被災が頻発した中小河川における河川護岸の事例調査について（報告）

抄録

In the event of a disaster in Iwate Prefecture and Hokkaido by Typhoon No.10 in 2016, prevention of disasters in small and medium rivers is considered as an important subject to achieve at present and in the future. Based on these circumstances, in disaster recovery, it is thought that it will become increasingly important to make every possible effort for the infrastructure measures as a prevention of recurrence of disaster. On the other hand, it is observed that in various cases small and medium sized rivers have been suffered by disaster repeatedly in a relatively short period of time. Therefore, the authors implemented the field surveys in three rivers which were selected based on organizing and analyzing the disaster application documents. As a result of the field surveys, the points which need to pay attention in disaster restoration have been found.
