GEOTEXTILE REEF AS A COASTAL PROTECTION AGAINST TSUNAMI

摘要

The possibility of an application of an artificial reef as a mean for coastal protection against tsunami impact is examined. Reef feasibility and its hydraulic performance are investigated numerically for different obstacle configurations and varying incident wave conditions, taking into consideration the experience available on the storm wave attenuation by means of such structures. Effect of the reef on tsunami damping is discussed by comparing the phenomena observed in the case of a coastline protected by a reef and the case without the protection.
