Long wave run-up on random beaches.
The estimation of the maximum wave run-up height is a problem of practical importance. Most of the analytical and numerical studies are limited to a constant slope plain shore and to the classical nonlinear shallow water equations. However, in nature the shore is characterized by some roughness. In order to take into account the effects of the bottom rugosity, various ad hoc friction terms are ...
متن کاملNumerical modeling of wave run-up along columns of semi-submersible platforms
Wave run-up is one of the most important and effective parameters in designing semi-submersible platforms. Besides unforeseen effects on the movements and response of the platform, wave run up can also cause slamming forces to be exerted on the lower deck of the platform. Therefore, at the first stages of this plan, before running tests on the model of the platform, numerical methods are usuall...
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 کاملPhysical simulation of resonant wave run-up on a beach
Nonlinear wave run-up on the beach caused by a harmonic wave maker located at some distance from the shore line is studied experimentally. It is revealed that under certain wave excitation frequencies, a significant increase in run-up amplification is observed. It is found that this amplification is due to the excitation of resonant mode in the region between the shoreline and wave maker. Frequ...
متن کاملExtreme wave run-up on a vertical cliff
Wave impact and run-up onto vertical obstacles constitutes one of the main phenomena which have to be taken into account in the design of coastal structures. From the linear wave theory we know that the wave height on a vertical wall is twice the incident wave amplitude. Weakly nonlinear theories bring some small corrections to this result. However, in the present study we show that certain sim...
