.... The valve-pump system is proved to produce the surge wave precisely and delicately. The superimposition appears that the solitary waves ride on the surge wave. The surge wave acts as the deeper water for the solitary wave to propagate, which affects the amplitude of solitary waves. In the present study, two...

In this paper, the nonlinear yawing of the barge with internal turret mooring systems in bidirectional and bichromatic waves was investigated by a second-order time-domain method. The results indicate that large-amplitude...

... over a submerged ridge, laboratory experiments by using plunging wavemaker are run in the study. Laboratory results reveal that the amplitude of SWs decreases as the fluid changes from homogeneous into stratified. At the slow wavemaker speed, the wave period of SWs has a significant decrease when...
