摘      要：The evolution of the nonlinear wave groups in deep water is investigated through laboratory measurements and numerical *** experiments are conducted in deep-water wave tank,focusing on the characteristics of breaking waves arising from the evolved wave *** quantitative results are obtained for the significant breaking wave train,including the surface elevation time series,the local geometry,and the energy dissipation.A nonlinear model for the evolution of the wave groups in deep water is developed by adding eddy viscosity dissipation terms in the High Level Irrotational Green-Naghdi(HLIGN)*** results of the simulation are compared with the laboratory measurements,and good agreement is observed for the evolved wave train.
