Abstract

Laboratory experiments and numerical simulations were conducted to investigate the characteristics of bores generated by gate-operation. The laboratory tests showed that the gate operation method affected the generation of undular bore, then the condition of immediate formation of undular bore was formulated by a parameter of gate-operation. The numerical simulation with the non-linear dispersive wave theory accurately reproduced the waveform and celerity observed in the laboratory experiments. Furthermore, an influence of gate operation method on the deformation process and the amplitude of undular bore was considered by the numerical experiments.
