Spatial Evolution of Laboratory Generated Freak Waves in Deep water Depth

摘要

In the present paper experimental generated Freak Waves are investigated as they are defiend as transient waves existing in one certain location in one definite instant in time (Kaldenhoff & Schlurmann, 1999). Freak Waves occur due to superposition of numerous wave components of a real sea state and are typically characterized by an extreme waveheight. Moreover, it is determined that Freak Waves are sometimes identified by spilling breaking (Schlurmann, 1999 or Kway et al., 1998). The characteristics of Freak Waves were investigated in spatial domain. Interestingly, laboratory generated waves with extreme waveheights show significant similarities to results from field observations from real sea states, e.g. observed by Sand et al. (1989), Yasuda et al. (1997) or Rozario et al. (1993).
