Storm surges are one of the most important risks to coastal communities around the Bay of Bengal, and it is feared that the threat they pose will increase with climate change in the future. To understand the threats that these events pose, a summary of the field surveys performed in Yangon River Basin after cyclone Nargis in Myanmar in 2008 is presented. Though due to government restrictions survey activities were limited to the area near Yangon city, it was found out that the tide due to the storm surge was probably between 3 and 4 m high and travelled around 50 km upstream of the river mouth of Yangon River. Cyclone Nargis could be accurately reproduced using a numerical model that integrated weather, wave, coastal ocean models, and tide prediction system. The application of such an integrated model is relatively new for storm surge simulation and has never been used for the Bay of Bengal storms. The model was then used to also simulate future cyclones over the Bay of Bengal considering a future climate change scenario.

Tropical Cyclones Affecting Japan Central Coast and Changing Storm Surge Hazard since 1980

Md Rezuanul Islam, Masaki Satoh, Hiroshi Takagi

Summary: This study found that storm surge heights have increased in coastal regions of Central Japan, especially Tokyo Bay, over the past 20 years. This increase is attributed to the stronger and larger tropical cyclones during landfall, as well as the increased frequency of cyclones with northeastward tracks. The positive correlation between surge heights and a hazard index further supports these findings.

Influence of road blockage on tsunami evacuation: A comparative study of three different coastal cities in Japan

Tomoyuki Takabatake, Dawn Han Chenxi, Miguel Esteban, Tomoya Shibayama

Summary: This study developed an agent-based tsunami evacuation simulation model to investigate the influence of seismic damage to buildings and road blockage on tsunami evacuation and expected casualties. The results showed that considering building collapse and road blockage significantly increased the expected mortality rates.

Three-Dimensional Physical Modeling of Tsunamis Generated by Partially Submerged Landslides

Tomoyuki Takabatake, Dawn Chenxi Han, Justin Joseph Valdez, Naoto Inagaki, Martin Mall, Miguel Esteban, Tomoya Shibayama

Summary: This study investigates the characteristics of partially submerged landslide-tsunamis through laboratory experiments and develops a predictive equation to estimate their heights. The results show that wave amplitude, period, celerity, and wavelength do not vary significantly according to propagation angles, but wave dispersion has a significant impact on the propagation process. The volume of a landslide has a greater effect on the height of a partially submerged landslide-tsunami than other parameters.

Simulated effectiveness of coastal forests on reduction in loss of lives from a tsunami

Tomoyuki Takabatake, Miguel Esteban, Tomoya Shibayama

Summary: This study investigates the effectiveness of coastal forests in reducing tsunami-related casualties using simulation models. The results show that coastal forests can reduce casualty rates, but constructing a dyke that can withstand tsunami overflow is more effective. Furthermore, combining coastal forests and a dyke is more effective than using either measure alone.

Developing a Resilience Index for the Pile-Supported Piers of the Port of Batangas under Tsunami Load

Jon Arnel S. Telan, Lessandro Estelito O. Garciano, Mario P. P. De Leon, Tomoya Shibayama

Summary: This study aimed to determine the structural resilience of the pile-supported piers of the Port of Batangas against tsunami loads. It found that the pier with existing batter piles exhibited higher resilience than the one supported by vertical piles in almost 50% of the tsunami load cases.

Global survey shows planners use widely varying sea-level rise projections for coastal adaptation

Daniella Hirschfeld, David Behar, Robert J. Nicholls, Niamh Cahill, Thomas James, Benjamin P. Horton, Michelle E. Portman, Rob Bell, Matthew Campo, Miguel Esteban, Bronwyn Goble, Munsur Rahman, Kwasi Appeaning Addo, Faiz Ahmed Chundeli, Monique Aunger, Orly Babitsky, Anders Beal, Ray Boyle, Jiayi Fang, Amir Gohar, Susan Hanson, Saul Karamesines, M. J. Kim, Hilary Lohmann, Kathy McInnes, Nobuo Mimura, Doug Ramsay, Landis Wenger, Hiromune Yokoki

Summary: Including sea-level rise (SLR) projections in coastal adaptation planning is crucial, but only 72% of coastal practitioners currently utilize them, with lower utilization in developing countries. There is no global standard in the use of SLR projections, but countries with histories of adaptation and consistent national support show greater assimilation of SLR projections.

Development and Implementation of a Smartphone Application for Tsunami Evacuation

Dawn Chenxi Han, Tomoyuki Takabatake, Miguel Esteban, Tomoya Shibayama

Summary: This study proposes the use of a smartphone application as a soft countermeasure to aid with smooth evacuation in the event of a tsunami. By using a GPS-positioning system and accurately reproducing the location of refuge places, the application can guide users to their own location and the designated refuge sites.

A proposal of a semi-empirical method for modifying the atmospheric pressure and wind fields of tropical cyclones

Takumu Iwamoto, Tomohiro Takagawa, Tomoya Shibayama, Miguel Esteban, Martin Mall

Summary: Wind and atmospheric pressure are the main factors in generating storm surges caused by tropical cyclones. However, meteorological models can sometimes have deviations from actual observations. This study proposes a method called GWB-M that modifies both wind and pressure fields in meteorological models based on the dynamic relationship between wind and pressure in typhoons. The GWB-M method is assessed using a storm surge hindcast of Typhoon Faxai in 2019 and shows improvements in wind speed, sea level pressure, and accuracy in capturing maximum sea level anomalies.

Increase in overtopping rate caused by local gust-winds during the passage of a typhoon

Naoto Inagaki, Tomoya Shibayama, Tomoyuki Takabatake, Miguel Esteban, Martin Mall, Thit Oo Kyaw

Summary: This study developed a new numerical model that considers the dynamic interaction of air and water to accurately estimate wave overtopping during typhoons. The model performs well in estimating overtopping rates under strong winds, but further improvements are needed to accurately predict experimental results.
