Generation and runup of triple solitary waves on plane slope

Abstract eng:
An experimental study on generation and runup of the wave train of three solitary waves (referring as Triple Solitary Waves, TSW) on a plane slope has been conducted in a wave flume. The modified Goring’s method and the third order solution of a solitary wave are integrated to generate a wave train of three solitary waves with different distance between the crests of two successive solitary waves. Time series of the surface elevation and waterline movement are measured. With regard to a train of three solitary waves with same height, the runup amplification coefficient of the individual wave varies and the runup coefficient of the second wave is smallest among them. Details of experimental results and discussion on the details of velocity field and energy budget of TSW will be presented.
