    • Developments in acoustics for studying wave-driven boundary layer flow and sediment dynamics over rippled sand-beds 

      Thorne, Peter D.; Hurther, David; Cooke, Richard D.; Cáceres Rabionet, Iván; Barraud, P.A.; Sánchez-Arcilla Conejo, Agustín (2018-08)
      Article
      Open Access
      The processes of sediment entrainment, transport, and deposition over bedforms are highly dynamic and temporally and spatially variable. Obtaining measurements to understand these processes has led to ongoing developments ...
    • 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 ...
    • On the study of boundary layer sediment transport processes using new developmental acoustic techniques 

      Thorne, Peter D.; Hurther, David; Cooke, Richard D.; Barraud, P.A.; Barnoud, J.M.; Cáceres Rabionet, Iván; Sánchez-Arcilla Conejo, Agustín (2013)
      Conference report
      Open Access
      This study aims at presenting a set of novel acoustic flow and sediment measuring tools used in a complementary way for the investigation of fine-scale flow and sediment transport processes above a rippled sand bed under ...
    • 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 evolution of mobile bed tests: a step towards the future of coastal engineering 

      Sánchez-Arcilla Conejo, Agustín; Cáceres Rabionet, Iván; Thorne, Peter D.; Eiff, Olivier; Lacaze, Laurent; Hurther, David; Barraud, P.A.; Musumerci, Rosaria; Vousdoukas, Michalis; Sancho, Francisco (2013)
      Conference lecture
      Open Access
      Coastal Engineering still presents significant levels of uncertainty, much larger for sediment transport and morphodynamics than for the driving hydrodynamics. Because of that there is still a need for experimental research ...
    • Wave boundary layer hydrodynamics and sheet flow properties under large-scale plunging-type breaking waves 

      Fromant, Guillaume; Hurther, David; Van der Zanden, Joep; Van Der A, Dominic; Cáceres Rabionet, Iván; O'Donoghue, Tom; Ribberink, Jan (Wiley, 2019-01)
      Article
      Open Access
      Wave boundary layer (WBL) dynamics are measured with an Acoustic Concentration and Velocity Profiler (ACVP) across the sheet flow-dominated wave-breaking region of regular large-scale waves breaking as a plunger over a ...
