“…(1) Weather, rainfall, and hydrology Typhoon Hagibis (No. 19) affected a wide area of eastern Japan, with the largest daily rainfall ever recorded in Hakone. This special issue contains papers that discuss dam operations, flood mitigation effects of rice paddies, and the relationship with climate change during the typhoon.…”

“…Tanaka et al 2) examined whether precipitation events that cause the same level of flood discharge and number of inundated water systems as Typhoon Hagibis (No. 19) are likely to occur in the future, using bias-corrected d4PDF data for 31 river basin systems in eastern Japan. The frequency with which the annual number of inundation systems exceeds 6, the number of inundation systems in the typhoon, is estimated to increase from about once every 400 years in the past climate to once every 20 to 30 years in the 4degree increase experiment, indicating an important result concerning disaster risk management in a wide area.…”

“…Matsuda et al 19) investigated the damage to river structures (mainly river embankments) of the Chikuma River during the East Japan Typhoon Disaster of 2019 from the viewpoint of hydraulic phenomena, using aerial photographs taken before the disaster, aerial photographs taken by a drone after the disaster, and ground photographs. The paper also compares the results with those of a survey of damage to rivers in Hokkaido, and is commended for pointing out the problems of river structures.…”

“…Typhoon Hagibis (No. 19), which occurred in 2020, was a large and fierce typhoon that caused record-breaking rainfall over a wide area in Japan, including the Kanto-Koshin region, Shizuoka and Niigata Prefectures, and Tohoku regions, resulting in extensive damage in many areas. As a result of the record-breaking rainfalls, levees were breached at 140 locations on 71 rivers in 20 river basins, including 12 locations on 7 rivers in 6 river systems managed by the national government, resulting in large-scale flood damage.…”

In 2019, the Kanto-Koshin area and the Tohoku area suffered devastating damage from floods and sediment disasters caused by the record-breaking heavy rainfall that came with Typhoon No. 19 (Hagibis). In the same year, the heavy rainfall caused severe damage in the northern part of Kyushu area, such as Saga Prefecture, as well as the wind and rain disaster caused by Typhoon No. 15 (Faxai) in Chiba Prefecture. These disasters also highlighted the danger posed by a series of disasters that could cause extensive damage in large areas due to combinations of multiple factors. It is one of the missions of JSCE to compile and disseminate lessons learned from disasters in Japan for solving future challenging issues in managing infrastructures and mitigating disaster damage. This special issue on the storm and flood damage in 2019 in Japan includes valuable information on the disasters in 2019 from different disciplinary points of view, aiming to contribute to the growth and development of interdisciplinary academic fields of civil and environmental engineering.
