  • Aplicación de enzimas como auxiliares en tintura de lana 

    Riva Juan, Ascensión; Alsina Torrent, José María; Prieto Fuentes, María Remedios (Instituto de Investigación Textil y Cooperación Industrial, 1999-01)
    Article
    Open Access
    Il s’agit d’une étude comparée sur l’action de trois enzymes ajoutées au bain de teinture comme adjuvants. Nous avons déterminé les absorptions de colorant, les différences de couleur entre les laines teintées avec et sans ...
  • Beach profile evolution towards equilibrium from varying initial morphologies 

    Eichentopf, Sonja; Van der Zanden, Joep; Cáceres Rabionet, Iván; Alsina Torrent, José María (2019-11)
    Article
    Open Access
    The evolution of different initial beach profiles towards the same final beach configuration is investigated based on large-scale experimental data. The same wave condition was performed three times, each time starting ...
  • Influence of storm sequencing on breaker bar and shoreline evolution in large-scale experiments 

    Eichentopf, Sonja; Van der Zanden, Joep; Cáceres Rabionet, Iván; Baldock, Tom E.; Alsina Torrent, José María (2020-04)
    Article
    Restricted access - publisher's policy
    New large-scale experiments on the influence of storm sequencing on beach profile evolution are presented. The experiments comprised three sequences that commenced from the same initial beach profile. Each sequence consisted ...
  • Lagrangian simulation of suspended sediment in the swash zone 

    Alsina Torrent, José María; Cáceres Rabionet, Iván; Sospedra Iglesias, Joaquim; Baldock, Tom E. (2009-01-01)
    Article
    Restricted access - publisher's policy
    A numerical model is presented to simulate the sediment transport and beach morphology in the swash zone. The model resolves the non-linear shallow water equations in an Eulerian framework and then solves the advection-diffusion ...
  • Long wave generation induced by differences in the wave-group structure 

    Padilla, Enrique; Alsina Torrent, José María (Wiley, 2018-12)
    Article
    Open Access
    The propagation of bichromatic wave groups with differences in the wave-group structure and its influence in long-wave generation are investigated. The wave-group structure is controlled by the number of wave groups (Ng) ...
  • Morphodynamics of sandy beaches under the influence of storm sequences: current research status and future needs 

    Eichentopf, Sonja; Karunarathna, Harshinie U.; Alsina Torrent, José María (2019-09)
    Article
    Open Access
    This paper reviews and discusses the current research status, trends, and future needs in the field of beach morphodynamics under the influence of storm sequences. The paper reviews how the three main research methods, ...
  • New CCM technique for sheet flow measurements and its first applocation in swash zone experiments 

    Van der Zanden, Joep; Alsina Torrent, José María; Cáceres Rabionet, Iván; Buijsrogge, R.H.; Ribberink, Jan (International Association of Hydrological Sciences (IAHS), 2013)
    Conference report
    Restricted access - publisher's policy
    We present here a new conductivity-based system for measuring concentrations and grain velocities in the sheet-flow layer. The system is equipped with a new technique that translates measured concentrations back into ...
  • Sediment suspension events in the inner surf and swash zone. Measurements in large-scale and high-energy wave conditions 

    Alsina Torrent, José María; Cáceres Rabionet, Iván (2011-08)
    Article
    Restricted access - publisher's policy
    The present study presents a database of hydrodynamic properties and suspended sediment concentration collected within the inner surf and swash zones aiming to improve the current understanding of the sediment dynamics ...
  • Sediment transport and beach profile evolution induced by bi-chromatic wave groups with different group periods 

    Alsina Torrent, José María; Padilla, Enrique; Cáceres Rabionet, Iván (2016-08)
    Article
    Open Access
    In this paper, large-scale experimental data are presented showing the beach profile morphological evolution induced by four different bi-chromatic wave conditions characterized by very similar energy content between them ...
  • The effect of air bubbles on optical backscatter sensor measurements under plunging breaking waves 

    Cáceres Rabionet, Iván; Alsina Torrent, José María; Van der Zanden, Joep; Van Der A, Dominic; Ribberink, Jan; Sánchez-Arcilla Conejo, Agustín (2020-08)
    Article
    Restricted access - publisher's policy
    Accurate suspended sediment concentration measurements are key to understand and quantify the sediment transport patterns in the surf and swash zones. One of the most widely used instruments to collect suspended sediment ...
  • The influence of wave groups and wave-swash interactions on sediment transport and bed evolution in the swash zone 

    Alsina Torrent, José María; Van der Zanden, Joep; Cáceres Rabionet, Iván; Ribberink, Jan (2018-10-01)
    Article
    Restricted access - publisher's policy
    Large scale laboratory measurements of sediment dynamics in the swash zone are presented. Two bichromatic wave group conditions were generated, having the same energy content but different wave group period (Tg = 15.0 s ...
  • The physical oceanography of the transport of floating marine debris 

    van Sebille, Erik; Aliani, Stefano; Lavender Law, Kara; Alsina Torrent, José María (2020-02)
    Article
    Open Access
    Marine plastic debris floating on the ocean surface is a major environmental problem. However, its distribution in the ocean is poorly mapped, and most of the plastic waste estimated to have entered the ocean from land is ...
