چکیده
The objective of this study was to investigate experimentally solitary waves run-up on sloping beaches. Conducted in the Super wave flume(5m×5.2m×300m) and the Large wave flume(2m×2m×200m)at Tainan Hydraulics Laboratory (THL), solitary waves were generated by moving the wave board forward in the manner of ramp-trajectory and solitary-wave-trajectory separately to simulate the various of wave height and to observe their run-up process. Experimental results show that the gentler slope is, the smaller run-up bring about on the same tsunami. Compared to relative research, simulation results of tsunami which is generated by driving the waveboard one way linearly forward on a 1/20 sloping beach possess the higher run-up height than Synolakis(1987) proposed on solitary waves. This inference is quite different from Synolakis(1988) asserted that the solitary waves are the limiting waves in simulating tsunami run-up.

Investigating the Amount of Forces Caused by Solitary Waves on Coastal Walls Using OpenFOAM Software
Coastal walls (dyke) are one of the methods of protecting the coast against coastal erosion and destructive forces of waves. The purpose of this study is to simulate the wave collision with the coastal dyke and compare the results with the laboratory model. Open FOAM open source software and K-ω SST turbulence model were used to simulate the amount of wave consumed by the coastal dyke. Taking i...
متن کاملISPH Numerical Modeling of Nonlinear Wave Run-up on Steep Slopes
Non-breaking tsunami waves run-up on steep slopes can cause severe damages to coastal structures. The estimation of the wave run-up rate caused by tsunami waves are important to understand the performance and safety issues of the breakwater in practice. In this paper, an Incompressible Smoothed Particle Hydrodynamics method (ISPH) method was utilized for the 2DV numerical modeling of nonli...

متن کاملExperiments on Internal Wave Resonance in Periodically Forced Lakes
Laboratory experiments were conducted to determine the steady state internal wave response of a periodically forced long and narrow lake. The system is two-layer stratified and is subjected to periodic forcing over a wide frequency range. The ratio of the forcing frequency (f) to horizontal mode-one (H1) internal seiche frequency (fH1) governs the system response. For f ≥ 2fH1, highermode inter...
