Abstract—Coastal sedimentation is a crucial topic in the field of modern coastal engineering. In general, coastal sediment-transport mechanisms are changing because large-scale coastal engineering projects have blocked coastal sediment transport, regional coastal development has destroyed natural protective barriers, and climate changes and global warming have caused sea levels to rise and changed wave flow fields. This study used Stokes 2nd theory as the theoretical basis for nonlinear waves in nearshore non-breaking regions. In addition, in nearshore wave-breaking regions, flow velocity at the bottom approximates sawtooth waves. If the difference in the wave steepness or the water depth parse obtained the surf similarity parameter is larger, the smaller the asymmetry parameter.
Index Terms—Sawtooth waves, surf similarity parameter, asymmetry parameter.
