| Outline of Annual Research Achievements |
Please refer to the grant proposal for background details of the project. A high-resolution storm surge model is being developed and coupled with a large-ensemble climate dataset in order to quantify changes in urban flood risk. This research is being conducted in two main phases: modeling and simulation.
Work on Phase 1 (model development) continued in FY2023 in order to investigate the role bathymetry plays in urban storm surge amplification. With the aid of two international experts, work continued on a numerical storm surge prototype of Osaka Bay (using a spatially-flexible finite difference scheme). Parallel work on Phase 2 (ensemble simulation) was paused in FY2022 while improvements are being made to a tropical cyclone dataset (generated in FY2021) used for simulations.

Current Status of Research Progress
4: Progress in research has been delayed.
Reason
The research project was scheduled to have concluded in FY2023. However, the principle researcher took maternity leave during FY2023 and research for the project was postponed for six months (2023/8/11-2024/2/13). For this reason, the project was extended one final year and a planned visit by two international collaborators (during the second half of FY2023) was postponed until FY2024.

| Strategy for Future Research Activity |
The new tropical cyclone track dataset (updated in FY2023) will be used to simulate thousands of flood events under present and future climate conditions to test hypotheses and and generalize results.
Arrangements have been made for two international collaborators (Colorado, USA) to visit the principle investigator during April and May of FY2024. The visit will be used improve the numerical model and prepare a manuscript for publication.
Research progress will also continue to be presented at domestic conferences. In early FY2024, a workshop will be held at Kyoto University to support adoption of meshless numerical methods. In early FY2025, a conference session is being organized to facilitate discussion and collaboration around storm surge and coastal-related hazards in Japan.

| Causes of Carryover |
The principle researcher took maternity leave during FY2023 and research for the project was postponed for six months (2023/8/11-2024/2/13). For this reason, a planned visit by two international collaborators (during the second half of FY2023) was postponed until FY2024.
The remaining funding will be used to host the two international collaborators (Colorado, USA) in April and May of FY2024. During their visit, the principle researcher and international collaborators will work on a numerical model and prepare a manuscript for publication.
