Aspects of Inundated Flow Due to the 2004 Indian Ocean Tsunami

Abstract

This paper reports the results of field surveys of the 2004 Indian Ocean Tsunami in Southern Thailand and Northern Sumatra. After outlining the general state of the tsunami strike, tsunami height and distribution in Sec. 3, aspects of inundated flow such as current velocity (water particle velocity), fluid force, relation between inundation depth and the degree of damage to reinforced concrete buildings, shape and height of surge front, inundated flow with floating bodies, effects of coastal forest on reducing tsunami energy and force are discussed. Damage estimation problems are also discussed. A simplified theory for predicting the moving velocity of floating bodies with inundated flow is presented.
