  • Internal solitary wave(ISW) propagation is influenced by some physical factors.The most important factor of all is topography seabed in the ocean.Due to difficulties in field investigation,a wave flume was produced and tests were carried out to observe ISW propagation in the laboratory.The research shows that the classification of wave-ridge encounter can be divided into weak interaction,moderate interaction and strong interaction,and that a non-dimensional blockage parameter may be applied efficiently to determine the classification of wave-ridge encounter,being below 0.5 for the weak interaction,0.5 to 0.7 for the moderate interaction and over 0.7 for the strong interaction.Furthermore,the non-dimensional propagation speed of an ISW declines and the dissipation of wave energy increases as the blockage parameter increases.
