1. Introduction
Tsunami disasters occurred frequently in the last decade and damaged coastal structures (Nandasena et al., 2012). In general, tsunami waves are faster, higher and stronger than wind waves or storm surges. Tsunami generation cannot be predicted because tsunamis are caused by the sudden displacement of significant volumes of ocean water, originally triggered by earthquakes, landslides, volcanic eruptions, or meteors (Al-Faesly et al., 2012). On 26 December 2004, a tsunami was triggered by a 9.1 magnitude earthquake in the Indian Ocean. The maximum run-up height of the tsunami wave was 30 m, causing over 200,000 fatalities in N10 countries bordering the Indian Ocean (Grilli et al., 2007). On 27 February 2010, a tsunami was triggered by an 8.8 magnitude earthquake off the coast of Chile. The tsunami reached a localized run-up of 29 m on a coastal bluff (Fritz et al., 2011). On 11 March 2011, a 9.0 magnitude earthquake occurred near the northeast coast of Japan, and the tsunami swept along the coastline and penetrated inland with maximum run-up heights of 40 m (Yeh et al., 2013). On 16 September 2015, an 8.3 magnitude earthquake struck off the central coast of Chile, and triggered a tsunami with a maximum run-up height of 13 m (Contreras-Lopez et al., 2016). Many port structures have been damaged by tsunamis. For example, in Thailand, dock slabs in Khao Lak port were displaced, and decks of Ban Nam Kem fishing port were severely damaged by uplift pressure due to the 2004 Indian Ocean tsunami (Ghobarah et al., 2006; Lukkunaprasit and Ruangrassamee, 2008). In Indonesia, the Banda Aceh port area was isolated and inaccessible, and the oil transfer facility of Kreung Raya port suffered extensive damage in the 2004 Indian Ocean tsunami (Ghobarah et al., 2006). In Japan, Sendai port in the Tohoku region was damaged in the 2011 Japan tsunami, and damaged containers can be clearly seen in satellite images (Suppasri et al., 2012). In the experimental environment, a dam break flow has generally been used to simulate a tsunami bore (Nandasena and Tanaka, 2013), because the run-up motion of the tsunami bore on a dry bed is similar to that of a dam break flow (Chanson, 2006; Chanson, 2009). The analytical solution for dam break flow proposed by Chanson (2005) was compared tsunami-induced hydraulic bores that were observed during the 2004 Indian Ocean tsunami, and good agreement was observed between the analytical solution and the field data, in terms of the bore front shape. This suggests that the dam break phenomenon can be used as a method to simulate tsunami-induced hydraulic bores (AlFaesly et al., 2012). Various simple equations have been proposed for estimating tsunami bore velocity (see, e.g., FEMA, 2012; CCH, 2000; Murty, 1977; Kirkoz, 1983; Iizuka and Matsutomi, 2000; and Bryant,
