Abstract
Ports and coastal industrial and commercial regions in Osaka bay were inundated with water due to storm wave overtopping during Typhoon Jebi passing through on September 4, 2018. Although the large storm surge was observed at the end of the bay, the sea level rarely rises over seawalls which prevent sea water from intruding onto residential areas, fortunately. Therefore, in this study, the characteristics of wave runup over the gap between berthing depth and quay top in high, normal and middle tide condition are investigated with vertical 2D model experiments. Moreover, numerical simulations are conducted by using a Boussinesq-type wave model, which can be also applied to wave overtopping and inundation in horizontal 2D computational region, to reproduce the results of model experiments.Recorded Presentation from the vICCE (YouTube Link): https://youtu.be/HCiUoj68xyY
