Hydraulic Performances of Non-Wave Overtopping Type Seawall Against Sea Level Rise Due to Global Warming

Hydraulic performances of a non-wave overtopping type seawall were investigated on a supposition of the sea level rise that might occur near future. Two-dimensional hydraulic experiments were carried out to evaluate several hydraulic characters, such as a checking effect of wave overtopping, wave overtopping rate, and wave pressure distribution. Some different water level conditions were set in the experiments to reproduce the sea level rise in a supposed range of it. Furthermore, this study proposes an appropriate countermeasure against the sea level rise, and evaluates its efficiency on maintaining excellent hydraulic performances of the non-wave overtopping type seawall.
