NUMERICAL ANALYSIS OF BREAKWATER CAPABILITIES OF TSUNAMI PROTECTION AND SEAWATER PURIFICATION

Abstract

 Breakwaters which decrease a tsunami height at baymouth effectively protect bay areas against tsunami damages around the ria coastal line. On the other hand breakwaters have possibilities to harm a water quality environment due to the reduction of water exchange. This study quantitatively evaluates contradictory capabilities of tsunami protection and water purification by tsunami and flow-diffusion simulations. And the method to plan the breakwater construction is proposed.
