Numerical Study on Breakwaters by the Accurate Particle Method
Publication: Coastal Structures and Solutions to Coastal Disasters 2015: Resilient Coastal Communities
ABSTRACT
In recent years, the required performance of breakwaters against tsunamis or high waves is increased. In Japan, the design concept of breakwater has been changed after the 2011 off the Pacific Coast of Tohoku earthquake with subsequent huge tsunami. However, the details of property of such huge waves are not studied sufficiently due to difficulty in measuring them, and thus, numerical approach is increasingly expected as the alternative. This paper presents numerical simulations targeting composite phenomenon with overflows and overtopping waves acting on breakwaters by using the recently developed accurate particle methods with a porous model for reproduction of permeability of caisson mounds. From the results of the numerical simulations, the structural effectiveness of the breakwaters with a parapet is discussed from the viewpoint of the wave pressure and velocity fields of overflows.
