R04.05.13 研究室研修旅行が５月１３日に企画され、メンバーたちが令和２年７月豪雨で被災した熊本県南部球磨川流域の災害復興現場を訪ねました。広範囲浸水被害を受けた人吉市市街地、中川原公園と青井阿蘇神社周辺、遊水地建設が予定される大柿地区と中神地区、引堤や宅地かさ上げが予定される球磨村渡地区と神瀬地区、甚大な被害を受けた八代市坂本町の被災と復興現場見学を実施しました。2年弱経った今でも復旧が続いており、当時の豪雨災害がいかに人々を脅威にさらしたか感じる機会となりました。なお、今回の研修旅行においては、国土交通省九州地方整備局八代河川国道事務所の方々に案内していただき、当時の様子も丁寧に教えて頂きました。深くお礼申し上げます。

May 13, 2022 Laboratory field trip was arranged on May 13 to typical disaster reconstruction sites in the Kuma River Basin located in sourthern Kumamoto. This area suffered from severe disasters caused by the heavy rainstorm in July, 2020. In Hitoyoshi City, we visited the city center, the Nakagawara Park and the Aoi Aso Shrine which experienced large area of inundation during the flood, and the Ohkaki area and the Nakagami area where flood retarding basins were planned. In the Kuma Village, we visited the Watari area where new levee system was planned and the Konose area where the residential land elevation was to be raised. We also visited damaged sites and reconstruction fields in Sakamoto Town of Yatsushiro City. Almost two years passed, but many reconstruction works were still ongoing. The trip provided an good opportunity for us to learn how the heavy rainstorm threatened people at that hard time. This trip was arranged with full support of Yatsushiro River and National Highway Office, Kyushu Regional Development Bureau of MLIT. The staff members are sincerely appreciated for their kind guidance and detailed explanations during the trip.
