    • Large-scale laboratory study of breaking wave hydrodynamics over a fixed bar 

      Van Der A, Dominic; Van der Zanden, Joep; O'Donoghue, Tom; Hurther, David; Cáceres Rabionet, Iván; McLelland, Stuart J.; Ribberink, Jan (2017-04-01)
      Article
      Open Access
      A large-scale wave flume experiment has been carried out involving a T¿=¿4 s regular wave with H¿=¿0.85 m wave height plunging over a fixed barred beach profile. Velocity profiles were measured at 12 locations along the ...
    • Near-bed turbulent kinetic energy budget under a large-scale plunging breaking wave over a fixed bar 

      Van der Zanden, Joep; Van Der A, Dominic; Cáceres Rabionet, Iván; Hurther, David; McLelland, Stuart J.; Ribberink, Jan; O'Donoghue, Tom (Wiley, 2018-01-01)
      Article
      Open Access
      Hydrodynamics under regular plunging breaking waves over a fixed breaker bar were studied in a large-scale wave flume. A previous paper reported on the outer flow hydrodynamics; the present paper focuses on the turbulence ...
    • Nera-bed hydrodynamics and turbulence below a large-scale plunging breaking wave over a mobile barred bed profile 

      Van der Zanden, Joep; van der A, Dominic; Hurther, David; Cáceres Rabionet, Iván; O'Donoghue, Tom; Ribberink, Jan (Wiley, 2016-08-03)
      Article
      Open Access
      Detailed measurements are presented of velocities and turbulence under a large-scale regular plunging breaking wave in a wave flume. Measurements were obtained at 12 cross-shore locations around a mobile medium-sand breaker ...
    • 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)

      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 ...
    • Sand and transport process measurements under large-scale breaking waves 

      Van der Zanden, Joep; Van Der A, Dominic; Ribberink, Jan; O'Donoghue, Tom; Hurther, David; Cáceres Rabionet, Iván; Thorne, Peter D. (2015)
      Conference report
      Open Access
      The effects of wave breaking on sediment transport are studied through a new series of mobile-bed experiments in a large-scale wave flume. During the campaign, one experiment involving detailed sand transport process ...
    • The effect of air bubbles on optical backscatter sensor measurements under plunging breaking waves
