TSUNAMI WAVE LOADING ON A STRUCTURAL ARRAY PARTIALLY SHELTERED BY A SEAWALL

In recent years tsunamis have been recognized as one of the most catastrophic natural disasters in world, highlighted by 2004 Indian Ocean tsunami and 2011 Tohoku earthquake tsunami. These countries affected like Indonesia, Thailand Japan usually arm their coast with sea walls to provide protection for coastal urban regions; however, surveys found during both events, several sections breached had led extensive damage those regions (Dalrymple Kriebel, 2005; Sato, 2015). Previous studies examined sheltering effect macroroughness individual structures, but limited knowledge is available on flow concentration a partially standing wall field structural array. The result from this experiment will serve better understanding loading variation induced different length partial seawalls, help prepare more accurate hazard maps events.
