ground Control ...
    • Characteristics and dynamics of crescentic bar events at Castelldefels beach 

      Swart, Rinse Leendert de; Ribas Prats, Francesca; Simarro, Gonzalo; Guillén Aranda, Jorge (Consejo Superior de Investigaciones Científicas (CSIC), 2019)
      Conference report
      Open Access
      Crescentic sand bars have been studied intensively in the last decades, resulting in good knowledge of some of their characteristics, but the processes behind their formation and destruction are not yet clear. This study ...
    • Characteristics and dynamics of crescentic bar events in an open, tideless beach 

      Swart, Rinse Leendert de; Ribas Prats, Francesca; Ruessink, Gerben; Simarro, Gonzalo; Guillén Aranda, Jorge (2017)
      Conference report
      Open Access
      Crescentic bar events at Castelldefels beach (NW Mediterranean) have been characterised using a 4.25 years dataset (October 2010-December 2014) of time-exposure video images. Crescentic bars are observed during 41% of ...
    • Characterization of coastal upwelling events during the generation of the water column stratification in spring (Vilanova i la Geltrú, NW Mediterranean) 

      Antonijuan Rull, Josefina; Guillem, Jorge; Simarro, Gonzalo; Nogueras Cervera, Marc; Río Fernandez, Joaquín del (Institute of Electrical and Electronics Engineers (IEEE), 2015)
      Conference report
      Open Access
      This article presents some preliminary results on the characterization of inputs of offshore waters (upwelling events) in the coast off Vilanova i la Geltrú (NW Mediterranean) in the spring of the years 2010, 2012 and 2014. ...
    • The influence of camera calibration on nearshore bathymetry estimation from UAV videos 

      Simarro, Gonzalo; Calvete Manrique, Daniel; Plomaritis, Theocharis; Moreno-Noguer, Francesc; Giannoukakou-Leontsini, Ifigeneia; Montes, Juan; Durán, Ruth (Multidisciplinary Digital Publishing Institute (MDPI), 2021-01-05)
      Article
      Open Access
      Measuring the nearshore bathymetry is critical in coastal management and morphodynamic studies. The recent advent of Unmanned Aerial Vehicles (UAVs), in combination with coastal video monitoring techniques, allows for an ...
    • UBathy: a new approach for bathymetric inversion from video imagery 

      Simarro, Gonzalo; Calvete Manrique, Daniel; Luque Lozano, Pau; Orfila, Alejandro; Ribas Prats, Francesca (Multidisciplinary Digital Publishing Institute (MDPI), 2019-11-20)
      Article
      Open Access
      A new approach to infer the bathymetry from coastal video monitoring systems is presented. The methodology uses principal component analysis of the Hilbert transform of video images to obtain the components of the wave ...
    • ULISES: an open source code for extrinsic calibrations and planview generations in coastal video monitoring systems 

      Simarro, Gonzalo; Ribas Prats, Francesca; Alvarez, Amaya; Guillén Aranda, Jorge; Chic, Oscar; Orfila, Alejandro (2017-09-01)
