N2 - In March 11, 2011 tsunami activated by the 2011 off the pacific coast of Tohoku Earthquake led to several compound disasters in Japan. Many coastal protection structures such as seawalls and breakwaters were damaged seriously but, surprisingly a waste tire retaining wall, located just about 150 m away from a completely collapsed seawall was found to be undamaged. In order to demonstrate how effectively these tires will function against the earthquake and tsunami to protect seawall, a new model was developed and tsunami impact force experiments were performed for a sea wall with model tires behind it (land side). Results from the tsunami impact force experiments showed a better performance of the sea wall when protected with tires placed behind the seawall. At the same time, field test were conducted by cultivating different kind of plants inside the actual tires to maintain the environment. The field test results showed that the greening effect could be maintained by planting trees inside the tires.
