本研究调查了2018年台风Jebi引起的日本和歌山县有田市Minatomachi的洪水特征。首先进行了实地调查，以捕捉淹没面积和淹没深度在一个见证的时间。调查结果和对当地居民的访问显示，风暴潮和海浪的漫顶是造成洪水泛滥的原因。系统地结合了用于估计浪涌、波浪和淹没的三种数值模拟来代表观察到的淹没特征。模拟结果合理地反映了实测淹没面积随水深的变化规律，并指出越浪量是造成淹没的主要因素。结果还表明，亚重力波，在风暴下发展，可能有一个显着的影响，洪水。
This study investigated inundation characteristics at Minatomachi in Arida City, Wakayama Prefecture, Japan, induced by the 2018 Typhoon Jebi. Field surveys were first conducted to capture the inundation area and the inundation depths at a witnessed time. The survey results and interviews of local residents indicated that wave overtopping of the stormy waves, as well as the storm surge, contributed to the inundation. Three numerical simulations for estimating the surge, waves, and inundation were systematically combined to represent the observed inundation characteristics. The simulation result reasonably presented the observed inundation area with the depths and indicated that the wave overtopping was the primary factor for the inundation. The results also implied that infragravity waves, developed under the storm, might have a significant impact on the inundation.
