This is a study of the interactions of solitary waves climbing up a circular island. A series of large-scale laboratory experiments with waves of different incident height-to-depth ratios and different crest lengths is described. Detailed two-dimensional run-up height measurements and time histories of surface elevations around the island are presented. A numerical model based on the two-dimensional shallow-water wave equations including runup calculations was developed. Numerical model predictions agreed very well with the laboratory data and the model was used to study wave trapping and the effect of slope. Under certain conditions, enhanced runup and wave trapping on the lee side of the island were observed, suggesting a possible explanation for the devastation reported by field surveys in Babi Island off Flores, Indonesia, and in Okushiri Island, Japan.

Experimental investigation of turbulent flow and wind comfort characteristics of fractal wind fences Çoşkun, Şemsi; Kurç, Özgür; Department of Civil Engineering (2017) The characteristics of turbulent flow behind the fractal fences are rather new research area. Previous studies on fractal fences showed that there are clear differences in the flow characteristics as compared with the conventional fences. This study presents the results and comparisons of an experimental study that investigates the turbulent flow and wind comfort characteristics of fractal wind fences. Four different wind fences, three of which have fractal geometries, with the same height, width, and poros...
Linear and nonlinear analysis of human postural sway Çelik, Hüseyin; Gürses, Senih; Department of Engineering Sciences (2008) Human upright posture exhibits an everlasting oscillatory behavior of complex nature, called as human postural sway. Variations in the position of the Center-of-Pressure (CoP) were used to describe the human postural sway. In this study; CoP data, which has experimentally been collected from 28 different subjects (14 males and 14 females with their ages ranging from 6 to 84), who were divided into 4 groups according to their ages has been analyzed. The data collection from each of the subjects was performed...
Numerical investigation of breaking internal solitary waves la Forgia, Giovanni; Tokyay, Talia; Adduce, Claudia; Constantinescu, George (2018-10-04) High-resolution three-dimensional large-eddy simulations are used to investigate the effects of internal solitary waves (ISWs) breaking over a sloping boundary. The lock release method is applied in a two-layer stratified fluid system to generate three different breaking mechanisms (i.e., plunging, collapsing, and surging breakers). The different breaking types are investigated in terms of their effects on the dynamics of the ISW and the interaction of the ISW with the sloping boundary. During each breaking...
Overtopping of solitary waves at model sea dikes Oezhan, Erdal; Yalçıner, Ahmet Cevdet (1991-01-01) This paper discusses an analytical model for solitary wave overtopping at sea dikes. The model is based on the 'weir flow analogy' of Kikkawa et al.(1968). Results of laboratory test on smooth and impermeable model dikes with angles of 45°, 60° and 90° are utilized in constructing the model. Results for solitary waves are compared with those for regular oscillatory waves for the case of vertical dike.
Energy preserving methods for korteweg de vries type equations Şimşek, Görkem; Karasözen, Bülent; Aydın, Ayhan; Department of Scientific Computing (2011) Two well-known types of water waves are shallow water waves and the solitary waves. The former waves are those waves which have larger wavelength than the local water depth and the latter waves are used for the ones which retain their shape and speed after colliding with each other. The most well known of the latter waves are Korteweg de Vries (KdV) equations, which are widely used in many branches of physics and engineering. These equations are nonlinear long waves and mathematically represented by partial...
