In the heavy rain disaster that struck the Kanto and Tohoku regions in September, the Ministry of Education, Culture, Sports, Science and Technology (MEXT) provided a scientific research grant of 9 million yen for a comprehensive survey of disaster scale and countermeasures led by Professor Shigenobu Tanaka of Kyoto University. I decided to issue.The aim is to use it as a countermeasure against heavy rain disasters, which are worried about frequent occurrence due to climate change caused by global warming.
Specific investigation and analysis work includes (48) analysis of the causes of heavy rainfall exceeding 600 mm for a maximum of XNUMX hours in northern Tochigi Prefecture (XNUMX) scientific analysis of topography and geological characteristics at the damaged part of the embankment in Joso City, Ibaraki Prefecture (XNUMX) Kinugawa Evaluation of the river channel reduction effect included in the planned high water flow rate of the hydraulic control plan ④ Investigation of inundation damage due to levee flooding ⑤ Disaster prevention in Joso City, verification of evacuation information transmission, etc.
From September 9th to 9th, the Kanto and Tohoku regions were hit by heavy rainfall of over 11 mm for up to 48 hours in northern Tochigi prefecture, and 600 rivers had levee breaks, water leaks, and floods.In Joso City, a wide area surrounded by the Kinugawa and Kokaigawa rivers was submerged, and many railway lines in the northern Kanto region were severely damaged due to the outflow of embankments.Many meteorologists have warned that typhoons will become huge and guerrilla rainstorms will occur frequently due to climate change caused by global warming, and there are concerns about the frequent occurrence of such damage in the future.
