PREDICTION OF WAVE OVERTOPPING AT VERTICAL BREAKWATER

Coastal structures are designed and constructed to protect coastal regions against storm waves and high water levels during storm surges. Reliable prediction of waveovertopping plays a significant role in the design and safety assessment of these structures. Excessive wave overtopping can harm people, damage vehicles, anddamage properties on or close to the breakwaters. Commonly, the mean wave overtopping rate should be below an acceptable rate under the design conditions.Construction of a higher structure produces more protection than a lower one, but it would be costly and greatly impair the harbor aesthetics [1] For the design, safety assessment and rehabilitation of coastal structures, reliable predictions of wave overtopping are required. Several design formulae exist for simplified types of dikes, rubble-mound breakwaters and vertical breakwaters [2]. The prediction of wave overtopping has been studied by various researchers like Franco et al., (1994) [3], EurOtop (2007) [4], Goda (2009) [5].in this study we use the method of decision tree for developing the previous and predicting the wave overtopping rate for vertical breakwaters. The proposed were trained and validated using the selected small scale data from the CLASH database [6]. The results were also data from the CLASH database [6]. The results were also compared to those of previous empirical formulae.
