... rate at a storm surge level larger than the crest level of the seawall. The pore pressure inside the backfill stone almost equals the wave pressure in front of the caisson. Moreover, high water level induces water to flow out from the backfill stone opening. INTRODUCTION Future climate change could...

.... According to the time scaling principle, the length and thickness of the seabed in prototype of test S5-1 were 10m and 5m, respectively. The maximal wave pressure p0 applied to the seabed surface was 7.7kPa, the wave period T was 4.5s and the wavelength L was 25m. The wave pressures applied to the central...
