内容記述 |
This research paper describes the tsunami damage to tide walls observed using aerial photographs and field investigations at 13 locations along the coast of Iwate Prefecture, where significant tsunami damage occurred as a result of the Great East Japan Earthquake. This paper also summarizes the characteristics of the damage. The tide walls in Iwate Prefecture were constructed on a ria (hilly type) coast, this geographical feature of Iwate being different from that of the other disaster areas, primarily Miyagi and Fukushima Prefectures. The tide walls constructed in Iwate Prefecture can largely be classified into two types, i.e. sloping and vertical. The vertical type can be subdivided according to whether or not there is a back slope. The results of our investigations show that all the devastated tide walls suffered from overflow before being damaged. In particular, the sloping and vertical type tide walls with slope protection were damaged by scouring of the infill sand or back fill soil due to the overflow of the tsunami. In the case of vertical type tide walls without slope protection, damage was caused by scouring of the back fill soil. |
