Preface 

Japan surrounded by sea has suffered from the lost of human lives and precious estate due to the disaster caused by storm surges, high waves and tsunamis. We have developed the numerical models for the prediction of tsunamis and storm surges and improved design procedures of disaster prevention structures. We carry out studies of reliability and performance based designs to establish new conceptual design methods and have researched how to determine design conditions of disaster prevention structures taking an optimal design into account. Our main targets of coastal disaster from engineering point of view are

• Storm waves
• Storm surges
• Tsunami

and related natural science interests are

• Sea surface wave propagation
• Momentum and heat transfer at sea surface
• Parameterization of air-sea interface

We study the both fundamental natural mechanisms of sea surface and engineering application near the coastal line.
