Numerical Simulation on Reduced Runup Height of Solitary Wave by Fixed Submerged and Floating Rectangular Obstacles

The wave runup height is one of the most important parameters for affecting design coastal structures such as dikes, revetments, and breakwaters. In this study, SWASH (Zijlema et al., 2011), a non-hydrostatic pressure numerical model, was used to analyze effect reducing solitary waves by submerged floating rectangular obstacles. It confirmed that model reproduces propagation, breaking, quite well. addition, it deformation obstacles well reproduced. Finally, we conducted an examination Reduced heights are calculated characteristics reduction according dimensions obstacle were analyzed. energy attenuation greater than obstacle, shown be more effective in height.
