| 内容記述 | The effect of tsunami energy dissipation of disaster-prevention farmland was evaluated by ahydraulic model test and a numerical simulation. The Tohoku earthquake on 11 March, 2011 caused a huge tsunami disaster, especially along the coast of the Tohoku region of Japan. NARO has proposed using disaster-prevention farmland to mitigate damage caused by tsunamiin coastal farmlands, but its effectiveness for dissipating tsunami energy has not been clarified. We conducted hydraulic model tests to evaluate the delay of tsunami run-up to a residential area, and found the tsunami was delayed by 130 s for short-wavelength tsunami. The short-wavelength tsunami did not reach the residential area in the case of disaster-prevention farmland, but reached the top of the residential area in the case of normal farmland. In the case of long-wavelength tsunami, the volume of tsunami that overflowed the coastal dike exceeded the capacity between the coastal dike and a third dike and reached the residential area. However, the energy of the long-wavelength tsunami that reached the residential area was dissipated by the second and third dikes. A numerical simulation evaluated the effects of disaster-prevention farmland in a model district. The simulated inundation area of existing farmland, the case with a higher coastal dike, and the disaster-prevention farmland were compared. The area inundatedby the tsunami in the higher coastal dike was narrower than that of the existing farmland. However, the difference of the inundation area was small. The inundation area of the disaster-prevention farmland was similar to that of theexisting farmland because the heights of the coastal dikes were the same. However, the velocity of tsunami run-up was slower in the disaster-prevention farmland. Thus, it is concluded that disaster-prevention farmland is an effective revival plan for the model district. | |||||||||||||||||||||||||||||||||||||||||||||
