Typhoon Jebi struck Japan on the 4 September 2018, damaging and inundating many coastal areas along Osaka Bay due to the high winds, a storm surge, and wind driven waves. In order to understand the various damage mechanisms, the authors conducted a field survey two days after the typhoon made landfall, measuring inundation heights and depths at several locations in Hyogo Prefecture. The survey results showed that 0.18–1.27 m inundation depths were caused by Typhoon Jebi. As parts of the survey, local residents were interviewed about the flooding, and a questionnaire survey regarding awareness of typhoons and storm surges, and their response to the typhoon was distributed. The authors also mapped the location of some of the containers that were displaced by the storm surge, aiming to provide information to validate future simulation models of container displacement. Finally, some interesting characteristics of the storm surge are summarized, such as possible overtopping at what had initially been thought to be a low risk area (Suzukaze town), and lessons learnt in terms of disaster risk management are discussed.

Vulnerability Functions

Container yards tend to be located along waterfronts that are exposed to high risk of storm surges. However, risk assessment tools such as vulnerability functions and risk maps for containers have not been sufficiently developed. In addition, damage due to storm surges is expected to increase owing to global warming. This paper aims to assess storm surge impact due to global warming for containers located at three major bays in Japan. First, we developed vulnerability functions for containers against storm surges using an engineering approach. Second, we simulated storm surges at three major bays using the SuWAT model and taking global warming into account. Finally, we developed storm surge risk maps for containers based on current and future situations using the vulnerability function and simulated inundation depth. As a result, we revealed the impact of global warming on storm surge risks for containers quantitatively.

One Year

In 2006, Hyogo prefecture opened the “Araihamakaze” park on reclaimed land leased with cooperation from some companies, and set up a seawater pond called “Konourafuna Ike” in the park. The initial plan was to make this seawater pond into a Satoumi, but since the water in the pond was stagnant, algae flourished making it uninhabitable for other living creatures. The authors conducted investigative research to implement activities for improving the environment and popularizing the park. This report is a summary of the results obtained and challenges faced while conducting these activities in the area over one year, which included involving the local schoolchildren in constructing tidal flats. The answers to the questionnaire revealed that schoolchildren understood that the nutrients in the seawater pond “go round and round” through the food chain and are utilized by living creatures. They realized that this process is called “circulation.”To the question, “Do you want to develop tidal flats?” 9 of the 10 children answered YES. However, only 50% of the children understood that a measure to prevent the degradation of the environment of the seawater pond is to “Construct tidal flats,” which suggested that there is a need to correlate the issues and the solutions to enhance their understanding.

In the planning of the Delta-works, carried out in the Southwestern Netherlands, the Eastern Scheldt was the largest and therefore last tidal basin to be fully closed mainly to protect the area from floods. Increased recognition for the natural value of estuaries and a strong lobby from nature conservationists and shellfish producers led to a reconsideration of original plans, confirmed by a series of governmental decisions. Per consequence execution of the present plans will result in a storm-surge barrier at the entrance of the tidal basin together with two partitioning dams, separating the (reduced) tidal Eastern Scheldt from a new freshwater lake. Attention is paid to the present values in the Eastern Scheldt and briefly to changes involved by the project. The decisionmaking process is described and discussed: In the course of the project the majority of decisions taken were prepared by teams of ecologists, civil engineers, hydrologists and financial experts using policy-analysis methods. For guidance of developments in the influenced area the local government accepted a policy plan, in which human uses are regulated. Operations of the barrier are designed such that safety from flooding is guaranteed, while adverse effects for the tidal ecosystems are minimized.
