12月11日と15日に、毎年の恒例の洗掘・浸食問題に関する日仏セミナーを、今年はオンラインで開催し、東大、鉄道総研、ギュスターブエッフェル大学、フランス国鉄、Ceremaから多くの研究者・技術者が参加しました。
Assoc. Prof. Kenji Watanabe and Dr. Christophe Chevalier (Gustave-Eiffel Univ., France) organized “2020 Online seminar on Scour and Erosion”. Many researchers and engineers from Japan (UTokyo, Railway Technical Research Institute) and France (Gustave-Eiffel Univ., SNCF, Cerema) joined this seminar.UTokyo, Gustave-Eiffel Univ.(formely IFSTTAR) and RTRI regularly hold French-Japanese workshops on Scour and Erosion, once a year in Paris or in Tokyo. This year, we gave up holding such face-to-face workshops, and tried to do it online. Online seminars are useful and convenient, but all participants feel it is better to meet in real, in order to promote mutual understanding.
