Abstract

When a tsunami of large magnitude strikes a coast line, various kinds of disaster such as loss of lives, properties or public investments are caused by inundation of tsunami over nearly horizontal area. Although tsunami runup has been investigated for the sloping beach, these populated area is bordered on sea by a vertical wall such as a quaywall or a highway revetment. In this paper, transformation of tsunami waves at a vertical quaywall is analysed using U-C characteristics and overland flow is treated. Effectiveness of a vertical land dike aiming to stop running water is investigated also. Theoretical results are verified by experiments.
