ABSTRACT
The new approach towards the mitigation of major disasters, such as tsunami, is to promote dual-use technologies to improve the resiliency of the biophysical and socioeconomic systems. This chapter explains how the groins that have been designed for coastal protection have proved beneficial in the mitigation of the adverse consequences of the tsunami. This results of the posttsunami survey clearly indicate that the coastal protection structures (engineering structures, vegetation, etc.) helped in the mitigation of the adverse consequences of the tsunamis. They would be equally protective against extreme weather events, such as tidal waves and hurricanes when they happen.
